UPDATE (11/17/2006):
Jim Karpen’s related article may also be of interest.
Many users have reported (see for example
this,
this,
this and
this) it wouldn’t switch to next tracks in
Tournament mode and/or wouldn’t add money to the account.
Some people (see for example
this) say you must install it to the main memory to fix this problem.
I’ve thoroughly tested the tournament mode on my x51v in three cases (game copied to the root of the built-in storage of the device, the root of the SD card and a subdirectory on the card); all three worked OK with me.
However, if you
do encounter problems like the above,
try copying the game to the main storage of your PPC to see whether it helps.
