This mod is for minecraft 1.4.2 only (maybe 1.4.3+, don't know it doesn't exist yet)

install tracker:
1: in minecraft.jar, delete META-INF folder
2: put contents of putInMinecraft.jar folder into minecraft.jar.  Do not put the folder into the jar, just its contents

for sound to work:
1: install Risagumi's AudioMod 1.4.2 (once it exists) - http://www.minecraftforum.net/topic/75440-v132-risugamis-mods-preliminary-updates/
2: put contents of putIn.minecraftFolder folder into %appdata%.minecraft.  You should end up with a .minecraft\resources\mod\sound\tracker folder
