Yes you can
No, if the guitar is wireless, probably, but then if you want to use a GH2 guitar and play it on the PS3, then it is not possible because the controller connections are different. I hope this was the answer you wanted.

You CANT play PS2 games on your PSP. You can however play PS1 games. PS its "custom FIRMWARE instead of Software]
Guitar Hero 1 was a PS2 release. GH2 and 3 are only available on XBox 360.
Goofy Goober Rock did not appear on Guitar Hero 3 for the PS2. It was a custom song that somebody put in their game.
No Nintendo DS games were not designed to play on the PS2 and the PS2 can not play them
No because each guitar has its own radio frequency that connects to the adapter. However, if you did some modding to the guitar it could happen.
No.But PS3 can play PS2 games and PS2 can play PS1 games.
yes the PS2 will play DVDs
