GBA games on DSi?

I was reading random stuff about GBA games on the DS? Can it work on the DSi? How do I do this?

Buy SUPERCARD DSTWO simplest for your intention. There's a GBA emulator for R4, but glitchy since the R4's spec isn't capable.

Hardware wise, dsi does NOT support gba or have a gba slot officially. you can do what the other guy said if you must want to play gba on it.....or get a classic nds.

Thanks! I just bought a supercard 2
