Hello, I just won a DS Lite, although I have a GBA SP and I have a 256MB memory (for GBA SP) with a card reader/writer that connects to USB. I have been playing gba games, and I have 2000 games on 2 dvd. I was happy with my GBA SP, but now things getting complex. I can sell GBA SP + card + reader, then how can I play my GBA SP roms on DS Lite? Is there a solution that I can play both the GBA SP roms + DS Lite Roms? Thanks.
You best option is probably to get a good slot-1 card such as the R4DS or CycloDS and then get the EZ Flash 3-1 Expansion pack for GBA games. But there are lots of different devices and combinations of those devices so you might want to have a look around.
Yes, using the M3 MiniSD you can, but it will stick out from the bottom of your DS Lite. Using a MicroSD you can get an M3 Lite which won't stick out. EDIT: How'd I manage that? My post has appeared above yours on my screen :s Does it look like this for you/anyone else?
If you have a flashcart, yes, the ones that work for GBA work for the DS, they just stick out. As mr. Hankey recommended, the M3 MiniSD is quite good, but if you already have a good cart I'd save the money...
