魔獣の王国 (Majuu no Ohkoku)
Recorded with MAME32FX and FRAPS

1987, Arcade, Konami
Not to be confused with Devil World, the Pac Man clone for Famicom.
Borrows the Gradius power-up system
(Correct me if I’m wrong) The first arcade game ever to utilize the Buy-In continue feature as used regularly in beat em ups etc.

The other variation of this game (Dark Adventure)is different from this. The Gradius power-up system was scrapped in favor of a third character which makes it three players instead of two.

It may be two players but I did the button multitask method so it was just me the whole time.

MAG.MOE - The MAG, The MOE.
