There are homebrews for the wii to backup gba games and saves using a gba to gc link cable. There are computer programs that do the same with the use of a gamecube controller adapter. My question is are there any homebrews or programs that let you flash repro / bootleg gameboy carts? I'm not talking about carts designed specifically for flashing like the flash2advance or anything like that, I'm talking about if we can flash those cheap gba repro carts that we see on eBay similar to how the Joey Joebag can or the GBxCart RW.
