    Sound:  OKIM6295
Set 3
    CPU:    MC68000, Z80 (for sound)
    Sound:  2x OKI6295 (Sound code supports an additional YM2203, but it's not fitted)

Power Instinct
Atlus, 1993

This is a bootleg US version with different sound hardware to the existing bootleg set.
The PCB is very large and has 2 plug-in daughterboards and many MASK ROMs.
The addition of the contents of the MASK ROMs would probably equal the contents of presumably
larger MASK ROMs found on the original PCB....
