(Just click the image to download)It's very simple, just select the version you want to put your minecraft client on, and hit Patch. Just make sure minecraft is closed when you patch it!Alternatively, you can just extract the bin.zip file of any version you want by selecting it in the listbox, then clicking "Extract Bin.zip". You'll then be prompted to choose a save location.Source (be warned, this was thrown together quickly and in a terrible language):http://pastebin.com/dDu5Mq2p ___________________________________________Disclaimer:This program was coded completely by Vaquxine.I (Vaquxine) in no way claim any ownership of any of the files used in this program; this includes but is not limited to: a.)
