Hi, I've got the VGA version of The Secret of Monkey Island on original floppy on three disks, and during install on the third disk I get:

Ignored Unknown Chunk

and the installer is done. I've ended up with 4 what look like disk files on the C drive, but no monkey.exe.
Oddly, the instructions say that to play the game directly from floppy, run monkey.exe from the floppy, but that doesn't seem to be on any of the three floppies, are these disks just too old at this point?
Thanks,
J
