This one is special: it only runs from whdload. The original exe isn't protected against direct run but it should, as it's not runnable.

I see, ya one of the secrets of AMINIMIGA is that it uses custom config files (so you can't use the Mini's Configurator features or it will overwrite them). It sets up several HD paths, and also relies pretty heavily on WHDLoad, so I assume it has a custom WHD setup. I also see it gives WB 16MB of Chipmem (0 Fast). So could be the mem, or the custom setup, or a combo thereof :)
