Curious about an old MS-DOS game (Another World) I tried viewing it using the MS-DOS editor (which came with Windows 95 and up) , but unfortunately it turns out to be compressed. There's a "DIET" label in the header and no other legible text. Unp.exe can't decompress it and the Diet utiliy I found appears to be unable to decompress self-extracting executables. Apparently there's a utility called CUP386 which allegedly can decompress self-extracting executables, but I can't figure out how to use it. Does anyone know of utiltites which can decompress Diet-compressed executables?

Supposedly diet -RA ... does the trick but I just get an error about there being no files or something to that effect.
