rygar help

Question

Hi i recently got myself a japanese rygar pcb

pcb a side.jpg[ATTACH=CONFIG]119187[/ATTACH]

It was sold as working i plugged it all in turned it on loaded up fine i grounded the coin1 button(as it wasn't connected to a switch yet)

it played the into scene and then glitched out( all graphics disappeared) and now when i start it i cant even coin it up anymore wondered if it was a voltage issue and i notice when the demo plays it has no characters in it

i was a bit unsure about the harness it looked a bit old and only used 2 of the bottom 5 pins used for 5 volts and all in all just dosen't look to nice.

I brought a new 18 pin connector so i might make a new harness with all the 5 volt connections

Although i did go over the board with the multi meter and all the rom chips seem to be getting just over 5 volts

any help would be much appreciated
