Thanks, but if it were an ordinary .zip file, I would have known what to do with it. It's an .RAR file, probably specific to Runaway. But there are no other .RAR files to be found in Runaway and there are several game folders, so I don't know which one to put it in. I suppose I could try them all and see what happens, but that might involve opening the game several times with disk 1, swapping to disk 2 to open the saved game in ch. 3, then crashing to the desktop heaven only knows how many times...Not my idea of fun.
I was hoping someone had tried this already or knew of a link explaining this really unusual patch.
