No unfortunately the instruments for rockbands are platform specific.
yes
NO
No, but all 360 instruments will work on the PS2 with Guitar Hero: Aerosmith and newer (except for drum kits on GH:A of course).
Rock Band games on PS2 only support PS2-style guitars and PS2/3 Rock Band guitars and drum kits. Guitar Hero: Aerosmith and newer on PS2 support all instruments from all consoles that the games have note charts for (so no drums on GH:Aerosmith but 360 and PS3 drums work on all full-band GH games).
No. Rock Band games on all systems generally only support controllers for the system being played on. However, PS2 and PS3 Rock Band instruments are cross-compatible.
The rock band controllers will work for both PS2 & PS3.
It does if you get it as a bundle with all the instruments
yes, the ps2 rock band controllers are actually ps3 controllers but they are ps2 compatible
Use the Hub
yes no problem Buddy
the ps2 kramer (GH3) and the guitar hero 1&2 guitars work for ps2 rock band games
Sure the PS2 game works
