Ripping Loaded models from DS Emulators?

[Blonde Sayori]

Howdy, A potentially noob question but I know that there are Programs for a few console emulators out there that can rip Models/Textures that are currently loaded in the Game's emulation during play. Does there happen to be such a program for a DS Emulator such as DeSmuMe? I figure it may be a good way to get around some unknown file and directory types that seem to be either very poorly if at all documented.
