Denjin Makai
Banpresto, 1994

This game runs on early 90's Seibu hardware.
(i.e. Raiden II, Godzilla, Seibu Cup Soccer, Legionairre, Heated Barrel etc).
The PCB looks to have been converted from some other game (a lot of flux traces are
left on the PCB). The game might be a simple ROM swap for some other Seibu-based game.
