Serial PFC HWC3 Simulators

This page is for serial Hardware Controller 3 (HWC3) devices. If you have a USB device, go back to the main page and look for your simulator. If you're not sure, check this page. (Note that the USB and serial versions use identical hardware, the difference is in the firmware.)

  • Hex File Utility Put this executable somewhere in your path, or in the same directory as the batch file.
  • HWC3_Upgrade Here's how to upgrade to the latest USB code. (Note: Serial instructions coming soon. These instructions can be used with these changes: you do not need the jumper; plug the USB cable in before you apply power.)

Please contact technical support before using these files. Please contact sales or support if you would like to upgrade to USB.
Right-click and select "Save Target As" (Internet Explorer) or "Save Link As" (FireFox) to download the Hex file. Otherwise your browser will probably just display the raw contents. Your browser may try to save it as a text file. More later.

* If you're programming a ROM directly in a ROM burner, you'll need the version of the hex file that includes a bootloader. See the output file directory for the appropriate file.
