Several years ago, I bought in a local game shop what to my knowledge back then was a multigame gba cart. I now know that it is probably a flashcart loaded with some roms. When I figured this out, I started to wonder if I could be able to use it to play my own backups. But it has no expandable memory and it didn't come with any adapter to read it from the pc, so I thought there was no way I could edit it. But I've started to see tools for slot 1 ds flashcards (I have a Cyclo) that manage current flashcards like the EZ 3in1. Do you guys know if there's any piece of software I could use to get my own games into this cart?
