prodigy and Gatsby: I believe he's referring to the original Diablo and not Diablo 2, in which case, there would be a file named single_0.sv I wish I could help, but I do not know how the save files work in Diablo. The only thing I could suggest is copy that file and see if you can install Diablo on another machine, paste the file into the correct folder and see if it works. I don't see why it wouldn't work, but ya never know.
