 ;OniBrowser being able to load PS2 M3GMs (a mystery of the modern times)
-:Somehow OniBrowser is able to display M3GMs from PS2 instance files (except those with textures), even though all the links (PTNA, TXCA, IDXA) are in the wrong positions. Apparently, in the case of M3GM, OniBrowser reads in all the fields past 0x0C as a bunch of non-typed instance links, then identifies their types and populates the PNTA, VCRA, TXCA and IDXA references with the first encountered instance of the matching type.
