I just purchased a PS3 80GB Backward Compatible for Gran Turismo 3 and 4

I have not played either as I chose to play on a family PC in highschool with Starcraft, Baldurs Gate 2 and Rainbow 6 Rogue Spear. Counter STrike 1.6 as well.

It works.

In PS3 not backward is possible to running too, but with restrictions....for example, gt4 higher res will crash or glitch the game.
