So I've come back to WoX for another playthrough after a few years and a few hard drive wipes. Installed WoX via Galaxy and immediately noticed that, with the new client, there's no explicit option to install the Full CD version, but the installed version has all of the speech output as .OGG and the ISO TOCs seem to point to them properly via relative paths. I go through the process of configuring my frontend like always, attach my desired soundfont, run INSTALL to match config, enable speech in-game and... nothing. No voice, no head animation.

So I uninstall completely, reinstall, and try with the default config... nothing. No voice, no head animation.

Swap to the floppy version for a quick test. No voice, as expected, but heads animate.

Anybody know what's going on here and/or how this might be fixed?

Scratch this, and have this as a warning answer. Turns out it was my save that I sav2wox'd. It just would not play voice. A fresh save, created in the Full CD version, worked perfectly.
