Post Description

Hi HN, I've been working on an open-source, Electron (sorry) app for creating Game Boy games with no-code for a few years now. Recently I've been making some improvements to the inbuilt music editor/tracker and have got it running in the browser as a PWA.

https://www.gbstudio.dev/music

https://music.gbstudio.dev/

It runs entirely client-side (no backend), using the File System Access API where available, and works offline.

The file format is that same as in https://superdisk.github.io/hUGETracker/ so you can take any files made with this and edit them with hUGETracker instead.

And then you can drop these into a GB Studio project to make a quick GameBoy ROM too.

Any feedback is appreciated. Thanks!
