What other systems can the R4DS play?

I have an R4 for my DS, and sadly it can't play GBA games, but then I wondered if it might be able to play other systems, like the GBC or the SNES. Can someone give me a list of other systems besides the DS, and how to run them?

With Lameboy, you can play GBC...really limited though, and it feels weird to play with only 2 buttons on your right..

Thanks for that Kamage. Your a legend.

See my "Emulators for DS" topic in the NDS Trading Station. List of all NDS emulators, basically all the other systems the NDS can run. Kamage, you know better.
