The recommended way to play E36 is with Prism Launcher. First of all, join Discord: it’s linked to the servers, and it’s the place to get help or just hang out.
How it works
The Prism instance downloads nothing up front. Every time you launch it, it first syncs its mods and configs with the server’s pack (using packwiz-installer), then starts the game. Mods removed from the pack are removed from your instance too, which MCUpdater doesn’t always manage. Mods you add yourself are left alone.
Installing
- Install Prism Launcher and log in with your Microsoft account.
- In Prism’s settings, under Java, make sure automatic Java download/detection is on. E36 runs on Cleanroom, like the server, which needs Java 25; Prism will fetch it for you. If you already play E36 through the Cleanroom template in Prism, this is the same setup, except that the mods now update themselves.
- Click Add Instance → Import, and paste this URL:
https://madoka.brage.info/pack/prism/e36/E36.zip - Launch the new E36 instance. The first launch downloads about 400 MB. A window shows the progress and lets you choose the optional mods. Later launches only download what changed.
- The instance gets 6 GB of memory by default. Change it under Edit → Settings → Java if your computer has more or less to spare; going below 4 GB is likely to cause problems.
Connecting
The server only accepts connections from addresses that have been let in. Before connecting:
- Open punch.brage.info on the computer you play from and log in with Discord. You need the Minecraft role on our Discord server, and to be on the whitelist; ask in Discord to get both. If you just got the role, log in to punch again.
- Punch opens the server to your internet address for 14 days. Visiting the page again, or playing, renews it.
- Connect to
minecraft.brage.info.
If you can’t connect after changing network, IP address or VPN, visit punch again.
Bringing your things over from MCUpdater
Copy these from your MCUpdater E36 instance folder (under ~/.MCUpdater on Linux,
%APPDATA%/.MCUpdater on Windows) into the Prism instance’s minecraft folder
(Edit → Folder in Prism): saves/, journeymap/, screenshots/, options.txt and
servers.dat.
Good to know
- If the pack server can’t be reached, the sync window lets you continue and play with what you have.
- If you edit one of the pack’s config files, your edit stays until the pack changes that file; then the pack’s version replaces it.
- If a launch fails at the sync step, please copy the text of the error window into Discord.
Legacy: MCUpdater
The old MCUpdater install still works, but it’s no longer the recommended route. If you already use it, see “Bringing your things over from MCUpdater” above to switch.
To get started:
- Make sure you have 64-bit Java 17 (or newer) installed.
- Download and run MCU-Bootstrap.
- Select the correct instance from the instance list, on the left.
- Take a look at the mods list. Many of these are optional. Defaults have been provided, but use your own judgement.
- Click update
- After you’ve updated the pack and run the link script, you may want to tweak the memory allocation of the pack in PrismLauncher. Default values are provided for the pack when the script creates a linked pack entry, but if you have the RAM for it, more memory may improve performance. Or you could reduce the memory consumption if you are using a weaker computer, though going below a maximum of 4GB is likely to cause problems.
- Click launch.
If you’re lucky, this will let you into Erisia. If not, please make sure you’re actually using 64-bit Java 8; if you aren’t using that, you’re going to need to delete the installation directory before trying again. Otherwise, ask for assistance in Discord.
Depending on your OS, here’s where to find it:
- Linux: ~/.MCUpdater
- OS X: ~/Library/Application Support/MCUpdater
- Windows: %APPDATA%/.MCUpdater
