weird stuff going on with my wii mote

i recently bougth a copy (pirated copy) of silent hill sharttered memories, the wierd is that my wii mote loses its synchro ridicolous fast and frecuently, weird stuff it does not happens when its about just using the wii mote to navigate, and i had problems with the wii when i tried to isntall Wad magnager and the previous MCIOS patch of wanioko.my questions, is my wii near a brick, semi bircked, etc?, or is it a problem of my wii motei dont know the chip model but i can say its one of the first gen wii's seial number being: LU51174366 and within a square a 3its runnng homebrew channel, it hasnt been parched or anything, its on the horizontal positiondunno what else i can include but its running system menu 4.2U

the only thing i can think of is that the game tries to use an ios that you dont have an it cuts the remote out, thats all i can think of thoim stumped
