This is Gon-ta's Great Adventure for the Game Boy. I have confirmed that it works for a few minutes from the title screen on the Game Boy Advance. I was able to save during the test, but I cannot guarantee it because it is an old cartridge. For Game Boy cartridges, I can handle up to 24 cartridges in a bundle. I can discount 200 yen for combined shipping, so please contact me through the bundle request.
