Hi Dr Bong
The OldGamesFinder doesn't actually have any ADF files. The one it links to on Lemon doesn't exist. It's basically a link to a page that links to other places that don't have it.
I checked there.
The other leads to grandis.nu, which requires an FTP username and password.
I'm making my ADF freely accessible to any who wish to actually download and play the game. I will definitely put your other two titles on my radar, though. Delta Patrol looks like Choplifter in the screenshot. Monkey Business - a Donkey Kong clone? I'll keep some feelers out.
Are you sure Delta Patrol was even released for Amiga? Wikipedia lists it as only for the C64 and ZX Spectrum.
