The "uncompressed audio replacements" will be pretty nice, it will be interesting to see what comes of those.

There is a guy, Mathew Valente (a.k.a. TSSF), who put in a surprising amount of effort tracking down the original samples used by the composer of the SNES and PSX Final Fantasy games, Nobuo Uematsu. Nearly all of the samples came from various contemporary hardware and software synthesizers. Mathew found most of them (possibly with community collaboration, no small feat either way!) and took those original samples and remastered Nobuo's tracks. If you watch his videos, this was not a simple drag-and-drop operation, there is quite a lot of technical, musical, and subjective work and decisions to be made. The results are just beautiful.

If you liked classic Final Fantasy music, you'll love his channel. Here's one of my favorites: https://www.youtube.com/watch?v=XQhxNkZH-DE
