Knulli Firefly

Privacy Pros: FOSS, no ads, no trackers. Provides a better OS for niche devices like the RG35XX SP

Privacy Cons: Limited OS designed for niche hardware. Does not have security features like VPNs or Uncomplicated Firewall like other full Linux distros without advanced tinkering.

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
