Latest experimental is sponsored by BitBeamCannon:
Mega Drive target now outputs a ROM that slide-shows through all of the panels in the project (assuming the panel isn't so detailed and rich in color that it can't be adapted to the Mega Drive palette - if it gives you that error, reducing to 16 colors will almost definitely make it work).
While this is far short of being able to actually produce a Mega Drive game with Scorpion (though slideshows are perfectly viable if you want to do that!), it is a major step towards it - in particular, the problems with embedding the "cartridge.se" file into a ROM have been solved.

Emergency check in, issue reported by Mixel with the engine not working at all.
I'm still working out a few kinks with compiling the Amiga and Mega Drive versions of Scorpion, what I think happened is I might have accidentally compiled the Amiga version with the Mega Drive source, whoops.
