What EMU are you using Fred and what version is it?
Where did you get the disk images for the games?
I have Winx68K, ex68 and xm6 lying around but I'm not sure which to use or what the latest versions are.
Currently I have 32 games but some don't seem to work.
I agree with you that the X68000 has some great games, although Super Aleste still gets my vote as best shooter.
