Re: [hatari-devel] Hatari Falcon emulation segfault with EmuTOS

[Laurent Sallafranque <laurent.sallafranque@xxxxxxx>]

Hi,

I haven't got this problem actaully with tos 4.02 fr and 68030 cycle exact.

This demo is one of the timing sensitive ones.

I've done many tests with it where I had the illegal DMA sound problem, 
but with the current timings, I haven't got it.
(But the demo freezes while displaying the gouraud fruits).

I think it'll become better in time when I have some time to continue to 
add the correct falcon timings.

Regards

Laurent
