Does any one know what the 3ds most used model format is if so what is it?
.BCMDL = Mario Kart 7, Super Mario 3D Land, New Super Mario Bros. 2...and maybe used on other Nintendo's 3DS games...
3ds uses what RachetMario said, but also uses BCH model format too, which is a pretty big mess of strings and what-not... BCMDL is actually more easier to rip from than BCH.
What program can use to open BCMDL?
EFE - Every File Explorer and Ohana Rebirth.
