I've just put up an article on the excellent (but short!) prototype of The Firemen for the SNES. Though it is an NTSC prototype, and the script is in English, I don't actually think this is an unreleased US version. I suspect it is actually an early sample of the PAL version of the game, but they hadn't finished converting it to that format. The script is compressed, so I didn't do a full analysis comparing the prototype to the PAL version, but there are plenty of discrepancies. Obviously, the script had yet to be proofread by a native English speaker. Click here for the article.
Nice article! I know Human best from Fire Pro Wrestling games, however, they made a lot of interesting games, mostly in the SNES era, but also a handful in the PS era too. Did you get any prototypes of Fire Pro in your lot of Human protos?
Indeed I did. I have prototypes of Super Fire Pro Wresting 2 and 3. Articles on those prototypes are already on the site.
