Zatch Bell DFF and MDL issues

[psychonautic]

Well, maybe you should try a different method. Since the game is for GameCube, you could rip the models with Ninja Ripper and import into 3DS Max. If your lucky the models will come out in T-pose.

Alternatively, you may be able to open the PS2 .DFF files with RenderWare if you where to somehow obtain a copy of the game.

I was really hoping this would work but... It doesn't. the 32bit version of dolphin rips textures only and the 64bit version just freezes without any ripping. I tried seeing if the ps2 version would work in the renderware viewers but the only difference is that it takes longer to read them and not work >:1
