Has anyone tried GenesisPlus 1.4 on MorphOS 2.1

This great Sega Genesis / MegaDrive Emulator worked fine on my old 1.4.5 setup but now it don't.

There is an error message by the log server saying that there is an illegal instruction by the program GenesisPlus.

Any ideas?

Have you installed the lowlevel.library from the "Contributions"-Drawer on the MorphOS 2.1-ISO? IIRC it's needed for GenesisPlus to work.
