there wouldn't be PS1 codes on a ps2 gameshark but since ps1 games work on ps2 you might be able to download ps1 cheats onto ps2 gameshark but it is doughtful since ps1 and ps2 gamesharks and gameshark codes are probably differant format
Im pretty sure u can. Im 95% sure since the ps2 can play ps1 games. U would have to download the codes though
sadly not. although playstation 1 games will work on a playstation two console. the playstation two games feature software that the PS1 is not capable of processing rendering them unplayable on older consoles
no the new codes are written in a different language.
No, it doesn't I have tried it. But the stick you can use in PS2 U know that :)
no you can not
Yes.
yes
the larger ps2 you can ...yes not the slim ps2
yes, the ps1 controllers are dualshock, and the ps2 are dualshock2, so it may not be as good overall as a ps2 controller, but it should work
Yes ou can, but only for PS1 games.
Any PS2 wireless controller should be able to work on the PS1. A PS3 wireless controller will definitely not work on the PS2 and PS1, because they use Bluetooth as their wireless technology, whereas wireless PS2 controllers use 2.4GHz as wireless technology.
