Note that I do not take any responsibility to any damage caused to your system, controller, or pet dog with this software. I have tried to make sure that it will work flawlessly on as many machines as possible, but can make no guarantees. Email me here if you have any problems.
Windows 2000 currently requires only a registry file to get it fully working. This can be downloaded below. Once it's downloaded, import it into your registry by double clicking on it, and then there'll be 3 extra game controllers in the Gaming Options control panel. (One each for 2, 3 and 4 Axis controllers)
Windows 98 currently requires a registry file and a driver file from CH Products. I have included this and instructions for installing them in the zip file below. Download and unzip to a directory of your choice, import the registry file by double clicking on it, and then place the CHjoy.vxd file in your Windows\System directory.
