Very small but very COOL fix. 

This commit fixed the Hang-up in many games, like "New Super Mario Bros. Wii", "Resident Evil: The Darkside Chronicles", "Fatal Frame 4: Tsukihami no Kamen", "Muramasa: The Demon Blade", and etc. You name it. OH YEAH!

This little issue really cost me some *serious* debugging time, phew...
