"Most people say that 90% of Game Boy Advance games all use the M4A sound engine (which is the only one we really know about), and there are only a few exceptions.
That is a lie! Here is an extensive list of games, NONE of which use the M4A sound engine. In fact, they all use the same sound engine."
You posted a list of 133 games. There are 1538 officially licensed games on the platform. I'd say the 90% claim is pretty accurate.
