I was loaned this item and it already has a GBA, SNES, NES, and DS emulator with some games installed. I wanted to get rid of some of them but don't know how to safely. Also, I was wondering if the GBA emulator will be able to run GB and GBC or if I need separate ones for both of those. Finally, I don't know how to put ROMs onto this thing. I assume I need a computer, obviously, but what else? Some type of converter or something? Running this on a 3DS, if that matters. Thanks.
