Ok, this is definitely wrong.
I very strongly suspect that this is part of smsq_atari_hwinit_asm,
which should however go :
at_mdloop
move.w (a0)+,(a1)+ (NOT moveq #$41,d5)
cmpa.l a2,a1
blt.s at_mdlopp
rts
You can check this, hopefully, by checking whether a few bytes before
these instructions you find the string "Use sprite for cursor".
If this is really there, then somehow the instructions get corrupted,
making the move.w (a0)+,(a1)+ into a moveq.
Could you disassemble the code as of the address contained in A6, which
is a few bytes before the loop?
Is there really no way you can insert a breakpoint into the code which
would call up your debugger?
