Editing Masks in Majora's Mask

[georgecarlinllc]

I'm a novice modder getting the hang of using UoT. I'm in need of some help as to opening and editing the actual mask item models that Link wears on his face in Majora's Mask. Specifically the deku mask. How would I go about doing this?

Thanks in advance.

First, you'll need to decompress the rom with zdec if you haven't already.

I'm pretty sure the masks are in the gameplay keep, which is at 0x0108B000 in the rom. You can extract it with GZRT
If it's not there, you'll have to take the long road:

• Download Rice's N64 graphics plugin and place it in your emulator's plugin directory
  
• When the game first start, go to your graphics options; Texture Filters -> dump textures to files. Put on the mask in game so it'll dump the texture to pluginfolder/texture_dump/ZELDA MAJORA'S MASK (or pluginfolder/GFX/texture_dump/ZELDA MAJORA'S MASK).
  
• The texture will most likely be either be CI8 or RGBA16. if it's CI8, you'll want to find the texture in the ci_bmp folder, open it in a hex editor, copy everything after 0x436, and search for that in the rom. Otherwise, you'll want to open the texture in the png_all folder in GIMP, export it as a .tga file (no RLE compression), convert it to raw RGBA16 data with my tga2rgba16 converter, and search for that in the rom
  
• Now, find the file in the filesystem that contains the offset of that texture, and that'll be where the masks are

Once you've found the file with the masks in it, you'll want to change the extension of the file to .zobj, open it in Utility of Time as an individual file, and find the mask you're wanting to replace. Once you know the offset of the mask, you can pretty much follow the same steps posted in this tutorial to replace the mask with your own model.

It's a bit time consuming, but have fun
