Want to play your Sega Dreamcast games but don’t want to haul the console out of the closet? You’re in luck, because there exists an outstanding emulator that I recently became addicted to: nullDC. This article covers all you need to know about it, including how to get started. So what are you waiting for? SoulCalibur is waiting.

Introduction

As a gamer, one of the worst experiences is finding out that your favorite console is reaching its end-of-life stage. Yet, it’s inevitable. Also inevitable is the fact that fans will create an emulator to make sure that the platform never dies. Luckily, pretty-well every console prior to and including the Sega Dreamcast have stellar emulator options available. That = a lot of gaming potential.

Nearly five years ago, I wrote a how-to entitled “Game Emulation in Linux“, which as the title implies, talked about getting various emulators working under the OS along with a gamepad. At the end, I stated, “The only other system I really wanted to see an emulator for, but didn’t, was the Sega Dreamcast. I guess we can’t have it all!” This sentiment was directed at Linux, but the truth was that the options were ultra-limited for Windows as well.

As it’s been a while since I last gave any Dreamcast emulator a test, I decided to once again seek out the available options and see how they fared. To my surprise, I found two popular choices: DEMUL and nullDC. For various reasons, I didn’t have luck with DEMUL at all, after a couple of nights of testing. nullDC on the other hand, I had working no problem, so that’s the focus of this article. Unfortunately for Linux and OS X users, neither of these emulators are designed for either OS – though Wine might be an option on the Linux side.

What Makes nullDC Great

It’s open-source. Want to contribute? You can!

The most important factor that sets an emulator apart from the rest is how well it works. In the case of nullDC, my overall experience has been amazing – much better than I anticipated. In all of the games I tested with nullDC (about 80), each one that worked delivered the same audio I’d expect to get from the console, and for the most part, the same could be said about the graphics. There are occasions where texture glitches occur or fonts may not render ideally through the emulator as they would on the console, but so far I haven’t encountered any problem too notable.

You might have noticed that I mentioned “each one that worked” above, and that’s because not all games are going to work with nullDC. The limiting factor is WinCE. If a game happens to use it, then it will not work in nullDC. It’s worth noting that DEMUL does support WinCE, so that is one thing that does set the two emulators apart. Select games that run on WinCE and subsequently won’t operate in nullDC are Resident Evil 2, Armada, 4×4 Evolution, Matt Hoffman’s Pro BMX, POD SpeedZone and Ducati World.

If you’re familiar with emulators, chances are you know how tedious it can be to find the right plugin for each module of a console, such as graphics, audio, gamepad and so forth. This is one area where nullDC shines (or doesn’t, depending on your view), as it pre-bundles all of the plugins right inside of the main package. That means that you’ll be able to get going fairly quickly without having to hunt down different plugins from a bunch of different websites. The downside, however, is that if one plugin doesn’t really agree with you, then you are somewhat out of luck. I’ve been unsuccessful in trying to find alternate plugins for nullDC.

Setting it Up

nullDC doesn’t have much of an official website, but rather is hosted via Google’s ‘code’ project hosting here. You’ll want to download the non-NAOMI version of the emulator, and then extract it. There’s no installer for this emulator, so wherever you extract it is where it will run from.

nullDC Sega Dreamcast Emulator

Like most emulators, nullDC requires a BIOS to operate, and adding to the similarity, it’s the one thing that doesn’t come included with the program. The reason for this is that the developers don’t want to risk angering Sega’s lawyers, and I don’t blame them. A quick Google search for ‘nullDC BIOS’ will yield quick results, or for a safe download I recommend grabbing it here. You will need to place the BIOS and other files in the archive into the ‘data’ folder within the nullDC folder.

Once that’s done, nullDC should load up without a hitch. If it complains about not being able to find the BIOS, double-check that it was extracted to the proper folder (‘data’) and also that its naming scheme is appropriate (‘dc_boot.bin’).

Your first stop should be Options > Select Plugins. The first four options can be left alone; it’s the “Maple” section that’s to be tackled. Maple is the plugin for gamepads, VMUs and other things. For some reason, I couldn’t get my Xbox 360 gamepad to work with the default plugin here, so I changed it to “PuruPuru Dreamcast Controller”. For extra save space, I added a second VMU to the first gamepad, and then two more to my nonexistent second gamepad.

nullDC Sega Dreamcast Emulator

At this point, there’s just one more important thing to take care of: gamepad configuration. To handle this, you need to go to Options > Maple > Port A > and then use the configuration tool for whichever plugin you’re using. Here’s the configuration screen for PuruPuru and also how I have my Xbox 360 gamepad setup for it:

nullDC Sega Dreamcast Emulator

With gamepad configuration dealt with, you’re effectively done and ready to go. You might however want to spend a couple of minutes looking through the various tweaks in the Options menu, such as changing the default region or altering some of the graphics modes. Two options I personally enable are Per Triangle under the Sort section in the PowerVR menu, and also Extra Geom under the Aspect Ratio section in the same menu. The latter option helps reveal more of the game on each side, effectively making 4:3 games run with a widescreen ratio. This is not done by stretching, but rather revealing the extra area that the console itself would crop out. You will see some garbage on the sides on occasion, but the widescreen effect once in a game that supports it is generally worth it.

nullDC has the tendency to crash on occasion, so once all of your configuration tasks are handled, I’d recommend closing down the program and reopening it before loading up a DC game, just in case.

  • Serin

    Had anyone compiled for x64? I get message about incompatibility on win 8 and it won’t launch. I have been using chunkast which launches and boots to main screen but can’t read utopia or otherwise boot

    • http://techgage.com/ Rob Williams

      That’s bizarre. I have no problem at all running it on Windows 8 / x64.

  • bamminer

    Hi, I’m not looking at my PC right now, but I can tell you that I run Dreamcast games almost perfectly on NullDc 1.6 or something like that. My specs are as follows: P4 HT 3 GHz | 80 GB HD on 2 drives | 3 Gb Ddr-Ram | Int. Graphics circa 2005-ish| WinXP. I do run every non WinCE game perfectly with one exception: Sonic Adventures pauses occassionally(2-3% of the time), but is very, very playable otherwise. I know that NullDc has WinCE issues(most games will stop before completion). NullDC 3 and 4 will not run with games. Is there a way to play WinCE Dreamcast games via emulator with my specs?

    • http://techgage.com/ Rob Williams

      It might be worth testing the games out with DEMUL. When I wrote this article I had poor luck with it, but since then it’s treated me a lot better. As far as I was aware, nullDC didn’t run WinCE games at all. It’s a little unfortunate to see the project hasn’t been updated since 2011 (DEMUL was updated late 2013).

  • joeace

    The emulator is working but when I get to the time and date setting screen I can’t do anything. Is something wrong with the emulator or is it just my computer?

    • http://techgage.com/ Rob Williams

      Are you able to play a game, or is it just the BIOS section of the program that’s not working? Is a gamepad configured properly?

      • joeace

        I tryed to boot up the rom for sonic adventure but it just went to the date/time screen and wouldn’t do anything. I can’t figure out how to configure the gamepad.

        • http://techgage.com/ Rob Williams

          It kind of sounds like the image you’re trying to boot from isn’t working right with nullDC, or, something might still be off with the configuration. Note that some games you procure online might not be designed to work with nullDC; you’ll want ones that have a .bin and a .cue. If you have a release that has a bunch of files, it’s either meant to be burnt to a CD so that it can run on a real Dreamcast, although it might also work in Demul (for .gdi Demul is the go-to emulator).

    • Zach

      up/down is change settings, left/right is select setting. v is a…why?

  • Gregory Price

    I have windows 8 I can’t get a smooth play out of my emulator I’m using a hp 2000

    • http://techgage.com/ Rob Williams

      Is that the low-end HP 2000 notebook? If so, that right there is the reason for the poor performance; emulation requires beefy hardware to run at its smoothest. You might be able to eke additional performance out of that notebook, but it’s hard to say. I’d recommend submitting a question here as someone might already have a solution to your problem: http://reddit.com/r/emulation

  • vaealive5

    I am also having a issue with this emulator. Been playing skies of arcadia, a .gdi file, and randomly it starts asking for the date and time. It never did this for the hours of time I’ve put into playing. Now whenever I set the time and continue I am met with a black screen of death. This makes no sense because it never did this and I’ve spent about 9 hours playing without A SINGLE problem.

    • http://techgage.com/ Rob Williams

      You might want to see about continuing the quest from Demul. The memory card files are plugin based, so you can carry your nullDC saves over as long as you are using the same plugin. If you do this though, make absolute certain you back things up just in case.

      That’s unfortunate about that game though. SoA is one game I had on my list to play through again down the road.

  • Shane

    Hey I downloaded NullDC and I got it up and running. But when I try to normal boot a game a message pops up saying that NullDC has stopped working and it just has me close it. What should I do?

    • http://techgage.com/ Rob Williams

      That’s usually the result of a bad plugin configuration. You’ll need to double-check all of the settings. If you configured the video, you might want to reset it to default settings until you can get the emulator working at all.

      • Shane

        I re-downloaded the emulator and now every thing is all up and running! Thank you very much for your help!

        • http://techgage.com/ Rob Williams

          I’m glad that you got it sorted out!

  • chris thorns

    I have nulldc it’s a Cool emulator but my issue is the choppy audio I’m getting I’ve tried numerous configuration and it’s still there but gameplay runs smooth just the audio choppy and echoing any solution

    • http://techgage.com/ Rob Williams

      That’s the problem with emulation in general… all of our PCs are different, and so one configuration might work well for someone, it might not for another. When it comes to a problem like that, it’s best to seek out alternative plugins. It could just be a sound card issue though (and I’m sure it’s obvious, but it wouldn’t hurt to tweak the audio settings for whichever plugin you’re using).

      • chris thorns

        Cool thanks for the Reply now with that been said how can I go by using alternative methods for this issue are there any downloads I can do or website I can go to or do u have a link I can go straight to?…..again thanks for your response

        • http://techgage.com/ Rob Williams

          So, I’m pretty certain you must have, but just to be sure, did you use the option to sync audio in the plugin that comes with it? I looked around, and I guess I might have been wrong… I can’t find another audio plugin for that. Is this issue common across all games?

          You might want to try DEMUL instead, as it offers its own plugin that might work better.

          • chris thorns

            yes i’ve tried all that with sync etc. but still choppy and echoing…..however i have not tried the demul version….again if u have a link to demul please send it if u don’t mind and again thanks for your responses to my issues.

          • http://techgage.com/ Rob Williams

            DEMUL is an entirely different emulator. Unlike nullDC, it can run the Windows CE-based games (well, most of them).

            http://demul.emulation64.com/

            You might want to copy the plugins over from nullDC, and you will definitely need to copy over the BIOS.

          • chris thorns

            ok i have downloaded demul 0.57 now jus trying to figure out the configurations on it and you’re right i see it’s totally different looks like it has it’s own everything. but im trying to find a tutorial on how to set everything up but i haven’t found anything as of yet again if there’s a link that shows a tutorial please send as always thanks for your response and help with this isuue

          • http://techgage.com/ Rob Williams

            Shoot me an email at rob.williams@techgage.com and I’ll shoot over the exact install folder I use.

  • chase

    I need help. Whenever I start up a game on nullDC it just doesn’t do anything. I’m not sure what’s going on and I’d appreciate help.

    • http://techgage.com/ Rob Williams

      Are you trying to boot a Win CE-based game? A list can be seen here:

      http://www.dcemu.co.uk/vbulletin/threads/43804-WinCE-games-List

      DEMUL would be required for those titles. If that’s not the problem, you’ll want to double-check all of the plugins. See if you can make it so that you can boot into just the BIOS.

  • dustin

    im using null and when I load my rom it freezes on the sega screen

    • http://techgage.com/ Rob Williams

      Are you running this on an older PC? Does it do that with every ROM? I’ve had issues with certain ROMs on occasion, but it’s not that common. You might want to try DEMUL to see if you have better luck.

  • Robert

    Howdy, I have an issue I hope someone can help with. I been playing Skies of Arcadia on this thing for the last couple weeks. I’ve had no issues except minor texture ones (and the fact it’s a nightmare to find chams w/o the VMU indicator lol) Yesterday, it crashed after playing it for around 11 hrs straight. Being late, and the fact I’d saved like 5 mins prior, I went to sleep without restarting it. (First time it’s ever crashed) Today, I went to resume but after clicking start and selecting the gdi, it popped up with a blue screen asking for a date and time (never has done that before, has always just loaded the intro for Skies) after setting date and time, the screen goes black and it doesn’t do anything else. I can’t figure out what’s wrong. I went and looked at all settings and plugins, no changes. I restart and it asks for date/time again. restarted computer too. I’ve got like 40-50 hrs logged on the game, PLEASE HELP!

    • http://techgage.com/ Rob Williams

      First and foremost, backup your VMU data (the vmu_data_portXX.bin files). Also note the “Date modified” to make sure that the last time you saved your game, it actually did save it. As for that issue ,it sounds bizzare. It almost seems like it’d be a good idea to redo your entire nullDC installation, and then import your VMU data.

      If you want to email me your VMU files (rob.williams@techgage.com), I can have a look at them and make sure they are not corrupt. I am really hoping the crash didn’t affect those.

      • Robert

        Thanks for the ultra fast response. It’s working perfectly now, The thought had crossed my mind to re-extract a new nulldc folder but I didn’t know where the games saves were, Still no idea what changed with the crash, but at least I can continue play. On a side note, I don’t suppose there’s any way of playing the pinta’s quest VMU minigame?

        • http://techgage.com/ Rob Williams

          I’d still make sure you make regular backups of the VMUs, because it’s going to be painful if you ever do experience a serious crash.

          If you can control the VMU minigame with the gamepad, you should be able to just use windowed mode and view the VMUs, but if it requires the VMU controls themselves, then you might want to look into a VMU emulator, or a plugin that might allow it. This is not something I’ve done before.

          • Robert

            It’s not playable from within skies at all. from what I understand, Skies downloads it to the VMU and then you play it in the VMU exploring and collecting items which are then retrieved by Skies when you select he option in the menu to redock pinta’s ship. Kinda similar to the way FFVIII on playstation linked to chocobo world on pocketstation.

          • http://techgage.com/ Rob Williams

            You might want to Google around a bit. I’ve found a VMU explorer and also some emulators, but it looks like a lot of them haven’t been updated in a while (as in, up to 10 years). The VMU editor would allow you to edit variables and resave the file I think, but it might be more of an advanced tool. I am not sure exactly why VMU players wouldn’t be a part of DC emulators. I remember thinking about looking into it before for Sonic Adventure, but never actually did.

          • Robert

            Alrighty, Thanks a bunch. Might look into it later, not too terribly important it would just be nice to find a few extra moonberries lol. anyways, back to playing!

  • Mark Powell

    Thinking of buying a dreamcast controller and vmu along with a usb adapter. Does anyone know if the vmu will work? Cheers

    • http://techgage.com/ Rob Williams

      There’s a USB adapter for the DC controller? Either way, I can’t imagine you’d be able to use the real VMU as normal. I have doubts it’d even powerup. That’d be an amazing feature for nullDC to implement…

      • Mark Powell
        • http://techgage.com/ Rob Williams

          I’ve searched for solutions like that in the past, but always came up empty for some reason. Thanks a ton for the link. Good to know on the GameCube side as well. I bought an N64 gamepad for the PC because that controller really doesn’t carry over too well to any other. Same would definitely apply to the GameCube controller.

          • Mark Powell

            No problem. I was thinking about getting an n64controller after this one. Although the xbox controller works well for the dreamcast, it just doesn’t feel the same. If I go for it, I’ll post back on here with the results. Have you tried demul emulator? I see its still being worked on.

          • http://techgage.com/ Rob Williams

            I can’t get used to the Dreamcast controller like I used to… I just find it uncomfortable. The N64 one is the exact same way, but it’s truly required to play those games sufficiently, mostly because of the C buttons.

            DEMUL is a great emulator as well. The VMU save files are compatible with both emulators, so you could move your saves back and forth if you wanted to.

          • Mark Powell

            That’s really good to know. I’ll do a little experimenting over the next couple of days, see which games work better on each. The n64 was a strange one, it’s like it was designed to be played by that guy with the mutant in his chest from total recall. Never quite understood the 3 handles? I agree it is needed though, I struggled to map golden eye to the xbox controller.

          • http://techgage.com/ Rob Williams

            DEMUL is required for any game that uses WinCE:

            http://segaretro.org/Windows_CE

            I stick to nullDC for the most part, but use DEMUL when I need to. I might end up moving to DEMUL entirely at some point though, given it still has active development.

            I agree on the N64 controller. Holding it today… it’s just seriously uncomfortable, and too tight. It’s a truly ridiculous design, and looking back, it’s REALLY rough not having a second analog stick for viewing.

          • Mark Powell

            Thanks for that. I had no idea, funny the things I’ve learnt about the dreamcast in the last couple of days. Its really giving me massive respect for Sega, whilst making me sad that the dreamcast was really the last console I actually cared about. There’s something that just one day changed, being able to free aim, no more turn in the direction of the bad guy and click. And the thought of using essentially a D-pad to aim seems so backward. Especially as Sony had already made the dual shock controller. I never used one but a pants looking controller was the Saturn’s 3d one. Looked like a squashed blob with buttons

          • http://techgage.com/ Rob Williams

            The Dreamcast is an incredible console. The fact that it was the first to offer a Web browser is pretty damned cool, but more than that to me is the fact that you could download saved games direct to the VMU. I used that ability a couple of times, either to replace a save I lost, or to check someone else’s saved game out. The console itself was just nice to look at, too. A good size, clean, and very modern-looking. I mean compare the look of it to the original Xbox… geez. Even the PS2 was far uglier, in my opinion. Then we have amazing technical feats like what we saw with Shenmue.

            The Dreamcast died way, WAY too soon.

          • Mark Powell

            I read an article with one of Sega’s marketing people the other day, he was saying how much effort they put into it cosmetically, and you’re right, it looks great, only Nintendo have matched the style of that console. He also said how they were footing the bill for the online side. Which for a company that needed the money shows a real dedication to the fans, but it looks like it lost in the same way betamax did. I think it was released too late to compete with n64 and too early for PlayStation and it’s dvd capabilities. I really would have liked to have seen another 3 years of development. I bet we would have seen some cracking titles. Shenmue 3 perhaps? I might get an old one on ebay, found out you can hard wire an old ide hdd to it. Just doing my research at the mo.

          • http://techgage.com/ Rob Williams

            I still have my original Dreamcast, but older consoles on newer displays hurts my eyes too much, and I refuse to ever touch a CRT again. So, I just stick to the PC for old-school gaming. I don’t need games to look 1:1 with their original like some do… I welcome extra crispness ;-)

            Have you ever tried out ePSXe? It’s also a great disc emulator.

          • Mark Powell

            Yeah I have it on my tablet too. I keep meaning to one day finish vagrant story. The ps1 was another classic . Some amazing games on that too. I see nulldc has come to android aswell. Haven’t tried it yet. Reicast I think it’s called. I’ve just ordered two dreamcast, I’m hoping to get one working out the two, and keep the other to mod. See if I can get a crisper look with the vga mod. Can’t believe it’s been 15 years, I got my first job to pay for that console haha. Thinking of old monitors and tvs. Do you know if the light guns work on led tvs

          • http://techgage.com/ Rob Williams

            I installed Reicast but haven’t given it a try yet. Given the fact it has a 4.0 rating on Google Play, I reckon it must be fairly refined, so I’ll check it out soon. Also, since the VMUs are interchangeable between nullDC and DEMUL, I am guessing they’d also be usable with Reicast as well.

            I agree on PlayStation. Dreamcast definitely places above it in terms of my most-loved consoles, though (it might be my most-loved in general… just a toss-up between that and the NES and SNES). It has so many classics though. Always been a fan of the Ridge Racer series, and that console had a billion of them.

            LEDs are no good for lightguns, unfortunately. It’s too bad they didn’t use a solution like what the Kinect uses, because in that instance, the display wouldn’t matter.

          • Mark Powell

            I think reicast was made by the nulldc bunch. That would be great if the vmu data is transferable. I can’t see why it wouldn’t be. I missed out on the NES, i borrowed a snes and used zsnes and snes9x on a pc i had ages ago. I was a big fan of Zelda growing up. My playstation came with ridgeracer, have you tried the new one on steam? I think its free to play which puts me off. Shame about the light guns, I suppose they work off the scan lines?

          • http://techgage.com/ Rob Williams

            I was lucky to have a mom growing up that loved gaming as much as I did, so we had most of the consoles to come out, with some exceptions (didn’t have a Sega CD or Saturn, or even my own PlayStation for quite a while). So I ended up getting into emulation pretty early. If I recall, the first emulator I used was Nesticle, an NES emulator (as you could probably guess). Had quite a memorable name.

            I think I installed that Ridge Racer but ended up deleting it once I remembered how much I hate F2P games. The RR to come out before that, Unbounded, was quite fun. Have you tried that one?

          • Mark Powell

            You lucky SOB. I have to admit that I’ve actually only played the first two or three on playstation. The last one I played had a Japanese woman in white on the cover I think? I just went to see if unbounded was in the steam sale, but the steam sales finished. Astheticaly it looks good though. Going back to the vmus, I remember Quake 3 you could download mazes, which would give you a higher max ammo or health etc when completed. Do you ever go back to any NES or SNES games? I played Streets of Rage 2 last night with the missus.

          • http://techgage.com/ Rob Williams

            Ridge Racer is a great series, but given the fact that there have been SO many titles, some of them aren’t so hot. RR6 for the Xbox 360 was great, but RR7 for the PS3 wasn’t too different. My favorite on the PSone, possibly, was actually Rage Racer.

            I don’t actually remember that with Quake 3. I do own that game though for the DC… I kind of hated that version because the weapons you picked up weren’t actually rendered in the game… they were just icons. If I recall, Unreal Tournament for the same console didn’t have that problem.

            And yes, I still play a lot of old consoles quite a bit. I played through both Dragon Warrior and Faxanadu (NES) last year on my NVIDIA SHIELD, and am currently working through Secret of Evermore (SNES). Edit: I guess it was Willow I completed on the NES along with Dragon Warrior. Faxanadu I am still working through.

          • Mark Powell

            I also had no idea you could download saves, that console really kicks ass

          • http://techgage.com/ Rob Williams

            I -think- you could also download unique games to the VMU as well, to take with you. The console really was ahead of its time, the VMU itself was just plain cool. It’s hard to believe we’re talking about a console that came out literally FIFTEEN years ago.

  • Pottypie

    Hey, I’ve got the emulator working, but I don’t seem to have any memory card slots. How do I make them?

    • http://techgage.com/ Rob Williams

      You need to go into the controller configuration and add them. They’re effectively treated as add-ons.

      • Pottypie

        Thanks, I realized I’d misread what you said and had selected the wrong type of slot.

        • http://techgage.com/ Rob Williams

          Oh nice, glad you got it sorted!

  • Da Boz

    Hey, not sure if this is still active but I’m in some desperate need of assistance, I have a logitech controller…kind of old model, which the nulldc won’t let me configure on its own, it sees it but doesn’t respond to it. So, I looked up what to do for that and found xpadder, and configured that to work with the keys as instructed by a tutorial video. after all this bull I thought I finally got it going, as nulldc responded to the controller. Only when I boot up sonic adventure, which works fine, the controller buttons do nothing beyond the tv specifications window. The controller works for that…but not for the game AT ALL. So I’m completely frustrated byt this as it’s taken my forever just to figure out how to get the emulator to see the controller sand it still doesn’t work…is there ANYTHING i can do for this or should I just invest n some other controller? If so, please let me know if a model it’ll respond too without having to do all this stuff first.

      Just to make absolute sure: The gamepad works just fine in the DC system menu (the blue one with four icons), but dies as soon as the game is loaded? That is extremely odd. The first thing I’d do is test out another controller plugin, if one exists. Or perhaps better still, give DEMUL a try instead. Since writing this article (and really, only recently), I’ve come to like DEMUL a lot more than nullDC, as it’s been more stable and has less graphical glitches. You might have to carry over the controller plugin from nullDC to get it to work in DEMUL, though. If you want me to email you an already-configured DEMUL, let me know.

        Wow! I didn’t expect a response to quickly, thank you for that!

        But yes, the initial menu thing works but once the actual game begins from there (the intro, sonic trying to kill that robot thing…) it doesn’t respond to the controller, no matter what i press on it.

        There is a second port which I’ll try, but to be safe yes I would appreciate being e-mailed an alternative emulator, as I’m about fed up with this one *laughs* honestly, I must have watched at least 10 tutorials just to get this far with it…I’m not sure how to carry over the controller plugin, this all makes me feel really stupid as I must have spent at least 2 hours on it trying to figure this all out with nothing to show for it.

        But again thank you for getting back to me so promptly and considerately, most forums I come across where people ask these sorts of things the people are really rude like everyone should know how to do this stuff. Oh and my e-mail is da_boz_tiger@yahoo.com

          E-mail en route. I’d recommend removing your email address here.

          Have you tried another game? I am wondering if it’s just limited to that one for some reason. Though assuming you are talking about SA1 or SA2, I’ve had no problem with them in the past.

            Allrighty…so thank you sending that, I can get as far as getting the controller to work but have no idea how to load the game itself, I got as far as the dreamcast select screen, games, then asks for me to load a disc or game or whatever…no idea how to do it,.

          • http://techgage.com/ Rob Williams

            You need to click on the Config menu and then GD-ROM. That should bring up a prompt to let you select the disc. Once you do, you can hit OK, and then File > Run Dreamcast.

            …I’m about ready to have a meltodown

            it’s looking for cdh files, it doesn’t see the one I have as it’s a cdi, and I tried finding those but i only get cdis.

          • http://techgage.com/ Rob Williams

            When selecting a disc image, it should say “All supported formats” in the bottom-right drop-down. Then it should show CDI, MDS, CCD, NRG, GDI and CUE as supported files.

            Was CDH a typo?

            What game are you trying to run?

          • Da Boz

            I fiigured it out, I imagined I had something set incorectly, I had the gdr-rom plugin set to gdrCDH, hence the issue with the file selection, I fixed that, then it could see the rom and it worked just fine, joypad and all.

            Thank you so much for your patience and assistance with this, I’ve been waiting to play sonic adventure15+ years so it’s a big deal for me, not half bad…reminds me of sonic heroes, least the first level.

            But again, thank you very much for your help, that was awesome I probably never would’ve figured it out.

          • http://techgage.com/ Rob Williams

            I’m glad you got it sorted out! SA is probably my favorite game on the Dreamcast. The camera angles leave a bit to be desired nowadays, but the levels and music more than make up for it.

            Have fun!

            Heyo, me again, I have one last inquiry I didn’t get around to asking about yesterday, how do I save my progress on the games? I tried looking this up myself but only managed to find something about vms and this version of demul doesn’t appear to have that. I tried the ‘save state’ thing too, as that’s worked for me in the past with emulators but doesn’t do anything for this one. I’m sorry to be such a pest, I’m pretty sure this is my last issue with this though!

          • http://techgage.com/ Rob Williams

            I gave you my exact install of DEMUL so you should already have some VMUs (make sure the plugin paths are all correct). They’re located in the ‘memsaves’ folder and are called vms00.bin and vms01.bin. I’d test to make sure they work by using the GD-ROM option to eject the disc, and then start the Dreamcast to go to the system menu. Then you should see the VMUs in there (ready to format and call your own). If not, some path is off.
