Re: [hatari-devel] Data cache Issues?

[Laurent Sallafranque <laurent.sallafranque@xxxxxxx>]

I don't know if this is related to recent changes, but the demo yepyha 
by Toons runs much longer than before.
It shows some glitches here and there and the music seems to glitch 
also, but I can see many effects.
Now, it crashed on a double bus error ==> cpu halted with a new gui I 
never saw before ,)
