This topic has me thinking, it isn't totally outside the realm of possibility to make our own pirate port on Genesis of something. BasiEgaXorz is a pretty capable program to make Genesis games, and anyone with some programming experience could figure out how to use it and get something working. Granted it probably can't handle doing a complicated game with lots of physics like Sonic, but for stuff like Zelda, it'd work pretty well enough. in fact, anything that'd have to be toned back would just add more to the pirate quality =p
Just throwing that out there. I'm trying to work on a small project but am having issues finding good graphics, since it's a port of a PSX game and the original graphics just take up too much VRAM to be practical :p
