Gba roms on nds flashcart

helloi bought an nds flashcart (Cyclo DS Evolution) a few weeks ago. I've installed some emulators on it with which you can play gb, gbc and snes roms on it, but i also want to play gba roms on it. can anybody tell me how i have to play gba roms on my nds flashcart? :'(

You can't. Slot-1 devices, such as the CycloDS Evolution, cannot play GBA games. You need to use a Slot-2 device to do so.

I can't believe how many times this question gets asked, search the forums before you post something.
