SNEeSe is an emulator for the Nintendo SNES console for x86 PCs. SNEeSe is written in 32-bit C, C++, and NASM x86 assembly. Project goal is to make as accurate, functional, and usable an emulation core as is reasonably possible.
Vavoom is Doom/Heretic/Hexen/Strife source port. It features software, OpenGL and Direct3D rendering, VavoomC scripting language, slopes, 3D-floors, Quake style lighting engine, pure client/server architecture with in-game joining and a lots more.
The goal of the project is now to develop a user library called libpfm4 to help setup performance events for use with the perf_events Linux kernel interface. The development of the perfmon kernel subsystem, libpfm and pfmon has now stopped.

A real Win32 extensible passive debugger
This project born a few years ago when I encountered a fatal bug on a production environment, unfortunately not replicable on my development machine. I spent many time finding a solution, using also freeware and commercial third-party tools and libraries, but none helped me because the bug crashed the process, and no of the above tools could be able to catch the exception before the process dying. Also, it was not possible to install a development environment onto the production machines, so the only solution was to develop a debugger which didn't need any user/developer interaction. I used many open source resources, then I decided to make the Bug Finder an open source project. It is built over a pluggable architecture to support other languages different from Borland Delphi (the one I used to develop my faulting application and the Bug Finder too). Here is the article http://www.codeproject.com/Articles/602794/Bug-Finder-a-real-Win32-extensible-passive-debugge .
MaxUAE is the Mac OS X version of UAE.
Transfer programs from PC to 8-bit Atari using just a data recorder
TURGEN SYSTEM is a versatile utility that allows you to create your own tapes with software for Atari 8-bit computers and transfer data from your PC or Mac to your Atari 8-bit computer using just a data recorder and a cassette adapter. Turgen System also offers extra functions for everyone who still use data recorders. These functions include turbo decoder, tape image extractor, and batch processing. Turgen System also provides a set of binary loaders for simple transfer of binary files. Suppored Turbo Systems include Turbo 2000, Turbo 2000 - kilobyte blocks, Super Turbo, B-TAPE (and compatible TURBO TAPE), KSO Turbo 2000, Turbo Blizzard, Turbo ROM, Atari Super Turbo, Unerring Master, Hard Turbo, Lower Silesian Turbo 2000, Rambit Turbo Tape (UK), Turbo 6000 (GDR), Omicron Turbo.
PlayStation 2 emulator for Windows and Linux
PCSX2 is a PlayStation 2 emulator for Windows and Linux, started by the same team that brought you PCSX (a Sony PlayStation 1 emulator). Currently, it can emulate thousands of games at full speed
Softx86 is a library that provides software emulation of an Intel 80x86 CPU. The library takes care of executing opcodes and handling exceptions while the host application is responsible for providing simulated RAM, I/O devices, external signals.

NewWolf is a conversion of a famous 3D action game: Wolf3D by ID software. The purpose of this project is to make a stable, extencible and portable 32bit version of Wolf engine. To allow users run it in different resolutions and on various platforms.
scmRTOS is tiny Real-Time Preemptive Operating System intended for use with Single-Chip Microcontrollers. scmRTOS is capable to run on small uCs with as little amount of RAM as 512 bytes. The RTOS is written on C++ and supports various platforms.
This software boots your PC and analyse your filesystems. It displays a graphical menu for you to select which system to boot. Intended to replace LILO and Loadlin, written in C with GCC, fully real mode.
lmesh is a 3D render implemented local illumination such as Gouraud and Phong. Currently it is written by C++ and does not depend on the GPU instructions or any exsiting 3D libraries. It plans to achieve more realistic effects in the future
Haiku is an open-source operating system currently in development designed from the ground up for desktop computing.
Advanced FrameServer is plugin for Adobe Premiere CS5.x, based on DebugMode FrameServer (www.debugmode.com), fully rewritten and optimized for 64-bit platform.
Gameboy and Gameboy Color emulator for Android phones
This project is based on sources published by original GBCoid developer, who in turn used code of gnuboy. Help and suggestions are welcome. This project has been abandoned in favor of RetroArch, another awesome free software console emulator (which is also actively developed): http://www.libretro.com/.
BASIC Compiler and Interpreter
John's Mutant contains several projects. The current project is a Minimal BASIC compiler for Linux systems using AMD64 compatible CPUs. You can download the MinimalBASIC compiler source in the Files section.
Fast and efficient self-assembling 80x86 assembler for DOS/Win32/Linux; with 8086-80486/Pentium/MMX/SSE/AVX/XOP instructions support, 16-bit/32-bit/64-bit code, binary/MZ/PE/COFF/ELF output formats.
The netboot project allows booting a diskless PC over a TCP/IP based network using standard protocols like BOOTP, DHCP and TFTP. It is able to boot Linux, FreeBSD, multiple DOS variants (including MS-DOS, PC-DOS, PTS-DOS, OpenDOS, NovellDOS, FreeDOS)
Yoda's Protector is a free, open source, Windows 32-bit software protector.
Our mission is to explore and develop new operating system concepts; to redefine the architecture while using assembly language for most of the underlying architecture.
Microcontroller based PC Oscilloscope
PPMScope is a do-it-yourself oscilloscope with an open source design. The intent is that the project can be constructed by an electronics hobbiest using the instructions included. The design is a compromise between features and cost. The bandwidth is lower than a commercial scope, so it's use is limited to signals of 500 kHz and below. It's sample buffer is also smaller than a commercial scope, however sufficient for most oscilloscope functions. This is a version based on the PIC16F877A microcontroller running with a 20MHz clock. The maximum sampling rate is 1 MHz with a 5 Mhz equivalent sampling mode. Currently, the computer interface supports USB, serial, and parallel ports. Good luck on the construction and I hope you enjoy your oscilloscope. I am happy to answer any questions or provide technical support for this design.
