INSTALLATION INFO:

The textures for these characters go in a folder in the Project64 directory (Textures/WWF No Mercy/GlideHQ). They are loaded by enabling the 'show texture enhancement options' option in the graphic settings. Then go to the 'texture enhancements' tab, change the format to 'Rice format', and enable the 'texture dumping/editing mode'. When booting the game up, hit 'R' to load these textures.

Further instructions are included in the downloaded files.
