Mortal kombat 4 Help...Faulty Board??

[SUPER_SSII_TURBO]

Hi I have just put...or attempted to...put a mortal kombat 4 pcb in my street fighter II cabinet...basically with the mortal kombats and street fighters, the only only wiring differences is the kick harness, se easch requires their own...but that is only for the 3 additional kick buttons....

Anyway here is whats going on...(i dont have the kick harness yet for the mk4 board) i plug in the board all the roms check and are fine...but the standard buttons that should be working(normal jamma boards are 3 button based) are not working...plus my screen gets waves in it...the street fighter board runs flawlessly whith this monitor..and it should not make a diffenrence...its a 25 in. standard res monitor...which is what both these games originally played on...any help would be great as i just spend 200.00 on this PCB board. and im lost
thanks

Maybe the 5V adjustment on your power supply.   Some boards require more power then others and can drag down the 5V if not adjusted.
