A fork of stack-chan/stack-chan, originally created by Shinya Ishikawa and the Stack-chan community. The goal is to provide simple, preconfigured firmware images for a quick start, optimize performance, and keep the fork up to date and in sync with upstream. Fork base: upstream 2.0.1, commit Current source firmware: 2.1.0-R4, for M5StackChan CoreS3. The published stable release is 2.1.0-R4. Preconfigured application-only and full BINs are available in that release. |

Main differences in 2.1.0-R4 compared with upstream 2.1.0:
| Area | What you get |
|---|---|
| Easy installation | Ready-to-use full-install and app-update BINs. App updates preserve settings, MODs and storage on the supported layout. |
| Voice chat and search | GPT-Live 1, Realtime Mini and GPT-Realtime 2.1, all with web search. Start or stop with LIVE or the drawer. |
| Conversation feedback | Dim/bright green shows ready input and incoming speech; purple shows pending work and cyan shows audible replies. Small head movements accompany longer replies on CoreS3 and can resume after a servo error. |
| Personal settings | Added password-protected Wi-Fi Settings alongside Bluetooth. Save instructions, models, thinking effort, separate Live/Realtime voices, pitch and speaking style. |
| Interruption and resume | Enable spoken interruption, with fixes for repeated or stuck replies. Resume Live after idle standby with recent context. |
| Everyday fixes | Fixes for screen/touch handling during chat, camera reopening and recoverable chat errors. |
| USB troubleshooting | Off by default. Enable logs and temporary audio adjustments when needed, without reinstalling firmware or changing saved settings. |
