It is a cartridge image file. In Vice, you can connect it using ALT+C shortcut. Or you can put it on a SD Card if you have an EasyFlash / Kung Fu Flash 1 or 2.
I know what it is, I was wondering why the table says to load the disk version on certain platforms, but there's no disk
The table is about save/load game feature and indicates the Save Target
Oops! My bad. By the way, disk saving is working on a real C64 if you use at the same time a sd2iec and a KFF 1/2.
