Virtua Fighter Issue

[Pizpiz80]

So my roommate has a Virtua Fighter arcade game that he got in a trade. We got it home to the house and it doesn't work. He's not a tech savvy guy so I figured I'd help him out. Well the main issue is when the game starts nothing happens. I decided to run the tests that are available through pushing a button behind the coin door. The CRT tests passed and everything is good there. I ran the memory test and it said that 12 & 16 are bad. Then I ran an IC test and 57 is Bad/Good, 68 is Bad/Good, and 66 is Bad/Bad.
How do I help my roommate out and get this great game working for him? Hopefully it's something I can fix.

Thanks
