    Retrobios

    Retrobios

    Complete BIOS and firmware packs for RetroArch, Batocera, Recalbox

    Retrobios is a low-level systems programming project focused on recreating or emulating BIOS-like functionality for legacy or experimental computing environments. It is designed to provide a minimal firmware layer that initializes hardware and prepares systems to boot, often used for educational purposes or retrocomputing experiments. The project likely explores how early computing systems managed hardware abstraction, memory initialization, and device communication before modern operating systems take control. It emphasizes simplicity and transparency, allowing developers to study and modify core boot processes at a granular level. The architecture is typically close to bare metal, requiring knowledge of assembly language and hardware interfaces. It may also serve as a foundation for building custom operating systems or experimenting with low-level system design. Overall, retrobios functions as a learning and experimentation platform for understanding foundational computing concepts.

    vJoy
    This project was originally designed to provide an open-source replacement for PPJoy. The product, at this point, consists of virtual joystick devices that is seen by the system as a standard joystick but its position-data is written to it by a feeder application. An existing feeder application that takes advantage of this product is SmartPropoPlus. If you are an application writer you can very easily write an application that controls a joystick (e.g. mouse-to-joystick, keyboard-to-joystick). If you are a beginner in device drivers you can take this code and enhance it to support more (or less) axes, buttons or POVs.
