NFG Games + GameSX

Schematics for consoles are notoriously hard to come by. You may occasionally find a badly scanned copy of a badly photocopied copy of a badly drawn third party SNES schem, or you might know a guy who knows a guy… But that's more or less it.

I had to take matters into my own hands when it came to the PCEngine, and the results of this crazy note-taking and painstaking trial and error are below for your enjoyment.

And maybe other consoles as well. Add 'em if you got 'em.

Remember that the PCE and CoreGrafx (and, in fact, all PCE hardware) use the same three chips. Even the SuperGrafx uses them, albeit with an extra new trick or two thrown in…
