1. Create an Installation
-
If you wanna play Minecraft: Java Edition with mods… it’s safer to keep it separate from your regular Minecraft ⚠️
Make a special folder just for MiniaTuria Legacy and put all your mods, resource packs, and world data in there.
And so you can always start Minecraft with that setup, let’s make an Installation! -
Create an empty folder anywhere you like (C: drive is a good choice)
I usually make mine on the desktop (easier to find screenshots and save data)
Use only letters and numbers for the name. In this guide we’ll call it MiniaTuriaLegacy. -
Next, install the official Minecraft Launcher
⚠️ Unlike Bedrock Edition, Java Edition can only be launched from this official launcher.If you’ve already played Java Edition before or already have the launcher, skip ahead to step 4
Go to the official download page and download MinecraftInstaller.exe
Run it and follow the instructions. Once installed, you’ll see the launcher (creeper face icon) — open it up! -
Open the launcher → select MINECRAFT: Java Edition → click Installations
-
Click New Installation (if this is your first one, the list will be empty)
-
The Create new installation screen opens
In Name, type anything you like (here we’ll use MiniaTuria_Legacy)
Under Version, pick release 1.20.1 -
Game Directory
If left blank, it’ll use the default Minecraft folder (your regular game data)
Change this to the MiniaTuriaLegacy folder you created in step 2
Either hit Browse to navigate, or open the folder in Explorer, copy the path from the address bar, and paste it here. -
Resolution (Minecraft window size) can also be set here.
You can type in any value — 1280 x 720 is recommended.
⚠️ Larger screens make Minecraft run heavier. If fullscreen lags, try lowering the resolution (also helps prevent motion sickness) -
For MiniaTuria Legacy, give Minecraft at least 4 GB of memory.
Go to More Options → JVM Arguments. By default you’ll see -Xmx2G. Change the 2 to 4 so Minecraft can use up to 4 GB!
⚠️ If your PC has less than 8 GB of RAM, don’t change this. -
That’s it for setup — click Create
Since Launch after installation is checked, Minecraft will start automatically.
⚠️ To install Fabric later, you must first launch vanilla 1.20.1 at least once. -
Click Continue
Then click Quit Game to close Minecraft for now.
