Didn't need Rolfe to tell me about this game, have known about it for years, the game is pretty batty (pun intended). Go play it in MAME now, it's that good, considering it took years for it to be emulated as well as it is now. Still far from working permanently, and one of a few Irem games that doesn't have a second loop to it.
Great Irem arcade game, but what's left of Irem I hear come September will shut their doors down forever. Sad to see a once proud arcade giant go out like this, but they just didn't have the funds to remain open, plus they haven't put out anything much of note anymore.
Praise R-Type, praise Ninja Spirit, praise Ninja Baseball Bat Man, praise Dragon Breed, praise Kickle Cubicle, praise whatever other IP's I know of but won't list as this could be a long sentence.
