Minna no Rhythm Tengoku - Crash after multiplayer game

[~Poke~]

After completing a two-player minigame (the fork one) it gives this error:
Backpatch : Currently only supporting reads.
Attempted to write to 313034e0.

It then proceeds to crash.
I've tested this twice, it happened both times.
Any suggestions? Or is this a bug in the emulator itself?

My specs:
Windows 7 64-bit
Intel Core 2 Quad CPU Q6700 @ 2.66 GHz
8 GB of RAM
ATI Radeon HD 5700 Series Graphics card
