I'm wondering if it's possible to make a single multi-cart that will work in an MVS as well as AES consoles. If there is some physical differences, can a switch be added that allows one to switch "mode"?A unibios allows that.
I know many people (including myself) have both AES and MVS (one for TV, one for my Sega New Astro City). It would be nice to have 1 cart that moves between both systems.
