GBA on DS

Hey all,
Sorry if this has been posted but I can't find the answer anywhere. First off all, absolute noob at this and have recently gained an R4 which I use mainly for emulation. I currently am playing with NES, SNES, Genesis and GBC emulation. One thing that I can't find much info on though is GBA emulation. Is this possible with a Slot 1 card or do I need something for my GBA slot on my DS Lite??Thanks in advance :)

No, get an EZ FLASH 3 in 1(slot 2). Cheapest bet.

If you are an absolute noob at the R4, why not gather more information and learn more about it before buying it? And yeah, you need a slot-2 device in order to play GBA games on the DS, which stinks in my opinion.
