i got a batrider pcb vers b and it works fine. only problem is, there is a orange line on the lower part of the screen always and i dont know what it is. its the only pcb i got with that kind of problem, all others are working damn fine. even my leo now, thanks that somebody could repair it.
What does your meter say when you measure 5v at the connector with this game running? Some Raizing and Psikyo PCBS are known to do strange things with strong +5v.
Nothing is wrong with your Batrider PCB, its your monitor. I bet its a tri-sync monitor, right? I get the same thing on one of mine. Works fine on regular 15khz monitors. Must be sometihng to do with how that monitor is splitting the combine sync from the board....at least thats my theory. My tri-sync also has problems syncing with a few other boards like NeoGeo and Cave PGM.
