I expect to die before I complete this list, but I'm super happy about MIDI power X68000 Ver. 3, since I missed a sealed copy several years ago.
If I had to choose one out of those I'm after, it would have to be KICA-1005. There has got to be a sealed copy somewhere - probably sitting in someone's collection in Japan or USA. Or in a dark drawer in a disc shop in the outskirts of Osaka.

Here's the X68000 album:

I have updated the list, not that I expect anything to happen. The few I found I just had to wait for them to show up on some auction sites...
