I’m not certain what else I can try.
I have an A4000D here with A3640 doughterboard but it has a 68060 mounted.
It’s running Amiga OS 3.9BB2.
When I start a WHDLoad game it starts, but after a few seconds it freezes where I can only make a reset.
With Elite for example, I can see the Elite spashscreen, showing the Cobra MK3, etc. but it just hangs there. All games I tried are like that.
I have tried a number of WHDLoad options, like MMU, NOMMU (which doesn’t really work on 68060), NOVBRMOVE, NOCACHE, NOAUTOVEC, etc.
But nothing helps.
What could this be?
