This worked perfectly for me, bravo man.
That's exactly what I was thinking, something along those lines.
/* NOTE!!! I did not rename my minecraft.jar file to minecraft_1.2.5.jar but minecraft_1.2.5 because the .jar extension was already associated with it and it would in turn rename it to "minecraft_1.2.5.jar.jar" Just a friendly note for those who might not know.
Thanks again man.
