My makerbuino has been working fine until I accidentally left it on in the game menu section for about 1 hour.
When i realised it was left on, the game menu had become a mess of random pixels moving around. I tried to do the C button reset multiple times but now the game menu is a black screen.
All the games work fine though, if i navigate blindly to them.
I think something happened to the SD card, like it got corrupted or something. Maybe it can be fixed by reflashing the sd card?
Never mind, the problem has been solved. I think it was the speaker wire that was interfering with the connections in the screen, because when I accidentally snapped off and resoldered the speaker wires, the game menu was working again.
