Mad Motor (c) 1989 Mitchell Corporation
But it's really a Data East game.. Bad Dudes era graphics hardware with
Dark Seal era sound hardware. Maybe a license for a specific territory?
"This game is developed by Mitchell, but they entrusted PCB design and some
routines to Data East."
Emulation by Bryan McPhail, mish@tendril.co.uk
