Hey guys, thanks for the speedy replies, and apologies for not being a pro Dosboxer, it's just this game is the only one to date I've had any problems with.
When trying to install from downloaded files I'm mounting C: as "C:\DOS". Then I access C: and type "cd gonefish" and try to run setup, but thats when I'm greeted with the error. Same goes for when I use mount D "E:\" -t cdrom and try to run from disc.
the gfish.cfg file contains:
[Path]
CDDRIVE=F
RUNPATH=c:\dosgames\GONEFISH
INSTPATH=d:\GONEFISH\PROGRAM
I'm guessing thats probably nowhere near correct. And if I'm being a 'nooby retard' with all this I do apologise.
