Title: TwinFamicom issue - white lines
Post by: WF72 on December 26, 2015, 03:56:57 pm
So I bought a twin Famicom for myself as a Christmas present, and yesterday it worked like a charm. But today, whenever I try to play a cart game there are white lines all across the screen!
I don't know what to do. The disk mode still plays perfect
I cleaned the cartridge slot, but no improvement
What do
EDIT
I Looked inside the cartridge slot, and it looks like the pin on the top right is bent inwards. Is this an issue?
What does this pin do?

Try cleaning the pins on the cart and inserting/removing the cart a few times. This can happen to ANY Famicom and occurs when one of the CHR data lines isn't connected properly.
