I want to be able to run DS and GBA roms on my Nintendo DS lite, movies mp3 ect ect..Is this the best thing out right now or the m3?
DSX does not support GBA. For GBA, I would recommend an M3. If you have a DS Lite, I'd say get an M3 Lite, or if you have a normal DS get the M3 miniSD. Pro/Professional versions do not support GBA roms (over 32mbit or something like that, which is quite small. thats less than frogger!)
