Here is what smsqe does:
move #$3700,sr !!!!!!!!!
move.w sr,d1
cmp.w #$2700,d1 ; 68000?
beq.s copy ; ... yes
move.w #$2700,sr ; ... no, reset to normal
There may be other ways, for example I think C68 has a CPU detection
routine.
However, another problem is that smsqe won't even check for the Aurora card
on 68000 systems, i.e. 68000 + smsqe + aurora is not currently a possible
combination.
Easiest solution to your specific problem (QWord on Q-emuLator) would be to
assume a 68000 CPU when running on Q-emuLator (as I believe you are already
testing for this platform). The worst that could happen is that if in the
future I start emulating a 68020 or 68040 in Q-emuLator, you would still use
four MOVE.B instead of one MOVE.L and on the 10GHz CPU PCs that we'll have
at that time your code will incur a penalty of perhaps a nanosecond ;)
