Before someone asks for a third version of the trainer,
the current Retail trainer (not the Steam one) works with the GamersGate version of the game.
You simply have to use a no-cd fix.
I don't think I am allowed to post that kind of link but :
- as always, keep a backup of your original "condemned heroes.exe"
- and, as always, scan with your antivirus the file(s) you download.
Have fun !
