Mmm, probably, but my interest is on mainstream 2D consoles with a good C devkit. For example, I don't think people would be interested in a port for PSX or Dreamcast, those are 3D machines. On the other end, Sega Saturn has a great reputation for 2D stuff.
I also have another rule, being able to test on real hardware on my side, which means getting the console and a flash card, in the long run, it costs a lot.
