Hey, I've just purchased Motion plus and played Grand Slam tennis and Tiger golf 2010. First, Tiger works great!!! especially the disk throwing game... that game actually feels like almost true 1:1 motion!!! But.... Grand slam in the other hand...... that game feels really... inaccurate and awkward... unlike the promo trailer that was shown by some dude how motion plus works on that game, the character does not really follow what I do.... especially the forehand...... it's weird... but backhand works okay.... but not perfect.... I'm sure that my motion plus has no problem since the TW golf disk game worked perfectly for both side 360 degree!! I'm running on HDD loader / LU64 / 3.4U Do I need to update or download some patch or something?
