In development

Yours to keep.

MUN™ is a console built around physical Game Cards. Each one holds the complete game and your save, and plays without an account or a connection.

The philosophy

The game is the star. MUN is its stage.

  1. Buy.
    Buying a game means owning it again.A legitimate Game Card starts its game with no account and no activation server.
  2. Own.
    What’s yours travels with you.Your saves live on the card and carry on at another console.
  3. Play.
    Insert it and play.No connection and no library to manage. When updates exist, the original version will still be there.

The console In design

MUN OS already boots. This will be its home.

What the virtual console does today will have its place in the object. This is how we are drawing it.

The board Coming soon

One board, the official one.

MUN will have a single official configuration, ARM64. We are working to make it as authentic as it can be; once we choose it, you will see it here.

What decides it

  • Native games
  • Vulkan
  • Useful NPU
  • Temperature
  • Noise
  • Cost
  • Future

Shaping v1 · much more to come

The game beyond the game.

With MUN Shape, each Game Card dresses the console in its game’s identity while it is in.

  1. Its materials The menus and the game’s panel, in the game’s palette and materials. With its sounds and transitions.
  2. Its world Behind the menus, in layers, with light and motion.
  3. Its card The Game Card object, with a window onto its game.

For studios

  • The art that does not fit in the box

    Prototypes, concept art, what could not be printed: the studio decides what to show when its card goes in.

  • Data, not code

    Pictures, sounds and a JSON file. The console draws it with its own code; nothing on the card runs.

  • Works today

    MUN Shape already works in MUN OS, with two examples to start from. And this is only v1: much more is coming.

Games

Coming soon.

Games on Game Cards: to own, lend and keep on a shelf.

The first run of Game Cards will be on microSD: the complete game and your saves travel inside the card.

If you like, you will also be able to buy them online and have an account. All optional: to play, the Game Card is enough.

Development guide MUN OS 0.1.0-dev.3

Boot it on your system.

There is no hardware yet, but MUN OS already starts as a virtual console on macOS, Linux and Windows. Download it and play: no compiling needed.

  1. A Mac with Apple Silicon. QEMU, from Homebrew; the system’s python3 works.

    $ brew install qemu

  2. The tools are MUN OS’s own repository.

    $ git clone https://github.com/Play-MUN/mun-os.git
$ cd mun-os

  3. The image, its Game Cards and their licences; every file is checked.

    $ ./mun get https://github.com/Play-MUN/mun-os/releases/download/v0.1.0-dev.3/release.json

  4. It opens in a window, with sound, and MUN Collect goes in by itself. Enter, Enter: Play. Arrows move, S saves on the card and Esc exits.

    $ ./mun play --card collect

  5. Switch it on again: the save is on the card, not in the console. Turn it off from the menu, with Turn off.

    $ ./mun play --card collect

$ brew install qemu

$ git clone https://github.com/Play-MUN/mun-os.git
$ cd mun-os

$ ./mun get https://github.com/Play-MUN/mun-os/releases/download/v0.1.0-dev.3/release.json

$ ./mun play --card collect

$ ./mun play --card collect

A development image for QEMU, the same on every system. The official hardware configuration is still to be chosen.
