The flat assembler is a fast and efficient self-assembling 80x86 assembler for DOS, Windows and Linux operating systems. Currently it supports all 8086-80486/Pentium instructions with MMX, SSE, SSE2, SSE3 and 3DNow! extensions, can produce output in binary, MZ, PE, COFF or ELF format. It includes the powerful but easy to use macroinstruction support and does multiple passes to optimize the instruction codes for size. The flat assembler is self-compilable and the full source code is included.

Toolbar paint is a paint package that is specifically targeted at developers who wish to design their own toolbar button graphics. It can open toolbar bitmaps with up to 64 buttons and allows you to visually design a toolbar using a wide selection of editing tools. It also includes image manipulation tools to replace colors, apply gradients and more. The toolbar graphics can be saved as 16 color, 256 color, 24 bit or 32 bit bitmaps to incorporate in your application. A tiny and powerful editor, written entirely in assembler. Additional plug-ins are available from the website that let you save a button as an icon file, add additional effects, save the enitre toolbar to an animated icon and more.

This is a fast resource compiler which can make a RES file for linking from your RC files, and/or can make a COFF object file. One of its advantages is that since it knows all the constants you can do away with header files! It is one of the "Go" development tools.

GoBug Symbolic debugger for Windows programmers with special features for analysing code, data, events and messages. Disassembly is in assembler, comes with comprehensive help file and demo program. This free version works on 95, 98, and ME (NT, 2K and XP version is available for purchase). This is one of the "Go" tools.

This is a fast free linker which takes COFF object files and a RES file and makes Windows exe or dll files, with or without debug information. One of its advantages is that it has no need for Lib files - looking instead at the Dlls themselves! It also has an easy to use loader for the Microsoft Layer for Unicode. Used with GoAsm it can report on redundant areas of code and data. It is one of the "Go" development tools.

Win32+assembler is becoming more and more popular, you can use a low level language (assembler) together with a very high level language (the Windows API) - a perfect combination! GoAsm is a fast, free, assembler for producing Win32 files. It has a particularly clean syntax with a number of optimisations for Win32 and a comprehensive help file which contains sample code. It is one of the "Go" development tools. If you are interested in 32-bit programming for Windows 95/98/ME or NT/2000/XP using assembler, you will find everything you need here including an Editor, Assembler, Resource Compiler, Linker, Symbolic Debugger, Help Compiler, Information, Sample code and demos and Links.

PEDasm is a Win32 command line tool which disassemble binary files targeted for win32 X86 platforms. It produces on output an asm source file that can in several case be successfully recompiled with masm.

This Win32 disassembler for .exe and .dll files. The program works in console mode and uses the command line option: disassem yourfile.exe > yourfile.txt

A DOS-based command-line MC68HC11 cross-assembler that can generate source-level MAP files, S19, LST, ERR, and (EM11 or Shadow11-compatible) SYM files. Assembles many files in one command. Supports upto 100 (nested) INCLUDE files. Full path error reporting for smart IDEs. Includes extra instructions (built-in macros), and several assembler directives for controlling listing, source-level mapping, tabs, case sensitivity, extra instructions, segments, etc. Automatic use of Direct Mode without possibility of phasing errors. Supports conditional assembly with user messages/errors/warnings. Up to 10 assembly-time symbol value assignments. Local labels within each main/included file. Not crippled in any way.
