1. Create a Folder and Installation for the MiniaTuria Mod
- If you want to play Minecraft with mods: → It’s safer to keep your modded environment separate from your regular Minecraft setup ⚠️ → Create a dedicated Minecraft folder just for the MiniaTuria Mod, and keep all your mods, resource packs, and world data inside it. → Then, to launch Minecraft using that folder each time, let’s create what's called an Installation! I’ll walk you through the process.
First, manually create an empty folder anywhere you like (putting it on your C drive might be a good idea). → I made mine on the desktop—it makes it easier to find screenshots and game data later on. → In this guide, I’ll be using the name “MiniaTuria1.12.2.”
- Next, install the official Minecraft Launcher!
⚠️ Unlike the standalone Bedrock Edition, the Java Edition can only be launched through this launcher.→ If you’ve already played Minecraft Java Edition or have the launcher installed, skip this and go to step 4
Go to this page on the official Minecraft website and click “DOWNLOAD FOR WINDOWS” → This will download “MinecraftInstaller.exe.” Open it to start the installation.
→ When this window appears, follow the instructions to install (It's actually in English).
→ Once the launcher (with the Creeper face icon) is installed, open it to launch Minecraft!
→ Launch the Minecraft official launcher → Select "MINECRAFT: Java Edition" → Click on “Installations”
→ Click on "New installation" (You may see many existing Installations, but if it’s your first time, there won’t be any yet)
→ The “Create new installation” screen will open → Enter any name you like in the "NAME" field! Here, we’ll use “MiniaTuria_1.12.2.” → Then, from the "VERSION" dropdown, select “release 1.12.2.” Since it’s an older version, it will be quite far down the list.
→ "GAME DIRECTORY" If you don’t enter anything, it will default to "Use default directory," which means it’s using the regular Minecraft folder. → This isn’t what we want, so enter the location of the folder you created in 2! Click “Browse,” navigate through Explorer to find your “MiniaTuria1.12.2” folder, or
You can also open the “MiniaTuria1.12.2” folder directly, click on the address bar, and copy the path, then paste it in.
→ It's convenient to set the "RESOLUTION" (Minecraft window size) now as well. → You can enter numbers that aren’t in the options. I recommend 1280 x 720, but feel free to adjust it to your preference!
⚠️ Keep in mind that the larger the screen, the heavier Minecraft will be (if Minecraft lags in full screen, try a smaller resolution. It also helps prevent motion sickness).-
⚠️IMPORTANT⚠️ JVM Arguments!
→ Click on “MORE OPTIONS” to expand the lower section → Now we’ll customize the “JVM ARGUMENTS”!
⚠️ JVM arguments are options that allow you to launch Java with detailed settings.Here, we’ll: (1) Increase the maximum memory Minecraft is allowed to use (2) Prevent memory usage from growing too much during gameplay Without these settings, MiniaTuria Minecraft may lag and become unplayable. → First, check how much memory your PC has!Right-click on the taskbar (the one at the very bottom of your desktop) → Open Task Manager (It's actually in English) → Check “Memory” under the “Performance” tab ① shows the total memory installed in your PC In this example: 16 GB ② shows the available memory, calculated by subtracting the memory currently in use. This is important! In this example: 7.4 GB → Choose the setup that best matches your PC from the options below, and paste it into the “JVM ARGUMENTS” box (overwrite any arguments that were already there).
If your PC has 8 GB RAM, and you close browsers and videos while playing Minecraft → Set Minecraft's max memory to 4 GB
-Xmx4G -Xms4G -Xmn512M -XX:+UseConcMarkSweepGC -XX:+CMSIncrementalMode -XX:-UseAdaptiveSizePolicy -XX:MetaspaceSize=512M -XX:MaxMetaspaceSize=512M
If your PC has 16 GB RAM, but you usually only have around 7 GB free → Set Minecraft's max memory to 6 GB
-Xmx6G -Xms6G -Xmn512M -XX:+UseConcMarkSweepGC -XX:+CMSIncrementalMode -XX:-UseAdaptiveSizePolicy -XX:MetaspaceSize=512M -XX:MaxMetaspaceSize=512M
If your PC has 16 GB or more RAM, and you still have plenty of memory available → Set Minecraft's max memory to 8 GB
-Xmx8G -Xms8G -Xmn512M -XX:+UseConcMarkSweepGC -XX:+CMSIncrementalMode -XX:-UseAdaptiveSizePolicy -XX:MetaspaceSize=512M -XX:MaxMetaspaceSize=512M
⚠️ Choose your JVM arguments depending on your play environment, like whether you watch videos while playing Minecraft or close all other apps. You can adjust the memory by changing just the numbers in -Xmx6G -Xms6G (6 is a good recommendation) But never assign more than half of your PC's total memory! Your system might freeze. Do this at your own risk!⚠️ These arguments are based on older Java settings, but they help Minecraft run more smoothly when using MiniaTuria 1.12.2. -
→ Now that the launch configuration is ready, click “Install”.
→ You might see a warning saying this version isn’t the latest and may not be safe?! → This warning refers to online multiplayer safety features for kids. If you understand this, check “Don't warn me...” and click “Play”.
→ You should see an icon for the launch configuration you created. Click “Play” to launch Minecraft!
-
→ Minecraft version 1.12.2 will launch (you can check the version in the area indicated by the arrow).
→ If a folder has been automatically created inside the empty folder you prepared earlier, the launch configuration was successful! → Now, close Minecraft for the time being.
⚠️ It’s important to launch Minecraft 1.12.2 in vanilla (without mods) at least once before installing any mods.
