Open Source Assembly Software

ReactOS is an open source effort to develop a quality operating system that is compatible with applications and drivers written for the Microsoft Windows NT family of operating systems (NT4, 2000, XP, 2003).

PICSimLab is a realtime emulator of development boards with MPLABX/avr-gdb debugger integration. PICSimLab supports microcontrollers from picsim, simavr, uCsim, qemu-stm32, qemu-esp32, and gpsim. PICSimLab has integration with MPLABX/Arduino IDE for programming the microcontroller's boards. As the purpose of PICSimLab is to emulate real hardware it does not have any source code editing support. For code editing and debugging the same tools used for a real board should be used with PICSimLab, such as MPLABX, Arduino IDE, or VSCode with PlatformIO. PICSimLab supports several devices (spare parts) that can be connected to the boards for simulation. Such as example LEDs and push buttons for simple outputs and inputs and some more complex ones like the ethernet shield w5500 for internet connection or the color graphic display ili9340 with touchscreen. The complete list of parts can be accessed in the documentation. Documentation at https://lcgamboa.github.io/picsimlab_docs/stable/

A retargettable micro-controller and embedded system emulator architecture, providing common supports to emulate various types of micro-processors & devices on an x86 PC. Development of emulation for Arduino and various shields is just about to be launched in 2012.

Syllable Desktop is a complete operating system that is easy to use, powerful, lightweight and extraordinarily fast and responsive. It has its own kernel, filesystem, GUI and applications. Syllable Server is a matching small and efficient Linux server.

C-BIOS is an open source BIOS for MSX computers. C-BIOS can be shipped with MSX emulators so they are usable out-of-the-box. This project aims to improve C-BIOS by fixing incompatibilities with the MSX BIOS and the development of a Disk ROM.

Haiku is an open-source operating system currently in development designed from the ground up for desktop computing.

JNode is a Java New Operating system Design Effort. JNode is a simple to use and install Java operating system for personal use on modern devices. Any java application runs on it, fast and safe. See our homepage for additional information.

BerserkArch is a security-focused, performance-tuned Linux operating system (OS) based on Arch Linux, designed for developers, hackers, and technical users. A bleeding-edge, security-centric Arch-based Linux distribution crafted for hackers, developers, and nerds alike. Following the Arch Linux philosophy, it is designed to be highly customizable, allowing users to build their environment with only the components they need, rather than having a lot of pre-installed software like some other security distributions (e.g., Kali Linux). As an Arch-based distribution, it benefits from the rolling release model, providing users with the latest software versions and kernel updates. BerserkArch is a dist "designed to make you powerful" for specific use cases like reverse-engineering binaries and automating exploits, rather than being an easy-to-use distribution for general beginners.

ZeX/OS - operating system

This project is a partial overhaul of the Arduino hardware library, i.e. the main source files that make the core library. The intent is to reduce the overhead introduced by the initial library and eliminate the numerous function calls whenever direct register access is possible.

Software Development Kit for the Nintendo(tm) Gameboy Advance(tm) based on GCC.

HALT is a developer friendly programming and simulation environment for the Motorola 680x0 family of processors. Targeted at academia, it is centered around ease of use and utility.

Hardware and firmware for a DSP based digital audio MP3 player with USB pen drive funtionality, using a 16-bit fixed point Texas Instruments TMS320 C55x DSP and CompactFlash card. This is an open source and open hardware MP3 player project.

The repository of the binaries for Windows of Parrot (Perl6 VM). The Parrot speaks your language but lives on http://www.parrot.org/

Clicker is a project for a Multitasking Open-source operating system written from scratch. based on a modular micro kernel. We want to explore new way of designing and using OSes :) [newz: PCI, NE2K and VBE]

This program emulate the Sega's System 16 arcade boards used by many Sega arcade game between 1987 & 1989 like Shinobi, Altered Beast or E-Swat. There is more than 20 existing System 16 games. The System 16 board uses a Motorola 68000 cpu at 10Mhz for the main program and a Z80 and on YM2151 for the sound. The actual version of the emulator emulate many more than the single System 16 board because now you can play with System 18 games like Shadow Dancer, with pre-System 16 games like Quartet II and even with some dual 68000 games like Hang-On and Space Harrier. This program is an emulator and it needs roms to run, please, don't e-mail be to get roms, i'll ignore your requests !

Age Of Empires revisited is a repackaging of the original game entitled Age Of Empires, developed by Ensemble Studios and Produced by Microsoft. The AOE community has made some very exciting mods, patches and changes to the game. Till now very few have made a collaborative attempt to introduce the best of those mods into one mod pack. Our aim is to use our experience as gamers to bring to you a better balanced game with added features that will truly feel like a re-release of the original game.

Program for viewing, editing, manipulating, and analyzing absorbance spectra. Simple arithnetic includes making linear combinatins of up to 10 spectra. Advanced functions include fitting spectra as LC of standard basis spectra, singular value decomposition, Fourier transform, differentiation, integration, global fitting of 3D titration and kinetic data. Graphics features allow composing Figures and export to postscript files which can be converted to pdf, imported into photoshop for rasterization, or used in page design software like Illustrator.
