Problem Snow Bros bootleg

[AlexK]

Hi,
Wanted to start my Snow Bros bootleg...RAM OK, Rom OK but it says coinerror?
What can cause this Problem?

either a stuck coin switch if your testing it in a cab,or one of the input lines could have gone bad,I had this once on a board and temp lifting the leg of one of the resistors on that line,enabled the board to boot

Thanks...it must be on the PCB...have tested many other PCB's and no problems on the coinswitch...it's a bit weird because i have this problem also on a second Snow Bros PCB.

could be a non standard pinout,you could try disconnecting everything except the power and video and see if they boot then
