Was up around 3:00 am to try and recover some data in the two partial base64 encoded .zip files.
Whelp.
So far, the best I got was full GMB-NEW.ASC, a text file from New WinZip File.zip
NO$GMB.EXE not so well.
Most interested in desert.zip. desert_final.pcx from what I can see so far is 1024 x 1024 8bpp.
This one was far more successful.
