      Description

      The Minecraft Launcher claims to have the version "a1.2.1" available, but it is a copy of "a1.2.1_01". Upon inspection of the .json files, both "a1.2.1.jar" and "a1.2.1_01.jar" contain identical SHA-1 hashes and file size under the "downloads" section. I also calculated the SHA-256 hash with an external utility, and both .jar files have identical hashes. Both versions display "Minecraft Alpha v1.2.1_01" ingame, which suggests that both versions are in fact "a1.2.1_01", despite one of them claiming to be "a1.2.1".

      This strongly suggests that the "a1.2.1" version listed in the launcher is a duplicate of "a1.2.1_01", and should be removed from the launcher, since there is no point in having two copies of the same version listed in the launcher.

      Attatched images are the following: brp1.png compares the .json of "a1.2.1" and "a1.2.1_01", showing the identical SHA-1 hash of the .jr files within the .json.

      brp2.png compares the SHA-256 hash of both of the "a1.2.1" and "a1.2.1_01" .jar files using an external utility (7zip). As you can see, the hashes are identical, which strongly suggests that both "a1.2.1.jar" and "a1.2.1_01.jar" are identical.

      brp3.png shows "a1.2.1" running ingame, displaying "Minecraft Alpha v1.2.1_01". brp4.png shows "a1.2.1_01" running ingame, displaying the same text in the upper left corner.
