anyone heard of HXF file format?

Im trying to figure out stuff about the inner working of the game Pacman World 2 and we can extract the level geometry files and open them in blender. but we cant seem to find out how to view these HXF files for objects and such, heres what the file system looks like if it means anything. but if anyone has ANY information on it or would like to help figure it out it would be extremely helpful

From some quick searching it seems to be a platform specific proprietary format of the studio that developed the game. The game is 20'ish years old so someone may have already reverse engineered it, but there's certainly a chance you'll have to do it yourself.
