[RM2K3] DISHARMONY AUDIO PATCH QUESTION

So, I've been having some trouble getting WAVs to play in RM2k3, but I recently came across this neat little program called the Disharmony Audio patch. (http://rmrk.net/index.php?topic=35306.0)

I would love to use it, but I'm using the official english version of RM2k3, and it appears to be last updated in 2011, so I'm unsure if they're incompatible or if they were, what problems could arise, I guess. If there is an updated version I'd love to hear about it! If nothing works out, I'll ask on the specifications of WAVs in RM2k3.
