Nope. The first 2 Guitar Heroes were released only for non-Nintendo systems. The discs aren't compatable.
no
There is a Guitar Hero for Wii, but it isn't exclusive to Wii.
For wii you don't need the guitar, you can just use the controller.
yes
According to wikipedia you can use a wii remote plus with guitar hero. http://en.wikipedia.org/wiki/Wii_MotionPlus
Yes, they are. As long as they are on the same system.
No, you can't use your Rock Band Wii guitar for guitar hero or vice versa. You can't use rock band guitars on guitar hero...but we use our wii guitar hero guitars for both rock band and of course guitar hero. You cannot switch out drum sets. We have had to buy both sets, rock band and guitar hero.
when rock band 2 and guitar hero 4 come out, anyone who has rock band for any system EXCEPT wii will be able to use their rock band stuff for guitar hero, but u can't use guitarhero controllers for rock band
The Guitar Hero 3 guitar is not compatible with Rock Band on the Wii. And the Rock Band guitar is not compatible with Guitar Hero 3. You can try anyways but I'm pretty sure they don't work.
You can't.
No, not for Guitar Hero (Wii) nor Rock Band (Wii).
yes you can but you have to buy it on wii or Nintendo
