So how exactly do you play these blur free Nintendo 64 games? Well if you own either a Gameshark/Action Replay or a flash cartridge such as the Everdrive 64 or the Retroactive 64drive, you're in luck. Codes have been made available for a wide range of Nintendo 64 games for the cheat cartridges, whilst those with flash cartridges can apply patches to their game ROMs for ease of access. Furthermore the strength of the codes can be adjusted should you feel a little less anti-aliasing removal would work better.
It's worth noting though that the codes and ROM patches are region specific, so make sure your game matches up to the hack provided.
