[hatari-devel] Twelve demo bombs with fast-forward and freezes on Falcon?

[Laurent Sallafranque]

I've tested with IoMem_WriteByte : voice.prg works no (with a little 
other problem).

The game conquest of elysium works too (no more freeze).
Should I commit this ?

May this corrects the problem you encounter in monochrome mode with 
twelve demo ?

Regards

Laurent
