Yes. You have to put it on different then lite's area
Yes, there is another thing in the box to use instead of the one that is in already. Just read the directions.
Yes, you can play all Nintendo DS games on a DS Lite, even play Gameboy games. However, some DS Lite GBA Slot packs don't fit in the Original DS.
Yes, if you buy the entire set (it comes in a small box...with Axel Steel on the cover - in reference of On Tour.) then there will be a converter in it that allows people using the original Nintendo to play Guitar Hero. This works for both Guitar Hero: On Tour, and Guitar Hero: Decades. ;)
Yes. The Guitar is compatible with both guitar hero 2 and 3. Also, the guitar hero guitar on xbox 360 is compatible with rock band for xbox 360.
Yes it is compatible with GH 5.
The current Guitar Hero games out for Nintendo DS and Nintendo DS Lite will NOT work in the Nintendo DSi. We can only hope that there will be some decision within the Guitar Hero Headquarters that will cause them to come out with a new Guitar Hero game compatible with the new Nintendo DSi. A Solution (Maybe): If we're lucky the Guitar Hero Company will create a Guitar Hero game that can be downloaded from the Nintendo DSi Store. Therefore, they may release some sort of device (key pad) that hooks into the DS Slot. It would be awkward but it would be better than nothing, correct?
The Guitar Hero III guitar is completely compatible with Guitar Hero: World Tour provided you're still using it with the Wii.
