Gryzor (Contra) - Japanese version bootleg '712-47'  
====================================================
This ROM set is taken from a Gryzor (Contra) bootleg board, with Japanese ROM
and an engraved model number '712-47'. This is a single large two-layer PCB
with NO custom components on it (there doesn't even seem to be a PAL, it's
all discrete logic). The game runs on two MC68B09EP processors; audio output
is provided by one YM2151 and one YM3012 chip.

This is a bootleg on a totally different style board
than a real Contra.
No custom chips, but lots of PALs.

CPU: 6809 (x2)
