this be a great product - except for the fact that it can and will crash you game . it have great code and they be all great and really help you win the game . half the game would be really hard to beat without it . but , it crash my Animal Crossing Wild World game once and New Super Mario Bros too many time to count as well as Mario Kart . it work well , but do not get too dependent on it , as it may and probably will crash when you need it the most -lrb- about to defeat the game , main boss , etc etc. . . -rrb- so be warn it be good , and actually work really well until u get too dependent on it when it fail u.
