Running the patch file seems to require the Zoo Tycoon Update 10.12 disc 1, as if it's trying to locate a specific file (specifically FILESUSA.CAB)

Really? It's running fine with my install of complete collection fresh out of the box.
Found something - The patch linked from PCGamingWiki doesn't apply to the complete collection. The linked version is also for 10.9, rather than the 10.12 I picked up.
10.12 still seems to exist, but no complete source of it.
