Ok found, its unaligned access, which just tolerated on x1000, while x5000 and sam kernels know to be restrict to unaligned accesses of all sort. I.e. bug in code of demo, just by luck/unluck x1000's kernel tolerate it. So those who have crashes, try plz this binary instead of original one, and if all will be ok, will replace archive on os4depot:

I tested it—it's really great in terms of color—averaging 100 fps and never dropping below 60 fps in windowed mode......and yes, the demo is definitely worth playing on the Amiga. Thanks yeahhhhooooooo

Unaligned_fix version, right ?

@All
Found why it fail on SAM460 : missing GART :( Beta version with GART works fine. That can be fixed in 3 ways : in MESA, so to have the same fix i apply for the RadeonHD 3.7 which not have GART, by making SAM460 patch, or by add workarounds to demo.
