Jeffrey Pfau

Jeffrey Pfau is an independent developer best known for mGBA, a lightweight, cross-platform emulator that re-creates the Nintendo Game Boy Advance hardware on modern Windows, macOS, Linux, and BSD systems. Written with an emphasis on accuracy, speed, and portability, mGBA provides gamers, homebrew authors, and preservationists with cycle-accurate CPU, PPU, and audio emulation, support for save states, controller mapping, ROM patching, cheat-code databases, and real-time debugging tools that rival commercial offerings. Typical use cases include relaunching classic 2000-era titles at higher resolutions, recording tool-assisted speedruns, developing new homebrew cartridges, and validating hardware behavior against documented specifications. The emulator also bundles optional Qt and SDL front ends, a command-line headless mode for automated testing, and built-in connectivity with the Dolphin Wii/GameCube emulator for multiplayer features. Because the codebase is permissively licensed, third-party front ends, libretro cores, and retro-gaming distributions routinely integrate it, while archival projects rely on its documented accuracy to migrate cartridge data to future-proof digital formats. Jeffrey Pfau’s software is available for free on get.nero.com, where downloads are delivered through trusted Windows package sources such as winget, always installing the newest upstream build and permitting batch installation alongside other applications.
