Hmmm, heard of any BC problems with the Guitar Hero Series (at least GHLOR and GHWT)? Those could be my main concern as far as compatibility goes. As for the guitar controller, allied brands blog I'm getting a new Kiss Axe guitar anyways so no problems there
I'm well aware of the chip/software emulation issues but I just didn't wanna look up for an older 60GB console. Guess I'll do a search anyway and see if I find a decent one just in case.
