Official patch? Naw, SEGA has nothing to do with this. I'll probably put up my modified afs file (it's ~370MB), which is a very simple backup/replace.
edit: I do realize that due to the commercial work I've done for Square Enix, Bandai Namco, etc. I'm in a very oddball quasi-official state for this though. On one hand, it's probably not going to go anywhere contacting SEGA about it, or inquiring if Sakimoto-san wants to contact SEGA about it. On the other, VGO works with Basiscape a lot and I fully intend to make use of any extra time in any hypothetical orchestral sessions we're doing for him over the next few months to record stuff for this (
if we're ever ahead of schedule in a session, obviously)
The way I'm seeing it go down is basically 1) It's a bunch of covers of music from a video game, similar to what people (including myself) do all the time. 2) Just so happens that a mod tool exists to swap music in the game, so why not make use of it. In the spirit of PC gaming and modding and hi def, etc.
edit2: Speaking of VGO and Hitoshi Sakimoto,
FFTactics & XII medley has been a concert repertoire staple for a few years. What I would give for a budget to record the entirety of Valkyria Chronicles with the ensemble.
