Hey guys, i dunno if someone gets this idea beside me: using the demo SCCT.exe, copy it into the full_game_dir, and use it to run the full game without CD (and without starforce !).
With just the exe by itself it's not working, but I have tryed messing with .dll and /data folder and now the exe accepts to start and reads a lot of files, but crash at the end ... Maybe that some of you can try also..
A low tech solution could also rename files in the demo/data folder and replace them with some of the fullgame levels (not convenient as you can play only 1 level before having to rename/recopy files again)

.
Let me (us) know !
