KNULLI

KNULLI is a custom firmware for retro gaming devices (handhelds, bartops, etc.). It's developed as a fork of Batocera. You can read more about knulli on its webpage

Installation

• Download the latest version of KNULLI.
• Write the image (e.g. knulli-a133-trimui-smart-pro-40-20240517.img.gz) to an SDCARD using an imaging tool. Common imaging tools include Balena Etcher, Raspberry Pi Imager, and Win32 Disk Imager. If you're skilled with the command line, dd works fine too.

ChangeLog:

20240517

• First TrimUI Smart Pro (TSP) public version (TSP)
• Added joystick calibration: (tSP)
  • calibration files are taken from stock (there's no current calibration program)
  • If the default calibration does not work for you, you can start stock, calibrate the joysticks, connect via ssh or adb, and copy the files joypad.config & joypad_right.config from /mnt/UDISK. Then in Knulli, use ADB or SSH to copy those files to /mnt/UDISK, and run batocera-save-overlay to make the change permanent
