Playing GBA ROMS on NDS or NDSi

I'd like to know how I can play the GBA ROMS on my NDS ( I have a R4 card & acekard2)?
If anyone can point me in the right direction i'd be grateful.

You need an iPlayer,A slot-2 flashcard for gba,or EZ Flash 3-in-1(I think thats what its called)

To play GBA roms on a DS lite you will need EZ Flash V 3 in 1. It fits into the GBA Slot and works with your Slot-1 device like R4DS.You can't play GBA roms on a phat DS or DSi.

The EZFlash 3in1 comes in a regular GBA-sized cart for use in a Phat or an actual GBA, and the iPlayer can also be used for GBA emulation on any DS.

Yes. My GBA-Sized EZFlash 3 in 1 works just fine in my DS Phat and a CycloDS Evolution slot 1 card :)
