GameSpot was recently able to take advantage of some extra time with the Playstation 3 and look into the console’s backward compatibility options. GameSpot wasn’t able to look at a lot of games, but they had enough time to look at a Playstation game, a Playstation 2 game, and a Playstation 2 game from a different region. The Playstation game tested was Battle Arena Toshinden 3, which seemed to work fine. Gran Turismo 4 also appeared to work normally on the Playstation 3, while the Japanese version of Kingdom Hearts 2 was locked out because of region restrictions. None of the games were enhanced in any way by the PS3, as expected. While the tests are interesting, they still don’t detail how Sony is achieving backward compatibility, and there is still no official list of incompatible games.
