My Satan's Hollow now comes up with the following errors...

RAM Errors B2 F6
ROM Errors D2 D4

The RAMs appear to be 6116 (anyone got spares they can get me ASAP?). The ROMs are the 2 Free Play ROMs...

Any ideas beyond just re-burning the ROMs? Why would just these two go "bad"? Voltage seems to be about 5.5V
 
I doubt the ROMs are bad. The RAM errors are causing it to do more extensive checks, so then it finds the modified ROMs (because it is checksumming smaller blocks rather than the entire chip).
IIRC, B2 is the battery-backed RAM. Are your batteries good? Are you using a Dallas there? 5.5V is too high... that could put a Dallas into write-protect mode.

Thanks Matt.

There is no battery on the board. It was removed when I got it, and I never put one back... B2 is just a 6116.

BTW, I lowered the voltage slightly and the game came up. Thanks!
