Ω GTi simulator

GUITION JC3248W535 · ESP32-S3
Tap and drag on the screen with your mouse or finger. This is the actual firmware: the boot intro, the library scan, the cover reel, Settings, the search keyboard, the manual reader, the screensavers and SD ACCESS all run exactly as on the board. Nothing leaves your browser.

Pick an SD card for the GTi. Your own folder stays on your computer: the simulator reads the files in your browser and never uploads anything.
