Above the U4 ROM, the zero ohm resistor at jumper position "X" needs to be in the "W" position.
i.e. X needs to be vacant, W needs to be jumpered.

Quoted from billsgto:Thank you, so I can just desolder that resistor and move it up to 'W'?
Yes, desolder it and move it up. With X currently being jumpered, only half of that U4 ROM is accessible so you're going to be missing speech/sound effects and it could possibly be causing your problem.
