Single-game files

.bin.hex
Compiled gameAdd one game per file, ready to customize and package.
.chg
Game + metadataOne game with title, author, version, and optional cover art. SD data files are separate.
.elfPLAY ONLY
Emulator onlyOpen one at a time. To package your game, export a .bin or .hex instead.

.chgame

READY TO SHARE

One format for all three:

Game
Game with SD
Multi-game cart

Includes the games, metadata, artwork, and SD files packaged inside.

Single games add to your current cart, with their included files.
Multi-game carts let you choose: load the new cart or append its games.

Your games, right here.

Drop files anywhere on this page, or choose them below. Drop several games or carts together to combine them into one working cart.

.chgame
A complete cart: one game or a whole collection, with its artwork and assets.
.bin.hex
Compiled CHGame games from Arduino. Ready to play, customize, and package here.
.chg
One game with metadata and optional cover artwork for the hardware’s SD menu. SD data files are separate.
.elf
A compiled executable for playback only. Open one at a time.

Made your own game?

In Arduino, save your sketch and choose Sketch → Export Compiled Binary. Then use Sketch → Show Sketch Folder and look for the exported .bin or .hex file there or in its build subfolder.

Drop your .bin here and this online tool will prepare a playable, shareable cart. Or prepare your game offline with the CHGame Python tool (chgpack.py / chgame pack) to make a .chg file; the board package can also generate one during a build.

Single games are added to your current cart. For a multi-game .chgame, choose whether to load the new cart or append its games. Artwork is attached separately in the builder; Arduino source sketches (.ino) must be compiled first.

ZIP is for your SD card

.chgame is the recommended format for publishing and sharing games.

This ZIP contains files intended to be copied directly onto an SD card. When distributing your game or cart, best practice is to publish the .chgame file.
