If anyone here cares, a couple of days ago Capcom released a mostly fan-made 8-bit Megaman featuring Street Fighter bosses. You can download it on Capcom Unity. (I owe you guys a link but my phone disagrees.)
It's a neat game. Fun stages, bosses, weapons and most of all: it's free. It does lack a save function, though. Anyways, if you like Megaman, you'll like this.
