Aasm is an advanced modular assembler designed to support several target architectures. It has been designed to be easily extended. Its global architecture takes advantages of dynamic libraries to provide input, assembler and output modules. The input module supports Intel syntax (like nasm, tasm, masm, etc.). The x86 assembler module supports all opcodes up to P6 including MMX, SSE and 3DNow! extensions. F-CPU and SPARC assembler modules are under development. Several output modules are available for ELF, COFF, IntelHex, and raw binary formats. Advanced features include symbol scopes, an expressions engine, big integer support, macro capability, and numerous and accurate warning messages (over 300).
Flat Assembler is a fast and efficient self-assembling 80x86 assembler. It supports x86 and x86-64 instruction sets with MMX, 3DNow!, SSE up to SSE4, AVX, AVX2, and XOP extensions. It can produce output in binary, MZ, PE, COFF, or ELF format. It includes powerful but easy-to-use macroinstruction support and does multiple passes to optimize the instruction codes for size. It is written entirely in assembly language.
Game Launcher is a cross platform, universal front end for emulators. The main goal is to provide a user interface that is easy to use and attractive, yet does not look like a traditional user interface with windows and such. Game Launcher should work with any emulator, but it has been known to work with MAME, Nesticle, RockNES, zSNES, snes9x, Callus, Stella, z26, and Versions are available for Unix, DOS, and Windows.
John the Ripper is a fast password cracker, currently available for many flavors of Unix, Windows, DOS, BeOS, and OpenVMS. Its primary purpose is to detect weak Unix passwords. It supports several crypt(3) password hash types commonly found on Unix systems, as well as Windows LM hashes. On top of this, lots of other hashes and ciphers are added in the community-enhanced version (-jumbo), and some are added in John the Ripper Pro.
Necromancer's Dos Navigator is a "Norton Commander" clone. It uses a well known text-mode interface, is highly customizable, and has a lot of features. Its key features are a text editor with syntax highlighting, horizontal/vertical blocks, multiple codepages, undo/redo, bookmarks, powerful searching, and regex; a file viewer with text view, asm/dump/hex edit, raw blocks, header viewer, search, regex, and unlimited filesize; a powerful filepanel with higlighting, VFSs, and filefind with textsearch and regex; a calculator; and more.
PopAsm is an assembler (an assembly language compiler) designed to support the syntaxes of TASM/MASM and NASM, gathering together the best features of each of them. It is intended that it will support all instructions from Intel compatible CPUs, including MMX, 3DNow!, and SSE extensions.
Yasm is a complete rewrite of the NASM assembler. It currently supports the x86 and AMD64 instruction sets, accepts NASM and GAS assembler syntaxes, outputs binary, ELF32, ELF64, COFF, Mach-O (32 and 64), RDOFF2, Win32, and Win64 object formats, and generates source debugging information in STABS, DWARF 2, and CodeView 8 formats.
