Been following Kale's progress with the Sharp X1 driver lately, and came across another emulator than runs on the X68000. Not only that, but this emulator was originally released back in 1993(!), and updated early 1994. I guess back then, no one thought to give it a cool name, so they stuck with “X1 Emulator for X68000”. Also, it's written in 68k ASM, so it's much faster than XM7 is. That is, it does run at a sluggish pace on a 10MHz X68000, but it does appear to run most software. Had to test this in MESS also, and it appears to work very well. Disk images do tend to quickly fill up a 40MB SASI harddisk though. :)

And it's still faster than MAME running NAOMI games on today's PCs. ;)
