Why not just buy a license to use an already existing Genesis emulator (for the Dreamcast) and sell it that way? It can't be that expensive. And most of the emulation work would already be done.
The rest, yeah, that needs some more funding.
And sorry for complaining, but you should really get whoever's doing the redrawn art to... redraw it. It looks like a high definition touch-up job - kinda off. That picture of the girl looks weird as heck.
