well I do have a GBA, I don't have a serial port cable (I just check what it looked like and nnnope), I wouldn't even know where to find a gba link cable in 2026 lol, the rest sounds even further from my newbie's league.
I know about a cartridge for NDS that have a sd card in it but I don't think there's a way to use a homebrew app with these, that could also access the GBA slot, is there? Anyway the shipping would still be a problem.
Using this for another quick ask: do we have in 2026 ways to dump GBA cartridges for cheap (<100€) in Europe?
I know a couple years ago there were some cool emulator/dumpers in cool plastic boxes like the GB operator, but they're apparently all...
