[color=green:e505ac35ed]What's these ? 

Mighty Mighty Missile looks like ChuchuRocket, and a demo is available [url=Mighty Mighty Missile]here[/url], after a quick research, it seems to be an homebrew

And most of these games are already available on sega genesis/megadrive...

I don't know about these selling, they're strange...[/color:e505ac35ed]
