no, you cannot play ps2 games and yes you can play nes games by downloading a nes emulator.

dang asddasit your so fast at replying

thanks for the help,

now what if i just want to play nes and 64 games, do i need to upgrade and downgrade or can i just DL the emulators, and if so where can i get the emulators and roms, thanks

You need to downgrade in order to use any homebrew appz ( nes, and n64 emulator)
