Hey cool, I didn't know that you were working on this game. Despite many of its issues, I remember having a lot of fun playing this one back in the day. I look forward to playing your hack/spoof when it's done. Hopefully someday, someone will also release a proper re-translation of this game, along with Robotrek, which could also use one as well.
Anyway, I wasn't able to find much info on this game, expect for this one thread on RHDN where someone was working on an improvement mod. I'm not sure if it will be of any help to you or not, but here it is:

Edit: If you look at the third post in that thread by KingMike, he did list some technical info which might be useful.
