Can you say "DLC_Tool" ???
Work in progress. The "ASH0" recompression may take a little more time. Hopefully coming soon.
Here's the output: http://aibohack.com/wii/dlc_1.zip
Contains textures and palettes in BMP format ready for editing similar to NPC_Tool
Also the 3d model (a "MDL0" file saved without header). Eventually someone will need to write a simple 3D tool. In the mean time hopefully people will be happy with different color pikmin hats and funny shaped leaves...
