[Zahgurim]

When installing mods in minecraft 1.2.5 do i need to install them into the minecraft 1.2.5.jar or the minecraft.jar?

When i install in the minecraft 1.2.5.jar nothing works.... when i install in the minecraft.jar nothing works..... meta.inf is deleted in both .jar folders.

Also little update tried to install water shader mod didnt work in the 1.2.5 and in the minecraft.jar i got this

did you put the shaders folder in your bin folder?

If you have a look at it, it says it cant find the config.txt

Your minecraft.jar is always the the file you will add mods to if your not using something like magic launcher or it is not a plugin that modloader handles.

yeah i figured out how to get it to work and im using magic launcher now anyway but the shader folder was in the .bin
