- You can switch between HDD mode, virtual cdrom mode, and virtual flash drive mode.
- HDD mode - in that mode your Raspberry Pi is basically USB flash drive connected to your computer.
- CD mode - in that mode you select some iso you uploaded to Raspberry Pi in HDD mode, and the rpi will pretend to be that cdrom.
- USB mode - the rpi will pretend to be a flash drive, presenting the usb .img you selected.
- Key1 - Activate selected image
- Key2 - Deactivate image
- Key3 - Change mode
- Joystick Down - next image
- Joystick Up - previous image
- Joystick Left - shutdown / power on
There are customized DietPi images with gadget_cdrom and kernel patch for big isos in the releases section, just write it to sd-card (you can use rpi-imager, dd, etc.), turn rpi on and wait a few minutes to get everything ready.
