Bugs:

- Clone a51mxr3k: Go into test mode to adjust the volume, reports the sound CPU is not responding, and the geme gets stuck. Reznor007 (ID 00396)

- Clone a51mxr3k: When doing the disk check, the throughput seems locked at 3999KB/sec...which is slow compared to the real thing. Reznor007 / Luigi30 (ID 00397)
