14 texture packs


When you extract the Project64 emulator, put these in Plugin\GFX\GLideN64\hires_texture folder. 
Next open the emulator. Select Options, Configure Graphics Plugin...,  Texture enhancement, and check "Use texture pack"
Then load the regular ROM with the emulator

Some of these aree pretty nice while others are kind of... meh. These are all of the ones I could find, aside from a few more Mario ones, which I didn't include. But if you know of more then please let me know
