I've been working on my Tron MCR power board for some time now and finally fixed it to the point where I get +5 and +12 adjustable by the pots. Board is capped, and many other parts replaced like voltage regulators and some transistors.
However, when I boot the game, I get a screen of garbage, and if I wait long enough, the game reboots and eventually works. Manually cycling power a couple times sometimes does the trick.
I have a Satan's Hollow, and when I swap in that power board, Tron boots immediately without issue.
The +5 is set to around +5.1 on both boards.
I've been waiting to get this fixed before I install the SRAM (http://forums.arcade-museum.com/showthread.php?t=90255) and I see alot of other people have this problem.
Any ideas on what to check, or what causes this?
