Alright guys, I've been playing Minecraft for a while now, and I need something to spice up my Minecraft home screen! ! I've been trying for days now to change the mclogo.png in the minecraft.jar (by using ). I open it up in Photoshop, but then it doesn't enable me to edit anything! I can only delete the Area where the Original mclogo is! Is somebody able to help me with this? Thanks, in advance.
