Don't know what D9 is or does. The schematics don't tell you what each component does? If not then, I'd say just replace the burnt component, and hope for the best. I couldn't tell you if D9 is needed or not for the game to play.
Is the game all back together now? And what happens at start-up? Darrell said he has a couple of EVO CDR if you end up needing one. They will not open if you they are out of the machine (not powered). We use a straightened out paper clip to open them, just to verify the CD is actually in there.
EVO kits are not everyday finds, so lets hope all the software is there. These are fun games, basically their the Bally version of the I-Game. We've had Felix the Cat, Harvey Kormans Last Resort, 99 Bottles of Beer, Sunset Beach, and some luau one.
