GB Maker and GBC Maker, two desktop tools for making original Game Boy and Game Boy Color games, can export finished projects in three more formats. Their developer, ArturDuleba, announced the update in a devlog post on 24 October 2026.

The new targets are HTML5, which plays in a web browser, a standalone Windows EXE and a standalone Linux AppImage. Before this, the tools exported ROM files and had a built-in preview, and both of those still work. The point, the developer writes, is to make it easier to share a game instead of only running it inside the Maker. An HTML5 build can go straight onto an itch.io page, so people can play without downloading anything or setting up an emulator.

No branding, no royalties

Exported games carry no GB Maker or GBC Maker branding. You can give a game its own name, icon and look. Both itch.io pages say there are no royalties and no required credits, and that you are free to give your game away or sell it.

The ROM exports still matter for anyone who wants their game on real hardware. According to the GBC Maker page, a .gbc file runs in emulators, on flash cartridges and on a real Game Boy Color.

What the tools are

GB Maker is not a drag-and-drop builder. Game logic is written in its own Lua-like scripting language, and the itch.io page says outright that there is no visual block programming. It bundles a code editor, a sprite editor, a tile-based map editor, a music editor and an emulator for testing in one program, for Windows and Linux.

Both tools are new. GB Maker's first public release went up on itch.io about three weeks before this update and was followed by updates for multiplayer on real hardware and sprite sheet import. GBC Maker's first public alpha, version 0.0.5a, came out about five days before the export update. GB Maker costs at least $5 and GBC Maker at least $6 on itch.io, and GB Maker is listed as in development.

In his post on r/retrogamedev, the developer asked which export format people would like to see next.
