Hi

these games are now fixed.
There was a bug in the way the DSP handle interrupts and the HREQ 
signal. It was not visible before with old cpu core, because it used a 
"simplified" mode of how DSP's interrupt should be handled by the 68030.

But with the WinUAE cpu core, I rewrote MFP and DSP level 6 interrupt 
handling, and this exposed this bug in the DSP code (see other thread 
for more details)

Jewelz stays on the "paradize" image at start, but maybe I need to press 
some keys ?

Maybe this also fixed some program that used DSP's interrupt (mod/mp3 
player)
