RomM is a self-hosted ROM manager and player for organizing an owned game collection. It scans game folders, parses filename tags and naming schemes, and enriches entries with metadata from IGDB, Screenscraper, and MobyGames, with artwork from SteamGridDB. The interface supports metadata for more than 400 platforms, custom tags, multi-disk games, DLCs, mods, hacks, patches, and manuals. RomM can display RetroAchievements progress and play compatible games in a browser through EmulatorJS and RuffleRS. It supports browsing, uploading, updating, and deleting games through a web browser, sharing a library with limited permissions, and official apps or integrations for Playnite, Android, and custom firmware handhelds.

Obtainium Emulation Pack is a curated collection of Android emulators, gaming utilities, frontends, PC-emulation tools, streaming clients, and related resources maintained as Obtainium app configurations. It provides JSON import files that let Obtainium track and update the included applications, with Standard and Dual-Screen variants that substitute compatible dual-screen emulator forks and utilities. The pack also includes track-only resources, such as driver repositories that do not publish installable APKs; these generate update notifications but must be downloaded and marked updated manually. The repository documents daily testing, automatic flagging of broken configurations, and contributor commands for adding apps, validating APK resolution, and generating the output files.

Escrcpy is an open-source graphical interface for displaying and controlling Android devices through the scrcpy engine. It provides an embedded mirror with screen-fitting and orientation handling, configurable mappings for touch, joystick, swipe, scrolling, and automation, simultaneous control of multiple devices with broadcast input, batch screenshots and APK installation, and a draggable control bar for device operations. It also supports wireless ADB connections with LAN discovery and Gnirehtet reverse tethering, visual step-by-step automation with screen-image recognition, global shortcuts, and an MCP-based AI assistant with multi-model chat. Released packages are available for manual installation, with macOS installation through Homebrew; advanced features from the private EscrcpyX extension are paid, and the project states that updates are irregular.

SuperAstra is a SNES-themed desktop companion that uses natural-language prompts to investigate and alter a running game through BizHawk. Its agent receives screenshots, cartridge identity data, emulator registers, memory scans, hardware-domain reads, controller probes, and checkpoint results; it can search cartridge data, identify game-memory structures, create routines or guarded patches, test changes, and retain cartridge-specific findings in a local notebook. Each committed mutation can be undone through emulator checkpoints, while named experiment checkpoints support controlled trials that restore the player's prior state. The prototype runs on Windows or Linux with Python and Tkinter, BizHawk using its BSNES SNES core, a ROM, and an OpenAI API key configured for the stated model; it also includes limited local Mario shortcuts that do not require an API key. It does not patch the original ROM file, create exportable ROM patches, expand ROM capacity, or guarantee success on unfamiliar games. The original source is MIT-licensed.

An open-source reconstruction of the historically lost B programming-language compiler, developed by Angelo Papenhoff. Its B implementation uses two phases: `bc.b` compiles B source into an intermediate format, and `ba.b` converts that format into assembly; the first phase is mostly platform-independent apart from word size, while the second is platform-dependent. The repository also contains an initial C compiler used to bootstrap the B compiler, capable of producing PDP-11, amd64, MIPS32, and RISC-V 64 assembly, plus reconstructed variants for UNIX v1 on the PDP-11 and ITS on the PDP-10. The compilers generate the original threaded code, with the PDP-10 version using ASCII intermediate code. The project has been confirmed to compile itself on Linux amd64, Linux MIPS32, Linux RISC-V 64, 2.11BSD PDP-11, UNIX v1 PDP-11, and ITS PDP-10.
