Can you play play station 1 games on play station 2? Can you also play xbox games on xbox 360? Thanks!
Yes, and yes.
yes and some but not all
Some, but not all of them.
Yes, you can, with some games (Such as Halo 2).
No not really.
PS2 is backward compatible with PS1, though, you will need to use a PS1 memory card to save your games. Xbox360 is only backward compatible with some of the library of Xbox. You can find a list of games it is compatible with at http://en.wikipedia.org/wiki/List_of_Xbox_games_compatible_with_Xbox_360
Some of them u can others are a no go
