Yes, supposedly Hyperion's license agreement is restricted to operating systems named "AmigaOS", which would allow for ports to OS3 (m68k and PPC/WarpUP) and OS4, but not to MorphOS.

I doubt the licensor will get any revenue from it, or got any from Hyperion's previous Linux, Mac and OS4 ports of the game. Hyperion has usually negotiated lump sum game licenses in the past.
