Unreleased & Unknown Nameless Neo Geo Fighting Game Prototype Found

Unknown-Neo-Geo-Prototype-Fighting-Game-FoundWhen it comes to prototypes and cancelled releases, we’re often familiar with what’s waiting to be discovered thanks to the various reveals and previews shown in magazines beforehand. So once an unknown, unidentified and nameless Neo Geo fighting game turned up at auction, it’s safe to say the retro gaming community was left in awe.

Sharing a selection of screenshots and video footage of this incredible find, Neo-Geo forums member NeoTurfMasta couldn’t believe what he stumbled upon. Costing ¥‎69,887 on Yahoo Auctions Japan (approximately £457), the prototype/development board unfortunately arrived in a non-working state upon arrival. Unlike traditional prototype cartridges with rewritable chips soldered on to the board, this one used its very own flash memory cards which could be slotted in and out during development. After a bit of tinkering around and archival work, what was left of the unknown release finally booted up.

With no title screen present in the game and what appears to be no identifying information left at all, it’s yet to be known who made the game or what it was called. To help with the hunt NeoTurfMasta has generously sent the ROMs over to the MAME development team. The hope here is that the gurus behind the arcade emulator will be able to get the dumped data working and out there for all to experience.

In the meantime, NeoTurfMasta also decided to present the game to the public at the Midwest Gaming Classic event which took place this weekend. Despite plenty of retro gamers battling it out on the prototype, we’re still none the wiser as to what this game actually is.

Some more info's shown up thanks to some digging from Twitter user gosokkyu- it is possible the game was from FACE (who worked on Voltage Fighter Gowcaiser with Technos), and the working title was possibly Dragon's Heaven.

This is a hell of a find though. An otherwise-undocumented, unreleased game! Extraordinary!
