Guys, I've got this faulty GBA cheap in hope to repair it, but this problem I've never heard of. The system plays GB and GBC games like it should, but when I try to play GBA games, It loads the tiles ramdomly, making the screen garbled, very messed up. The sound is terrible as well (watch out, headphone users). The GBA carts play on other systems, as I have 1 AGS-101, 2 AGS-001, and 1 AGB-001 to test. Ez-Flash IV doesn't even boot on it, I get just a blank screen. I've got a video of it, so you can see what happens: Though, the mess is random. The screen where you should choose your save slot sometimes have a dying Mario (instead of the one swimming on the video). I thought of BIOS corruption, but the GAMEBOY logo from the boot up is OK, and GBC games work fine (tried the two aspect ratios as well). GBATemp, you're my only help! Thanks for your attention.
