This fixes a conversion error that causes mic update events to be run far more frequently than intended, causing massive slowdowns in some games. After fixing, I experienced a 5x speedup in The Sims 3.

Prior to this PR, the speedup could be achieved by using a savestate. This was due to a bug that unscheduled the mic update event when loading, which this PR fixes.

It used to be The Sims 3/Pets is slower with New 3DS mode enabled. With Save State PR combined it cause even more slow down. This is no longer the case as it is totally fixed with this PR. New or Old 3DS mode makes no performance difference now.
Just leave a note here for future reference.
