My GB crashes when I press both the A and B buttons, I've tried several different game carts but the problem is persistent. Does any one know what the cause of this could be.
Can you explain in more detail?
I can try. I have an EMS64 with LSDJ on it, I recently replaced the battery, and when I press both the A and B buttons at the same time, whatever sound was playing continues to play and the buttons don't accept input (sometimes the screen gets garbled as well). I thought this was a problem with the EMS64, but I tried playing Pokemon Yellow and Silver and both had the same problem.
Sounds like we are going to have to up ur boy and check him over. I would start on the front PCB and examine all connections relating to the two buttons in question.
Can you trigger this problem with no cartridge inserted? What about pressing only one of the buttons but doing applying a fair bit of force?
