I can't get MAME32 to create a diff file for the hard disk image games.
I was told to make a folder with the same name as the .chd file and put the .chd in it and put it in my roms folder.
But when I try to run the game it loads about 3/4 the way through and then comes up with "can't create diff file" or somesuch.
Anybody know what I'm doing wrong . . .
