Re: [hatari-devel] EKO System crash

[Laurent Sallafranque <laurent.sallafranque@xxxxxxx>]

I've tested EKO System and it worked perfectly from beginning to end 
with the music all the time.

I'll relauch it a few more time to check if there's no more sound crash 
or if this problem is fixed.

The final music (greetz part) is a bit glitchy but sounds correctly.
