Megadrive 1 & 32X mods
on a model 1, there's no easy way to add s-video as far as I know. you'd basically have to build a RGB to s-video encoder. for the 32x, I'm not sure. if you want s-video through the 32x, you don't need to mod the genesis.
there's no known way to switch the 32x to 60 hz, I'm not sure it's possible at all.
