join riseanarchy.org on alpha 1.2.6. server will slowly update through versions. i recommend getting betacraft.uk bc it will fix skins, and usernames. if you dont you will share a acc with someone else lol

Skins don't work in versions below 1.7.5 iirc. You can use the Betacraft launcher to get skins in old versions, as well as correct sounds and all the many versions up to 1.5.2 that are missing from the vanilla launcher

As the other user said, you don't need to log in. In any case it is safe, people wouldn't recommend it otherwise. Make sure to download it from here: https://github.com/Moresteck/BetaCraft-Launcher-Java/releases

Use the Betacraft launcher. It's specifically made for playing old versions and includes ALL the archived versions up until 1.5.2 (many are missing from the vanilla launcher, including all of Indev and all snapshots before 1.5).

Note that like many old mods this is a "jar" mod which is installed directly into the Minecraft jar; I've read that on the Betacraft launcher you can just directly modify it (make a backup of the jar, then extract the zip and add the files to the jar using a tool like 7Zip or WinRar, also delete the META-INF folder inside the jar), though MultiMC lets you add mods to the jar without having to manually modify it (Betacraft includes many other fixes for old versions though, and may even eventually include the M1 Mac fix).
