Any way to mod the 2K22 archives directly?

[vetmin]

...i.e., not using looyh's Hook, but directly opening and modifying the contents of the extensionless archives in the main NBA 2K22 game folder? My understanding is that one could previously use 2K File Explorer for this, but that it no longer works for newer 2Ks. I did try renaming 3M, for instance, to 3M.iff, and it opens, but it's not showing the full contents one sees in the manifest. (What I'd like to do is use custom *.wav files, since they're un-Hookable, afaik.)

Thanks.
