Re: Monster Bash - Episodes 2 and 3 in addition to first one free to download

The file_id.diz file is in the first episode but can be applied to the
2nd and 3rd as well. Download that first episode from the site at the
downloads section and put the file_id.diz file in the directory where
you have the other episodes installed. That should resolve the issue.

P.S.: I guess that at the time, all that was required was a file_id.diz
though in some later games, they programmed them to actually put a
strict check on the content of file_id.diz file to check for mismatch
or something.
