Major Update

This version of KNULLI comes with a lot of new features which require to re-flash the firmware.

We strongly recommend to simply start over with a clean install. However, if you want to try migrating your user data from a previous installation to the new installation, please have a look at the Major Updates guide.

If you are new to KNULLI and want to get started: Head to the Quick Start Guide on our website - it will guide you through the installation and your very first steps. If you are already running KNULLI and want to upgrade to Gladiator: Be aware that the PortMaster and exFAT situation is pretty much resolved which is why KNULLI defaults to exfat now! Might be a good time to start with a brand new setup?

In any case: We hope you enjoy playing your games with KNULLI!

About KNULLI

KNULLI is a custom firmware for retro gaming devices (handhelds, bartops, etc.). It's developed as a fork of Batocera. It tries to provide support for devices that fall under at least one of these categories:

  • There are no open-source kernel and/or u-boot sources available
  • There are sources, but the kernel is either not mainline, and/or too old (e.g. devices with a BSP kernel 3.4 like the Egret II Mini)
  • There is no GPU support or the GPU is not supported, so framebuffer is the only option
  • It's a device that we own and have decided to build a CFW for it

Features

KNULLI supports devices with GPU (GLES support) and framebuffer only (legacy).

  • Emulation Station frontend for GPU based devices
  • Simplemenu/Simplermenu+ for framebuffer only devices (also for GPU ones if preferred)
  • RetroArch plus multiple libretro cores
  • Wireless and Bluetooth support (including audio) when supported by the device
  • Support for external USB wireless for those without internal wireless card
  • Retroachievments
  • Netplay
  • Cover art/thumbnail scraper support
