It might be possible that the group is a different Supplex but the timespan fits. The text also gives away that the coder zox was German.

text from the binary that is not being displayed by the intro:

hey!!   learning  to  code  in assembler  by lamely  hacking out little loaders
written by other  guys isn't soooooo  easy,but inspite  of this is a little bit
unfair against extremely  hard-coding mates  like me (hehe- hard-coding... what
for a joke!) so, get out of my code,please. (I just could say lamer,now, but if
you aced it to uncrunch this file,you surely can't be worth this title...
     zox (or Ext??) of spx-berlin..  whishes you a nice day and a bright future
     contact me over Deathless... (leave me a note!)

Since there are no hot keys given it is assumed that this was a template for a trainer. However the trainer executes GAME.EXE if present. Unfortunately this file was found without any textfile or additional informations. So any information on this production is appreciated.
