Re: [hatari-devel] Falcon tests

[Laurent Sallafranque <laurent.sallafranque@xxxxxxx>]

Many demos suffers sound speed, glitches or unsynchro between sound and 
effects.

It seems that the effects run too fast, or the Falcon DMA sound too 
slow, I don't know.


Until now, I haven't seen other problems.

I continue to test.

Regards

Laurent
