Here's another find (from http://agatcomp.ru/Pravetz/SuperGames.shtml) -- apple2-based arcade board (fits inside the CRT case) with Mario translation patch

Not in MAME (yet :))

I've took a stab at it but failed. If starting address is 0 (i.e. this dump is mapped at $C000 so that start address is read from $3FFC), then code makes some sense, but treats memory at $00xx as RAM, then accesses unknown slot devices and finally jumps into unknown (no matter what I add to $4000 it doesn't look like useful code):
