Do some DS games not work in a DSi?

[ohsnap!]

I have heard rumors about the DSi and some Mario games. For example: Mario and Luigi: Partners in Time does NOT work with the DSi!

So I want to find out which games, and if it's true.

All DS games work in the DSi. Though features that used the GBA slot won't work, but that's not that major.

Games like Guitar Hero that need that GBA slot won't work. You can't use DS rumble paks either, since they use that slot as well.
