@Rusty BreadbinI've had some (limited) success adding the Amiberry keyword
_AGA_ into the filename of the whdload files before reloading on the A600GS. I was able to get Moon Patrol going this way and it also solved a freeze I had during loading for Ruff 'n Tumble (though this was a known whdload file). Unfortunately, this doesn't work for everything.
