This repo contains a set of official Minecraft Versions which are not included on the official manifest. That means most Minecraft Launchers can not find them and run them.

- Find a version if
Versionsfolder. - Move the folder into
.minecraftor.minecraft/versions Download the files of the version using your launcher using(Just click Launch and your launcher should do it automatically.)Repair Files(补全文件 in Chinese).- Enjoy it.
If it still fail to launch, you should download the jar manually, from the
"downloads"key in yourversion.json. Save with the same name of your json (abc.json+abc.jar in the same folder). And Disable the file check of the launcher. You can add a issue since this is probably my fault...
We also provide a version_manifest.json with the versions included. Inside this .json file, version.json are modified in order to make launchers know where to download the client.jar file.
Copy the jar file into Versions/${ID}, add the ID's version.json(from similar versions), change id downloads.client&sha1&size(use script sha1.ps1).

Unfortunately, this file is hard to be found. So that I've downloaded it on indiedb.com. Although I've checked, you still need to be careful using it. ↩

Although MOJANG uploaded the builds of many Minecraft ancient versions. They didn't upload their
version.json. You may need to use some nearby versions'version.jsonin order to launch these versions. I will try to make some of the versions runable by making jsons. ↩
