Reworking game files

GeneWars uses similar engine to Syndicate, Syndicate Wars, Magic Carpet, Dungeon Keeper and other Bullfrog games.

If you want any tools to decode game files, look on "Game Structure" sections on my Syndicate series site:
Syndicate series unofficial fan site

You will find RNC decompressor to decode data files, DAT/TAB reader, RAW graphics reader, sound extractor and many other tools.
