OpenRGB
Open source RGB lighting control
OpenRGB is a cross-platform, vendor-agnostic RGB lighting controller that frees you from proprietary motherboard or peripheral utilities. It talks directly to supported devices and exposes a unified interface for setting colors, animations, and per-LED layouts across brands. The app supports running as a standalone GUI, a headless server, or a networked client so multiple machines can synchronize lighting. Profiles make it easy to save and switch complex scenes, and a graphical LED map helps craft precise patterns. Power users can automate everything via a command-line tool and an SDK that third-party apps can target. The project’s goal is straightforward: one tool to orchestrate all your lighting without the bloat, drivers, or background processes that often come with vendor software. -

DuckStation
Fast PlayStation 1 emulator for x86-64/AArch32/AArch64
DuckStation is an simulator/emulator of the Sony PlayStation(TM) console, focusing on playability, speed, and long-term maintainability. The goal is to be as accurate as possible while maintaining performance suitable for low-end devices. "Hack" options are discouraged, the default configuration should support all playable games with only some of the enhancements having compatibility issues. A "BIOS" ROM image is required to to start the emulator and to play games. You can use an image from any hardware version or region, although mismatching game regions and BIOS regions may have compatibility issues. A ROM image is not provided with the emulator for legal reasons, you should dump this from your own console using Caetla or other means. DuckStation features a fully-featured frontend built using Qt, as well as a fullscreen/TV UI based on Dear ImGui. -

FEX
A fast usermode x86 and x86-64 emulator for Arm64
FEX allows you to run x86 and x86-64 binaries on an AArch64 host, similar to qemu-user and box86. It has native support for a rootfs overlay, so you don't need to chroot, as well as some thunklibs so it can forward things like GL to the host. FEX presents a Linux 5.0 interface to the guest, and supports both AArch64 and x86-64 as hosts. FEX is very much work in progress, so expect things to change. FEX has been tested to build and run on ARMv8.0, ARMv8.1+, and x86-64(AVX or newer) hardware. ARMv7 and older x86 hardware will not work. Expected operating system usage is Linux. FEX has been tested with Ubuntu 20.04, 20.10, and 21.04. Also Arch Linux. AArch64 hosts require a rootfs for running applications. -

ESP8266 core for Arduino
ESP8266 Arduino Core is the Arduino core for the ESP8266 WiFi chip. It brings support for the ESP8266 chip to the Arduino environment, allowing you to write sketches, use familiar Arduino functions and libraries, and run these directly on ESP8266 without the need for an external microcontroller. ESP8266 Arduino core comes with libraries that enable it to perform a number of things. It can communicate over WiFi through the use of TCP and UDP; it can set up HTTP, mDNS, SSDP, and DNS servers; and it can perform OTA updates. ESP8266 Arduino core works with SD cards, servos, SPI and I2C peripherals. -

Xenia Canary
Xbox 360 Emulator Research Project
Xenia Canary is an experimental fork of the Xenia Xbox 360 emulator that moves faster than the mainline project to trial bleeding-edge improvements. It focuses on game compatibility and performance by iterating quickly on GPU and CPU emulation paths, shader translation, and timing correctness. Canary builds are where risky optimizations, new backends, and rewrites land first so they can be tested by a wider community before stabilizing. The project emphasizes pragmatism: make more titles boot and run with fewer glitches, even if it means carrying experiments that later get refined or rolled back. It also prioritizes developer ergonomics with logging options, debug overlays, and issue templates that help narrow down regressions. While aimed at enthusiasts and testers, it remains a valuable way for end users to play otherwise inaccessible 360 titles on PC when the mainline is lagging behind those fixes. -

Udp2raw-tunnel
Turns UDP traffic into encrypted UDP/fakeTCP/ICMP traffic
A tunnel which turns UDP traffic into encrypted fakeTCP/UDP/ICMP traffic by using Raw Socket, helps you bypass UDP FireWalls(or unstable UDP environment). When used alone, Udp2raw tunnels only UDP traffic. Nevertheless, if you used udp2raw + any UDP-based VPN together, you can tunnel any traffic(include TCP/UDP/ICMP), currently, OpenVPN/L2TP/ShadowVPN and tinyfecVPN are confirmed to be supported. Linux host (including desktop Linux,Android phone/tablet,OpenWRT router,or Raspberry PI) with root account or cap_net_raw capability. ICMP/FakeTCP headers help you bypass UDP blocking, UDP QOS or improper UDP NAT behavior on some ISPs. In ICMP header mode,udp2raw works like an ICMP tunnel. UDP headers are also supported. In UDP header mode, it behaves just like a normal UDP tunnel, and you can just make use of the other features (such as encryption, anti-replay, or connection stalization). -
