Hello, this is Amatarou
This time, as the title suggests, how to play the old version with Micra.
By the way, this can not be done other than Micra Java version (because there is no Minecraft Launcher other than Java version)
First, launch Minecraft Launcher and click "Installation" on the upper tab
(The one at the top of this window is a tab)
Then you will see this screen
At first there should only be "Latest release" here
Then check the old version of the upper right version (although the main is already checked)
Once checked, click + New at the top left.
Then select a version and choose the version you want to play
Please give the person who wants to name (input field at the top)
Then press the lower right corner and you are ready
Then play the tab again
Then, in the lower left selection field, select the configuration you just made and press the play button, you are ready.
When ready, go to the play tab
Then select the configuration of the name entered from the lower left selection run
Then press the play button and you're done.
