There is a .gba->.nds converter tool out on the internet, but to run the converted roms you still need a slot2-device like EZ3in1. To run GBA-Roms on a DS without Slot2-Hardware isnt possible anyway.
Yeah i definitely recommend EzFlash3in1.. It worked well for me for a few months, but it was worth it
this doesn't go here...shouldn't this be technical help? BTW Dragonquester, what happen to yours, you say that like it broke...
lol it did break... lol I dont even know what happened... I played with it for like 4 months or around that time span, and one day I went to the flashcard menu, it wasnt loading up.. And ever since then, It never loads up
