National Video Games Day 2026: Build Your Own Gaming Home Server

National Video Games Day 2026 fell on September 12. Instead of celebrating it with another list of games to buy, there is a more interesting home-server project: build the part of your gaming stack that you can actually own and run yourself.

A home server does not need to replace a gaming PC. It can do three more realistic jobs: keep a retro library and saves in one place, turn one gaming machine into a streamable host, or keep a private multiplayer world online without renting another server.

What Can a Home Server Actually Do for Gaming?

The first useful distinction is between serving games and rendering games.

That separation is important because many gaming projects do not need a powerful GPU at all. Storage, game metadata, save backups and most dedicated servers are fundamentally home-server workloads. Real-time AAA rendering is not.

1. Build One Retro Game Library Instead of Copying ROMs Between Devices

The cleanest gaming use case for an always-on server is a central retro library.

RomM is a self-hosted game-library manager that scans and organizes game files, retrieves metadata and artwork, supports multiple users and integrates browser playback through EmulatorJS.

The more useful feature is not the cover-art interface. It is that the library, metadata and save data can stop living independently on every laptop, desktop and handheld.

Home server
├── Game library
├── Artwork and metadata
├── Saves and save states
└── RomM
     ├── Desktop browser
     ├── Laptop
     ├── Handheld
     └── Tablet

RomM's current EmulatorJS integration can write game saves and save states back to the server, so supported saves can follow the user across browsers and devices rather than remaining attached to one client. Browser emulation still runs on the client device, which means poor emulation performance is not automatically a reason to upgrade the server.

This distinction matters when sizing a retro server. A lightweight server may be perfectly capable of storing and serving the library while a weak tablet still struggles with a demanding PSP or Saturn core.

ZimaSpace already has a useful example of the broader idea. In one real retro gaming home server build, the same compact machine was used as both a self-hosted server and a retro-gaming project rather than buying two separate systems.

That specific build eventually used Fedora Server and RetroPie, so it should not be read as a claim that ZimaOS itself replaces a desktop emulation OS. The more reusable lesson is the architecture: storage and always-on services can coexist with a gaming workload when the roles are clearly separated.

For users staying on ZimaOS, RomM is the cleaner server-oriented route. It is currently available through the ZimaOS app ecosystem, while browser-side tools such as EmulatorJS keep much of the actual emulation workload on the client. The EmulatorJS hardware requirements make that boundary especially clear: server hardware mainly serves ROMs and assets; the browser performs the emulation.

2. Stream One Gaming Host to a Cheap Handheld

The second scenario is almost the opposite. Instead of moving games onto every device, leave the game on one capable host and move only the screen and controller input.

Sunshine is a self-hosted streaming host for Moonlight. The host runs the game and encodes the video; Moonlight receives the stream on another PC, TV, phone or handheld.

ZimaSpace has already documented a real implementation rather than only describing the idea.

In SjslTech's portable PC game-streaming build, the path was:

Windows gaming host
      ↓
   Sunshine
      ↓
   Tailscale
      ↓
   Moonlight
      ↓
 R36S handheld
      ↑
controller input

The R36S did not run the Windows game locally. The host ran and rendered it, Sunshine encoded the session, Moonlight decoded it on the handheld, and controller input travelled back to the host.

This is a much more useful model for low-cost clients. A handheld does not need enough CPU or GPU power to run the PC version of the game if it can decode the video stream reliably.

It also reveals the actual bottlenecks.

This is why adding Tailscale does not make an underpowered machine faster. It solves reachability, not rendering.

On the local network, Sunshine and Moonlight can work without Tailscale. When the client leaves home, a private network becomes much more useful. ZimaOS now documents Tailscale and WireGuard remote access directly, making the same network layer useful for gaming as well as normal home-server access.

The important design rule is simple:

prove the game works on the host, then prove local streaming works, and only then add remote networking.

That sequence makes debugging much easier than configuring game performance, Sunshine, Moonlight and remote access at the same time.

3. Keep a Private Multiplayer World Online Without Renting Another Server

Game streaming requires the host to render the game. A dedicated multiplayer server usually does not.

That makes dedicated servers a better fit for many always-on home servers.

A Minecraft server, for example, is primarily maintaining world state, players, chunks and network sessions. It does not need to render every player's view with a gaming GPU.

The same principle applies to many other titles that publish dedicated-server software or can run through a maintained server container.

This is where ZimaOS's Docker model becomes useful. If a game server has a reliable Docker image or Compose deployment, it can follow the same path as another self-hosted application. ZimaOS supports App Store deployments as well as custom Docker apps on ZimaOS when a service is not already packaged.

A practical gaming stack might therefore look like:

ZimaOS home server
├── Minecraft / game server container
├── Persistent world data
├── Scheduled backups
└── Tailscale
      ↓
  Trusted players

There are two checks to make before doing this.

Check whether the game can actually be self-hosted

Not every multiplayer game exposes dedicated-server software. Some depend entirely on publisher infrastructure. No amount of Docker configuration will turn those games into self-hosted servers.

Check the game-specific CPU and memory requirement

"No GPU required" does not mean "no performance requirement." Modded Minecraft worlds, simulation-heavy servers or large player counts can demand strong single-thread CPU performance and substantial RAM.

Size the machine for the specific game instead of using one generic "gaming server requirements" number.

Use a Private Network Before Opening More Gaming Ports

A private server also needs a way for friends outside the house to reach it.

The traditional solution is router port forwarding. For a small trusted group, it is not always necessary.

Tailscale's private game-server workflow allows approved devices to reach a server through a tailnet instead of intentionally exposing the game port to everyone on the public internet.

Public model:

Internet
   ↓
Open router port
   ↓
Game server


Private model:

Approved device
   ↓
Private tailnet
   ↓
Game server

This is particularly attractive for a persistent world shared among a few friends.

It is not automatically the best architecture for a large public community server, and some games have unusual discovery or networking requirements. But it is a useful option to evaluate before making another home service publicly reachable.

Do Not Forget the Most Valuable Gaming File: Your Save

A game installation may be downloadable again. A 150-hour save may not be.

Ludusavi is designed specifically for this problem. It currently supports backup and restore data for more than 19,000 games across Steam, GOG, Epic, Heroic, Lutris and other PC libraries.

Instead of manually remembering that one game stores progress under Documents while another hides it in AppData or a Proton prefix, Ludusavi uses a game manifest to locate relevant files.

A simple home-server workflow is:

Gaming PC
   ↓
Ludusavi
   ↓
Versioned backup folder
   ↓
Home server storage

The word versioned matters.

A live synchronized folder alone is not the same as a backup. If a corrupted or accidentally deleted save is immediately synchronized to the server, the server may simply receive the damaged copy.

Ludusavi supports retained full and differential backups, making it more useful for this job than treating every save directory as a single mirrored folder.

Which Gaming Project Should You Build First?

If you already own a home server, there is little reason to start by buying new gaming hardware.

Start with the layer your current setup is missing. Centralize the library. Protect the saves. Keep one multiplayer world online. Or make one capable machine accessible from lighter devices.

The Better Gaming Server Is Infrastructure, Not Another Console

National Video Games Day is usually framed around what to play. For home-server users, the more useful question is what happens to the game after you have played it for 100 hours.

Where is the save? Where is the private world? Can another device reach the library? Does playing remotely require exposing another port? What happens when the gaming PC is replaced?

A home server is useful precisely because it can keep those layers separate from the device currently drawing the frames.

Home server
├── Library
├── Saves
├── Multiplayer worlds
└── Private networking

Gaming host
└── Heavy rendering + encoding

Clients
├── Browser
├── Laptop
├── TV
└── Handheld

That is a more durable way to think about gaming at home: the console or gaming PC becomes one endpoint, while the parts worth keeping live on infrastructure you control.

FAQ

When was National Video Games Day 2026?

National Video Games Day was observed on September 12, 2026. Historical research by the Video Game History Foundation found that July 8 and September 12 originated from the same observance, whose date changed several times before September 12 became established.

Can I use a home server as a gaming server?

Yes, for workloads such as retro game libraries, save backups and supported dedicated multiplayer servers. Running modern PC games directly is a different workload and may require much stronger CPU and GPU hardware.

Does RomM need a gaming GPU?

No. RomM manages the library on the server, while its EmulatorJS integration performs emulation inside the client browser. A stronger server does not automatically improve emulator FPS on a weak client.

Can I stream PC games from a home server?

Yes, if the host itself can run the game and encode the stream. Sunshine can host the session and Moonlight can receive it on another device. Streaming does not remove the CPU or GPU requirement from the host.

Can I host a private game server without port forwarding?

For compatible games and a small trusted group, a private network such as Tailscale can provide access without deliberately exposing the game-server port to the public internet. Game-specific networking requirements still need to be checked.

What should I back up from my gaming PC?

Game saves should be a priority because reinstalling a game usually cannot recreate lost progress. Ludusavi can identify save locations for more than 19,000 games and create retained backups that can be stored on a home server.
