What you are hosting
MeatballCraft: Dimensional Ascension is described by its creator as an “expert-level tech-RPG modpack.” It targets Minecraft 1.12.2 and Forge. The official manifest identifies Forge 14.23.5.2860 and recommends 8,736 MB of RAM. The current server-pack filename listed by the CurseForge project is Meatballcraft-Server-prerelease-0.18.6.4.zip, dated August 16, 2026.

The pack is still labelled pre-release. Its project description says that all content is available and all endings can be reached, but a pre-release can still change between server-pack versions. Treat the server pack and every client installation as one versioned set.
Choose a hosting method
There are four practical ways to run the pack. Your choice determines who manages files, backups, networking and Java.
#1 Best Overall
| Method | Setup effort | Control | Backups and updates | Networking and cost |
|---|---|---|---|---|
| Ordinary self-hosting | Moderate: download, extract and run the supplied files | Maximum control over files, JVM arguments and configuration | You create and test backups and updates | You manage firewall and router exposure; hardware and electricity are your responsibility |
| Managed hosting panel | Lowest: install the pack from a panel | Panel-level file and setting access; JVM control varies | Automation and scheduled-backup options may be available | Provider handles the public endpoint and infrastructure; recurring hosting charge applies |
| Docker | Moderate to high: compose file, image and persistent volumes | Repeatable container configuration and command-line control | Repository script supports backups; you must pin and update the image deliberately | You still manage host networking and the Docker host; infrastructure cost remains yours |
| Cleanroom MMC | High and experimental | Alternative server runtime and Java path | Use the same backup discipline, with extra migration risk | Same network responsibility as self-hosting |
For a first server, use the ordinary server-pack launcher. Docker is useful when you already operate containers. Cleanroom is an optional performance experiment, not the safest starting point.
Plan the machine before installing
Memory
The manifest’s 8,736 MB figure is the pack’s official recommendation. It is memory assigned to the Java process, not necessarily the total physical RAM in the computer. Leave room for the operating system, Java overhead, storage services and monitoring.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
| Concurrent players | Planning range | How to use it |
|---|---|---|
| 1–5 | 6–8 GB | Start near the upper end if the world contains automation-heavy bases or many loaded chunks. |
| 5–15 | 10–12 GB | Reserve additional system memory so the host does not swap. |
| 15+ | 12–16 GB | Treat this as a starting range, not a player-count guarantee; measure tick performance under real load. |
The player ranges above are planning guidance from a dedicated Minecraft hosting specification, while 8,736 MB comes from the MeatballCraft manifest. No official pack source publishes a universal CPU model, storage size, bandwidth requirement or guaranteed player count.
Java and Forge
The canonical pack information specifies Minecraft 1.12.2 and Forge 14.23.5.2860 but does not publish one universal Java version for the ordinary server launcher. Use the Java runtime supported by the included launcher and your operating system, and verify that the launcher is invoking that runtime rather than a different system installation. Do not assume that the optional Java 22 instructions apply to the standard pack.
Java 22 appears in the separate Cleanroom MMC route. That route replaces part of the normal Forge server and is explicitly described as still being tested, so keep an untouched ordinary server-pack copy available.
Storage, CPU and network
- Use a dedicated folder on fast local storage and keep the live world separate from the downloaded client instance.
- Choose a machine with sustained CPU capacity rather than judging it only by core count. Modded 1.12.2 servers can be limited by one busy tick thread.
- Use a stable wired connection when possible. The pack sources do not specify a bandwidth number; actual demand depends on view distance, exploration and player activity.
- Do not expose the server until the whitelist, firewall and backup process work.
Install the ordinary MeatballCraft server pack
1. Download the matching server archive
- Open the official MeatballCraft project on CurseForge and download the server-pack ZIP listed for the release you intend to run. For the current listing, the filename is
Meatballcraft-Server-prerelease-0.18.6.4.zip. - Create a dedicated directory such as
MeatballCraftServer. Do not extract the server over a client instance or another modpack. - Extract the complete ZIP into that directory. Keep the supplied Forge files, libraries, configuration folders and scripts together.
Do not mix a server pack from one release with mods or configuration copied from another. Record the filename and download date in a small text file so you can identify the live version during maintenance.

One-click scans. No signup required.
2. Run the supplied launcher once
- Start the included Windows launcher or Linux shell script from the server directory. Run it from that directory so relative paths resolve correctly.
- On the first launch, Minecraft normally stops and asks you to accept the EULA. Open the generated EULA file, read the terms, and change the acceptance setting only if you agree.
- Run the same launcher again after accepting the EULA. The second run generates the world, server properties and configuration files.
- Stop the process cleanly after generation, then start it again and watch the console for a completed startup message. A force-kill during first generation can leave incomplete files.
The MeatballCraft sources do not publish a separate EULA procedure; the prompt is standard Minecraft server behavior. If the launcher immediately exits, run it from a terminal or command prompt so the error remains visible, then check the Java path and the extracted directory structure.
3. Set basic server properties
Open server.properties only after the first successful generation. Set a sensible maximum player count, difficulty and view distance for your hardware. Make one change at a time and restart the server after editing. Keep command blocks disabled unless your map or administration workflow requires them.
For a small private server, a conservative starting point is the managed-host profile documented for this pack: max-players=10, difficulty=normal, view-distance=10, simulation-distance=8, and enable-command-block=false. Reduce view or simulation distance if the server cannot maintain its tick rate.
Install the client and connect locally
- Install the exact same MeatballCraft release and Forge profile on every player’s computer. The Minecraft version, Forge build, mods and configuration must match the server.
- Start Minecraft with the MeatballCraft: Dimensional Ascension profile.
- For a test on the same home network, use the server computer’s local address. The server operator can find that address with the operating system’s network settings; it is not the public address shown to Internet players.
- Join through Multiplayer and confirm that a player can move, open inventories and load a new area before inviting people outside the home.
A client that has a different modpack release, Forge build or configuration may fail during the handshake, disconnect while loading, or produce missing-mod errors. Reinstalling the exact client release is usually safer than copying individual files from a different instance.

Let friends join over the Internet
What you must configure
An Internet server needs a reachable public endpoint. That normally means allowing the Minecraft server through the host firewall and forwarding the listening port from the home router to the server computer. The canonical MeatballCraft sources do not specify a universal port number or router procedure, because those values vary by operating system, router model, ISP and any hosting panel in use.
- Give the server computer a stable private address, either with a reserved DHCP lease or a static network configuration.
- Allow the server process through the host firewall on the chosen protocol and port.
- Create a router forwarding rule from the external port to the server computer’s private address and the server’s listening port.
- Test from a network outside your home, such as a phone hotspot. Testing only from inside the same LAN can hide NAT or forwarding mistakes.
- Share the public address and port privately, not in a public post.
Some ISPs use carrier-grade NAT, which prevents inbound forwarding. If an external test cannot reach the server despite correct local settings, ask the ISP whether inbound connections are available or use a managed host instead.
Protect a private server with the whitelist
From the server console, enable the whitelist and add each player’s Minecraft username:
whitelist on
whitelist add YourUsername
whitelist add FriendUsernameThe managed setup instructions use this same sequence. Add the operator account before enabling the whitelist so you do not lock yourself out. Remove old names when accounts change, and keep the list as the primary access control rather than relying on an undisclosed address.
Recommended Free Tools
Use a managed hosting panel
A managed host is the simplest route when you do not want to administer a router, operating-system firewall or physical machine. Providers that support Forge/Minecraft 1.12 installations may offer one-click pack installation, dedicated CPU and RAM, NVMe storage and DDoS protection. Those are provider claims, not guarantees for every plan, so check current terms, limits, backup retention and pricing before paying.

Typical panel sequence
- Create the server and select the MeatballCraft pack or upload the matching server pack if the panel does not list it.
- Wait for the panel’s automatic installation to finish. Do not start the server while files are still being unpacked.
- Set
max-players=10,difficulty=normal,view-distance=10,simulation-distance=8andenable-command-block=falseas conservative initial values. - Open the console and run
whitelist on, followed bywhitelist add YourUsernameand one command for each friend. - Start the server and copy the IP address and port shown by the panel.
- Install the identical MeatballCraft client release and join using that panel endpoint.
Before inviting players, locate the panel’s stop, console, file manager, restore and scheduled-backup controls. Confirm whether backups include the complete world and configuration or only selected files.
Run MeatballCraft with Docker
The community ramity/meatballcraft repository documents a Docker Compose workflow. It is appropriate when you already understand persistent volumes, image tags and host firewall rules.
- Clone or download the repository on the Docker host and review its Compose file, environment variables, volume mappings and exposed ports.
- Pin a known-good image tag or digest instead of silently tracking an untested latest build.
- Start the stack from the directory containing the Compose file:
docker compose up -d- Check container logs and confirm that the world reaches a ready state.
- Use the documented RCON command wrapper for administration:
docker exec meatballcraft rcon-cli- Schedule and test the repository’s backup script:
./scripts/backup.shStore backups outside the container’s writable layer. Rebuilding a container must not delete the world, whitelist or configuration. Review the Compose files before exposing ports, and test restoring a backup to a separate container before treating the process as reliable.
Optional Cleanroom MMC and Java 22 path
The MeatballCraft wiki documents a performance-oriented Cleanroom MMC procedure, but explicitly warns that the instructions are still being tested. Use it only after the ordinary server-pack path works and after making a full copy of the world.
- Download and extract the normal server files into a working copy.
- Remove the
librariesfolder,forge-1.12.2-14.23.5.2860.jarandminecraft_server.1.12.2.jar. - If present, remove
!mixinbooter,MixinCompatandconfiganytime. - Run the Cleanroom MMC server installer.
- Copy
forge_early.cfgas directed by the wiki and set the Java executable path insettings.cfg. - Start with
CleanroomStart.baton Windows or the supplied Linux Java command.
Keep the untouched ordinary server directory as a fallback. If the Cleanroom server fails to load a mod, generates errors during world startup or behaves differently from the standard runtime, stop testing on the live world and return to the known-good copy.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Monitor performance instead of guessing
RAM allocation alone does not determine whether a modded server is healthy. Watch the console for repeated errors, observe whether players experience delayed block updates, and check tick performance with the diagnostic tools available for your server environment. A server that remains full on memory but misses ticks needs CPU, simulation-distance or world-load investigation rather than simply more RAM.

- Keep operating-system swap from becoming the normal source of Java memory. Swapping produces severe latency even when the process appears to have enough configured RAM.
- Do not allocate all physical memory to Java. Retain headroom for the operating system, file cache, Docker or panel agents, and backups.
Backups, updates and rollback
Back up before every change
Stop the server cleanly before copying the world, or use a backup method that is explicitly safe for a running server. Include the world, server.properties, whitelist files, configuration folders and any scripts or environment files needed to recreate the instance. Keep at least one backup on a different disk or machine.
The Docker repository supplies ./scripts/backup.sh. Managed hosts may offer scheduled backups, but verify retention and restoration yourself. A backup that cannot be restored is not a recovery plan.
Update on a test copy
- Record the current server-pack filename and make a complete backup.
- Copy the world into a separate test directory and install the candidate server pack there.
- Start the test copy, inspect errors and let each player verify key machines, dimensions and progression.
- Only after the test succeeds, schedule downtime, back up the live instance again and replace the live files.
- Keep the previous pack and backup until the new world has been played successfully.
CurseForge warns that automatic updates can reset waypoints and keybinds. Its update guidance recommends creating a new profile and copying saves, journeymap and options.txt when updating a client. Apply the same caution to server-side configuration: copy only known-compatible files instead of overwriting the new pack indiscriminately.
Troubleshoot the common failure points
| Symptom | Likely cause | Action |
|---|---|---|
| Launcher closes immediately | Wrong working directory, Java path or incomplete extraction | Run the supplied script from a terminal, verify the ZIP was fully extracted and confirm which Java executable it calls. |
| EULA prompt repeats | The file was edited in a different directory or the server cannot write changes | Stop the process, edit the EULA file generated beside the launcher, check permissions and start again. |
| “Missing mods” or handshake failure | Client and server releases, Forge builds or configuration differ | Install the exact same MeatballCraft release and Forge profile on the client; do not mix individual mod versions. |
| Friends cannot connect, but LAN works | Firewall, router forwarding, changing private address or carrier-grade NAT | Reserve the host’s private address, verify the firewall rule, test from an outside network and confirm inbound service with the ISP. |
| Players are disconnected during exploration | Chunk-generation load, insufficient CPU headroom or excessive distances | Reduce view or simulation distance, close competing services, and observe tick performance before increasing RAM. |
| Whitelist blocks the operator | Operator username was not added | Use the console to run whitelist add YourUsername, then reconnect. |
| Cleanroom copy fails while ordinary server works | Experimental runtime conversion or incompatible Java/mod setup | Restore the untouched ordinary server-pack copy and treat Cleanroom as a separate test environment. |
Security and maintenance checklist
- Pin one exact client and server release and write it down.
- Use a whitelist for any private server.
- Give operator privileges only to trusted accounts.
- Expose only the server port you need; keep RCON and administrative panels off the public Internet unless protected.
- Back up before changing mods, Forge, Java, configuration or world files.
- Test a restore on a copy, not on the only live world.
- Leave memory for the operating system instead of assigning every gigabyte to Java.
- Test updates and new runtimes on a copied world first.
Recommended starting configuration
For most small groups, the least risky sequence is: run the official server pack on a dedicated machine or managed panel, allocate close to the manifest’s 8,736 MB while retaining system headroom, begin with the documented distance and difficulty settings, enable the whitelist, and test two clients before opening Internet access. Move to Docker when you need repeatable container operations. Try Cleanroom MMC only with a tested backup and a working ordinary-server fallback.
