Nintendo has successfully brought down two websites that were hosting old Nintendo Roms for Nes ans SNes games. It seems this may be in part to Nintendo wanting to clear competition for a planned release of official retro roms for their current console. I can see it from their point ( I used to work for them in the 90's) but as the games mostly in question are in some cases approaching 30 years old, you have to ask why. They already made millions back in the day, the retro rom market cant be that lucrative surely. I know 80's and 90's retro is cool but a lot of the retro rom market is a nostagia thing for us old farts who were there when it was current, and want to remember our spotty teenage years.
