.jar help
How do I install a custom Minecraft .jar file in Minecraft Launcher? Just opening the .jar file won't work and even with a .json, it still didn't work. I am trying to play Alpha v1.1.1 on the Minecraft Launcher by installing it so how?

Alright I got it but where to put the .json in a MultiMC instance
i would recommend using an alternative launcher that has those versions easy to download and run, I use MultiMC there are other launchers out there that re-skin multimc and add to it. you can select what version you wish to download and play minus some missing versions that no one has access to
well sorry im not sure how to help but you can read some articles online about how to make a custom version. :)
