new NOT WORKING Puzzle 'unknown' XXX [system11]

Browse Source 
need title translated.
there's a PIC used for some kind of protection and maybe sound handling, I've patched out some dead loops it ends up in, but needs more investigation; I don't see any obvious / direct writes for the OKI M6295s either.
PCB is basically non-working.
marked as NOT WORKING because I have no idea how to play it, so can't verify if it works.
