I have two GBA SP, both model AGS-001. They both work with all types of cartridges (GB, GBC, and GBA) normally. I made the purchase of two Supercard Micro SD, only in one of my GBA SP does not work. The two Supercards work normally on the other GBA SP. Has anyone ever been through this problem or can you tell me why this is happening? I inform you that the two Supercad is in the last version of firmware, v1.85. It follows image showing the screen of GBA SP that is not accepting the Supercard, and how to put a classic GB cartridge, with the nintendo logo in black, as if it gave error in the cartridge.
Thank you from now on
