Re: [hatari-devel] EKO System crash

[Laurent Sallafranque <laurent.sallafranque@xxxxxxx>]

Hi Thomas,


AFM is still working as before (I mean perfectly except when I select 
the equalizer which produce a glitchy sound. This was here before your 
patch and I suspect a DSP problem I'll try to solve one of these days.


Thanks for the "EKO demo patch". That should be also useful for F1 racing.

But with the latest versions of hatari, I had the tridi part music.

In fact, sometimes I have the full music in the demo, sometimes the 
music "crash" in the first part and comes again at the beginning of the 
tridi part (the demo resynch the crossbar for the 2nd part of the demo.

Maybe related to accuracy speed of the falcon emulation and crossbar DMA 
addresses feeding.

Regards.

Laurent
