quantum 3d  quicksilverII off road thunder

Just wanted to say sorry for posting same topic twice. i didnt know that if someone clicked on general topic.they could  read tech talk post with out clicking on it.

maybe its just the firmware version on the Xilinx IC

i dont know iam complete idiot on chips and cards.just was told by a ex midway tech that hydro and off road thunder arcade games had this certian card with certian chip wouldnt play without it.and it wont tried several different ones. also told me good luck on finding one. maybe other games have it i just dont know what they were.

I know somebody with the same problem. He's got a quicksilverII system and the original board just died for some reason.
What exactly asks for this lock-out chip - the game or the motherboard? If it's the motherboard maybe we can change just the motherboard?
Is there a possibillity that this chip is a flash and it could be reflashed?

as far as i know the 6pin header on the card is for flashing/ programming the chip.

I've never used a programmer before. Is there a difference between them? Or I just need the correct head for it?
