I believe Disk 1 serves the same purpose in each and every release aka "boot disk", while the loading screen remains peculiar to each scenario disk. Disk 1 might be slightly different (in structure) among the different releases, but it can be used to load both scenarii disks in the same way (either cracked or original).

If your original of Garrison II doesn't show its own loading screen (the four characters fully equipped standing up against a brown stone wall), then maybe it has been tampered with too!
