I have a friend who swore he memorized the code to get everything and be at sigma. So I pulled out my old snes and put in mega man x, and lo' and behold he did remember it after some 10 odd years.
I miss the way there used to be cartridge's, the sprites, and the way stories considered generic now were pretty awesome back then (looking at you Zelda: Link to the Past). The 90s were such simpler times.
Plus remember Maxium Carnage?
