I'm in the process of getting a 2ds for my daughter and wanted to read up on flash carts. But jeez, it's so confusing between ds, dsi, 3ds, 2ds, then different types of games, etc. I have 10+ 1-2gb micro sd cards laying around so I know some work off that principal. But what is compatible on 2ds and would give me access to the most game types? It's sad, I can solder modchips for x360, LED light mods in controllers, hex editing, etc. But this damn DS is confusing as balls.
