How can you tell?
are you looking for one bud ?
that's correct. Based on the lack of the U116 PAL that was originally a Zing Zing Zip.
I was just guessing! According to twistedsymphony's reference codes it is a Eight Forces/Zing Zing Zip.
not impossible, but definitely ugly. It's requires doubling the RAM and adding sprite banking logic. In my video above you can see the PCB I built to add the sprite banking logic. For the extra RAM Zombie raid is the only other PCB that has spots for it, otherwise you'd have to build another custom sub-board or stack ram chips to do it.
I have access to THREE Zombie Raid full arcade machines, but I don't want them and can't bring myself to pull the boards out. $900 for the three... man, wife would kill me if I did it...Option 2 would be cool, but option 1 already covers the 4-chip games I'm most interested in. I would prefer 2 but would be happy with 1.
Edit: Which one of you guys got that Zombie Raid on Ebay
Thanks, I have a JJS and I thought it was a bootleg, but I need to look at it again, as it might be a conversion and I never thought about it. If it's a conversion that would be great, b/c I could use it for the multi!

Thank you Alex, only if it's cheap! I was passing on ZR for $100 not to long ago and I've never even heard of the other games. No way I'm paying $500 for a $100 game just to make it a multi of games I already own!
real JJS boards have a sub-board for the graphics ROMs:
