yes, fpu doesn't matter here.

Hi,

thanks for tyour tests.

I already saw this kind of behaviour but can't really reproduce it, 
maybe it's related to the "auto insert disk B" ? Or do you use a zip 
archive where the 3 disks are located ?

flickering is normal. I don't see that many glitches, except the usual 
ones due to spectrum 512 images.

Can you try to compare with Hatari compiled using old uae core ? (save 
screenshot for both cpu and compare them)

Can you tried the versions here http://www.pouet.net/prod.php?which=498 
? DF_STERR.MSA works for me. Does it crash with old cpu too ?

works for me

works too

prints a lot of address error message while loading, but that's part of 
the decoding routine I think. then the demo works


I think the problem in your case could be that 24 bit addressing is OFF, 
but for 68000 it should always be ON.

Can you try again when it's set to ON ?
