@ Lord Nightmare
I can only use 4shared, other uploading sites are censored by gov

@ lidnariq
It is ok with me for sure.

I traced it too, but I haven't tested it yet.

Here's the 3 most useful of the 4 images.

Unfortunately, the gimp XCF really doesn't compress well at all; it's still 13MB so I think I'll hold off uploading it ... unless someone tells me they want it.

The gimp .xcf file with the board tracing would indeed be very useful.

When I say "trace" I meant "labelled", with unique letters at each of the vias.... like this:

If that still sounds useful, I'll put it up on mega, or something. (I'm just being hesitant because my upstream is annoyingly small, so I want to make sure it's useful/interesting)

Labelled picture is useful definitely.
But I think schematic is more useful.
And we already have three MMC2 schematics.

lidnariq: yes, that does sound useful, since it acts itself as a partial schematic.

The midway would be to label nets on the PCB to match a schematic.

Thanks for sharing, Farid! I just can't see to get the file to work.

A mirror would be highly appreciated! That site never works no matter what your browser's settings. All buttons lead to malware attempts. It's gotten even worse since that was originally posted. Does anyone have a mirror, please? :(

Oh wait, those images work well enough. I just didn't try viewing them fullscreen. Sorry, hehe.

Fail, fail, fail again. Keep trying, then maybe this damn thing will work. Eventually you might even know why it worked.

The EPROM's were damaged, so I couldn't dump them.
But as I tested Punch-Out!! (U) [!].nes worked fine on the cartridge.
