I wish it was that easy.
Unforutnately to run it off a DVD there is no variable I can use (a variable such as %currentdrive% would be excellent but unfortunately doesn't exist).
Basically Gamebase uses absolute paths:
I want it to use:
.\gamebase\games (as the emulator is run from there it uses gamebase as it's home dir)
However gamebase doesn't like this.
I'm sure theres a way around it though and as soon as I find it the DVD is complete.
