So here’s a nice surprise: three people in Portugal have found a prototype of an unreleased shmup by SEGA for the System-18. Meant to be released in 1991, this game never found it’s way in arcades for unknown reasons. So it’s great that we can finally see what the game is like. While the arcade board the game was found on was damaged, the fanatics managed to get it working by putting the chips on a working System-18 prototype.

Not only that, we can soon play it for ourselves. The group has dumped the game’s code into a ROM and MAME is already capable of playing the game. While the ROM isn’t up yet, we likely won’t have to wait long until it can be downloaded. Another video showing the attract mode can be found after the jump.
