Animal Crossing

Animal Crossing is a video game series developed by Nintendo, in which the player lives his/her own virtual life in a village populated with anthropomorphic animals. The game takes place in real time, reflecting the current time of day and season. The individual games have been widely praised for their uniqueness and innovative nature, which has led to the series becoming one of Nintendo's leading franchises. As of January 2010, over 15,000,000 units of games from the Animal Crossing series have been sold.

NES Games: Bad Graphics
NES games are distorted by default. They require RealXFB to display correctly due to scaling. You can also avoid that by using Progressive Scan to play them without RealXFB. Also playing them on the GBA works without RealXFB, obviously.

Real XFB: Blinds Effect
If the External Frame Buffer is set to Real, after the Nintendo logo at the start of the game, there can sometimes be an odd effect where it seems like you are looking through some window blinds, only in technicolor fashion. This only happens if the External Frame Buffer under Graphics > Hacks is set to Real, so to fix it just disable it. This is fixed in the latest builds.
