Comment on Midnight Resistance arcade cabinet restore by bmcphail

The original vinyl was left on, then gouges and holes filled with bondo then light sanding. Paint was Rust-oleum 300115 Satin Classic Navy which isn’t an exact match for the original, but certainly close enough.

Did you remove all the blue vinyl before painting it or did you just sand parts of the vinyl and paint over it? What blue is the paint?

FWIW, the Over Drive schematics show a 053246/053247 configuration (they’re available on arcarc). It’s usually the 053247 that fails.

I do. I helped code some of it

Thank you for your time and dedication on that game, your MCU simulation was almost perfect for years. Now is finally 100% emulated. Thank you to all people whose work on that project (you, Haze, Capsoff and Guru).

I’ve actually got an SCI board myself I haven’t fixed yet – the CPUs just constantly reset and it doesn’t even get far enough to display anything. I’ll put some time into fixing it eventually.

If the vertical lines are in ‘screen space’ (they don’t move with the sprites) then it’s probably the RAM on the lower board. If the lines move with the sprites, it’s probably the sprite mask ROMs that have failed.

Hi really impressed with your ability to fix these boards. I have an two sets of SCI boards which I believe is based on the same system z boards for Chase HQ, but it does seem to be laid out different.
Both video boards have a similar garphics issue with vertical lines, which searching the net it was suggested it could be the SRAM on the video board.
One CPU board again has the same issue with no road or car showing and the other CPU board just boots to garbage and probing the 68000 they just go through a reset cycle every few seconds.
Looks like I have a challenge ahead to try and get these sorted so appreciate what you have done and am trying to use that as a guide.

Have you done any SCI boards? Any tips also appreciated.

Thanks and keep up the good work.

I was wondering if you had some contact info available. I have a lot of boards that I would like to have you fix. Please let me know if it is possible to work with you and get some boards fixed. Thank you

If you didn’t have the spare, you could have easily replaced the ’052535′ SIL custom, it’s nothing more than a DAC based on a R2R resistor ladder plus a transistor.I made a replacement some time ago:

Comment on MAME – ‘Color Space’ (Data East palettes) by John Boehm

This is so…cool. Takes me back to my beginning programming days, where we wrote code on 8080 microprocessors and hand-drew circuit designs like this. The end result of your work is (truly) subtle; but at it’s heart, this is what MAME is all about. Great work.
