This mod is for minecraft 1.4.4/5 (and maybe 1.4.6 and above, but I can't test those before they exist!  If you get this after 1.4.6 or above is already out, it probably works and I didn't bother updating it just to change the readme)

install map:
1: in minecraft.jar, delete META-INF folder
2: put class files and the mamiyaotaru folder into minecraft.jar.
