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-h700-rg35xx-plus-40-20240530.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:

20240530

• First public release for the RG35XX Plus/H/2024 and SP (hinge support is not there yet)
• Fixed issue with progressbar application that was not stopping after boot
• Set default overclock to 1.5GHz for the H700 platforms (same as stock). All other values are "underclocks"
• Set HDMI frequency to 60Hz for TV compatiblity (thanks @loki666)
• Set initial set of drastic mappings
• Fixed incorrect Drastic menu mappings (thanks @Mikhailzrick)
• Reverted retroarch back to use mali_fbdev context driver. This fixes performance issues as well as a memory leak that was impacting several emulators like SNES, GBA, etc and causing audio stuttering and crashes
• Changed S12populateShare to default to KNULLI version
• Bumped rtl8812au to fix bluetooth issues, included BT audio (thanks @Nerdy-boi)
• Updated Art Book Next (thanks @anthonycaccese )
• Added additional fixes to tate mode by @Mikhailzrick

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
