I've been looking around for GBA Flashcarts (that play GBA roms, not DS roms) for DS original, and I can unfortunately only find ones for the DS Lite. The EZ 3 in 1 's I've found seem to only fit into DS Lite, and I can't seem to find any that fit into the original "fat" DS. I prefer the old DS due to the shoulder buttons working with more consistency, so it'd be a great help if someone could tell me which flash carts fit my purpose, and where I could possibly purchase it. tl;dr: Which GBA flash carts (that play GBA roms) can be used on a DS Fat and where can I purchase them. Thanks much!
