Unlock all Levels
     Create a game profile named "lvl.activate 1" to unlock all levels.

9 instead of 3 retries per checkpoint
     Create  a  profile named "set MAXCNT 9" to have 9 retries on each
checkpoint instead of 3.
     BTW: There's no way to have more or less retries just by altering
the number. This number is hardcoded...

Unlock all ships in the database
     This one is held confidential by the developers...
     Create  a  profile  named "data.setvis 1". While on this profile,
you can open every entry of the ship database.
