From the title, Yes, I cant run ANY gba rom using 3 in 1. I tried load them in PSRAM still doesn't work. Then, load in NOR, still no shows. I'm using R4-YSmenu, Akaio and Gba_ExpLoader. All of them loads fine but then it only shows the Gameboy logo without the Nintendo logo. Signs that the cart is not inserted. But how come? All of the software detects my 3 in 1, the rumble works fine, Expansion Ram works too, but no GBA. I took them off and inserted it back, the NOR with the game is still there. It doesn't look like a contact problem. I tried loading the 3 in 1 without the slot 1. It only shows that the DS OPTION cart is inserted. I cant open the NOR using DS firmware. What should I do?
