I confirm that the reverb sound FX in some games are playing correctly now (e.g. tunnels in R4).
But on the other hand, it seems there's also a regression, because now, the L/R audio channels are inverted (as the Wii itself has an inverted stereo channel lol). It didn't happen in previous releases, I think (I play with headphones, so it's easy to notice when a sound FX comes from the wrong side ^^).
Note: this inverted L/R audio channel is fixed is most apps (USB Loader GX, Nintendont, SNES 9X, etc).
