In the DOSBox Portable page, it says you can set up C in the DOSBox to point to a path on your portable drive by adding this to the dosbox.conf file:
mount C: \PathOnMyDevice
I created a folder named DOSGames on the root of my thumb drive. However, "mount C: \DOSGames" doesn't work. I've only been able to get it to work if I do "mount C: G:\DOSGames". I'd rather not do this, however, since the thumb drive doesn't mount to drive G: on every system (it's G: on my work PC, but I: on my home PC).
Any advice on how I can make this generic?
