Crossdos (prior to v7) truncates characters to 8.3, so your cf.slave
might well now be called cf.sla
- check for the file inside that directory and rename if appropriate.
Hopefully you'll get away with the rest, because I've checked the zip and everything inside the cf_data directory adheres to the 8.3 limit.
You might want to rename the game icon back to CannonFodder
to be sure.
In future, I'd recommend you LHA or ZIP stuff prior to sending over crossdos. Then when you extract on the Amiga side, all filenames will be preserved. Plus you'll squeeze that little bit extra on those horrible little disks!
You can get an unzip utility from Aminet, it's probably easier to use this format as Winzip is a nice quick util to zip stuff up.
Hope that helps
