I don't know if it's progressing any more or what state it ended up in, but some modder was attempting to fix issues with it in recent years. I believe he successfully restored the soundtrack, which you only can hear in the game selection menu in MAT3 (Digital Eclipse when preparing the main menu apparently wasn't aware what was happening over in China to its original soundtrack), in a couple of versions of it for example.

I think he was attempting other fixes as well.
