Jurassic Park
Data East, 1993Just picked up the 2 chad eprom from John wart. Put in game as instructed with notches. On power up I get GI and one T. rex roar and nothing else. No display either. Contacted John but have not heard back. Put old Roms back in and it's perfect Any ideas?
When I got mine, I got asked this question:
"Data East ran two configurations for the display board and some had 1x display rom and some had 2x.
The new code is burnt on to 1x rom chip, so if you currently have two on your display board, then you will have to change a jumper on the board for the new rom. I can provide instructions for this if we need to do it."
Did you confirm this?
Quoted from rooky79:a pair should have come. One for the display board and one at the board in the back box
Thx. My post mentions this 
one for mpu one for display. Thx for ideas though. Thinking now it's corrupt. Sucks cause picking up game Friday. Took a week to get them
John had me check display Rom and it comes up 6.0 with old game rom in. So guessing new rom was corrupt. He already mailed new rom out.
Mate you'll love it when you get it in. Completely turns the way you play upside down.
Multi ball is really hard to get as you're not spoon fed it and the modes give you a reason to play for points instead of stacking them for system failure
It kicks my arse now and can barely crack 400 mill
