Will Guitar Hero 1,2, Encore, and 3 for PS2 work on the PS3?

May be...

I am planning on purchasing a PS3 tommorrow and was wondering if my PS2 versions of Guitar Hero will work on my PS3? If you have any TRUE!!!! answers about this please please PLEASE tell me! Thank you.

straight up no lie...they do work...but you'll have to buy and adapter for your ps2 guitar...which will have some glitches on the ps3 for example pull offs and hammer ons won't work...you have to strum every note no exception, and ps3 wireless guitar that comes with guitar hero 3 doesnt work for them but i heard the guitars sold seperatly will...that part im not sure on cuz i haven't bought another guitar...but i have a ps3 guitar and a ps2 guitar and since i have ps3 i dont even play the ps2 guitar heros anymore simply because of the glitches...but if you want to find out for yourself the adapter is sold at gamestop for sure and its either 10 or 15 bucks
