So I bought a EZ Flash Jr today and got it home. When I put it in my Gameboy DMG_01, it won't boot. Just show up the nintendo logo (perfect no glitching) and then a emty screen with no sign of boot. I've try many times and also dust cleaning with the card and my device. Then I put the card into my old GBA SP and it worked perfectly. But I wan't to play it on the GB DMG real hard. I spend my last money in the card, so really panicking right in the moment, please help me ! Appriciate it much !
