/*

IREM M97 board

CPU is V30? V60?(Irem/Nanao custom), Z80+YM2151 for sound

The main CPU is encrypted.
It uses a simple opcode lookup encryption, the painful part is that it's
preprogrammed into the IREM D800 cpu and isn't a algorithmic based one.

So unless someone wants to go though all the permutations I don't see it
being hacked very soon
