my board broke, one of the contacts lifted. (Guess ill be ordering another one)

It still isnt working for me, not sure what im doing wrong now either. But everytime i wire up the cartridge port, i get completely no signal, even when i toggle the swith. i will update you as i figure out the problem

i figured it out. i had to remove j9?

Which jumper (or zero ohm resistor) is it that needs to be removed? Is it the "R5" jumper lead?

i have the same problem, and i have the exact same flashback 2 motherboard as you. in my opinion, it might be the jumper wires, but im not sure if i am wiring the jumper wires correctly; which is why you might have the same problem?
