I'll say again what I've said countless other times on other threads when the issue of OCS/AGA compatibility arises.
I have yet to come across a piece of software which cannot be made to run on my A1200 when I'm using the rather excellent
The Ultimate Degrader And Enhancer.
Sure using it will require a little know-how and inconvinience, but getting those ADF's onto floppies using a KS 1.3 A500 will require that much more know-how and inconvinience.
