Hi. I just wanted to test the demo on my spouses GBA SP and EZ-FLASH IV Card and i just get a blank white screen. Do you know any solution? I will also try with GB USB Smart Card.
We haven't used an EZ-Flash IV Card, but we have used our Analogue Pocket, Everdrive, and an Inside Gadgets card. It should boot up with your cart. Have you had issues with any other games and that cart?
