hi

regarding hex pistols when running in 68060+fpu internal, there's a 
short black screen, then it loops on this :

cpu video_cyc=  8590 398@  8 : 001D4132 082d 0000 fffc           BTST.B 
#$0000,(A5,-$0004) == $ffffa202
cpu video_cyc=  8591 399@  8 : 001D4138 67f8                     BEQ.B 
#$f8 == $00000000 (T)

-> it waits for "ISR Receive Data Register Full", which seems to never 
happen.

At the same time, the DSP is mostly looping on this :

Dsp set TX register: 0x000000
p:0010  08dfef         (04 cyc)  movep y:(r7)+,x:$ffef
        Reg: r7  $19d7 -> $19d8
        Mem: x:0xffef  0x000000 -> 0x000000
p:0011  000000         (02 cyc)  nop
p:013b  0aa980 00013b  (06 cyc)  jclr #0,x:$ffe9,p:$013b

Someone used to DSP might see where is the problem ?  (it loops the same 
with hatari 2.3.0, so it's not a recent issue)
