Hey i just really quickly made this account to solve a problem on my wii(ive had it for 2 years with no problem). I mainly play wii sports and i played it today. This morning my swings in baseball and tenis were fine. After i updated my wii( i usually never check) i started to play some baseball and my swing and my button press were slightly delayed.( it might seem small but it makes a huge dif) It messed around with the sensitivity and the sensor bar nothing helped. I even tried playing in the dark.
