» Flat Assembler 1.67+

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 and x86-64 (both AMD64 and EM64T) instructions, 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.
IMPORTANT NOTE: FASM isn't a virus and the files from their "official" page aren't infected either. The high occurrence of *false positives* on FASM (up to 1/3 of "antivirus" products can get upset) is a known fact and has been reported many times. Do a search on Google AND your AV program's virus database for the name it reports - can't find it = false positive!

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.

» GoLink 0.21

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.

» GoRC 0.60

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.

» PORT 1.1

If you're a Palm OS programmer writing shareware, you need a way to generate registration codes from the Palm user name and perhaps some other data. PORT is the tool set I whipped up to accomplish that. They are free for use under the terms of the GNU General Public License. The one module you link with your Palm program is not GPL'd, so that you may use it in closed-source projects. I still do hope that you send bug fixes and such back to me.
