Why is it when large companies begin right-ing their wrongs, they don’t usually take long to settle back to their old ways? When Sony released their Playstation 3 80GB edition, it was found that the emulation hardware was non-existent, and instead, it would all be software-based. This should be a non-issue to the consumer, but it apparently causes a lot of inconsistencies of stability from title to title.
To help you figure out if your favorite games have known issues, Sony has updated their compatibility search-list for both the 60GB and 80GB models. Depending on which model you choose, the results could be different. Overall, there are far less problems with the 60GB model, although they do exist. The moral of this story? If you are planning to pick up a PS3 and care a lot about backwards-compatibility, run out and pick up the 60GB model before they go extinct.
As we learned during E3, the new 80 GB PS3 does have backwards compatibility issues. All future PS3 models will also have similar BC issues as they’ll use the less expensive software emulation program instead of the PS2 native hardware which is currently in the 60GB model.
