Setup for Tang Primer 20K

If you own a Tang Primer 20K board, you can also run NESTang. The following components are required:

  • Sipeed Tang Primer 20K board
  • Muse-Lab HDMI PMod if you got the "lite" version of Tang board. You can purchase it from aliexpress or taobao. The "dock" version of the board already has an HDMI port, so there is no need for this component. The wiring instructions for the "lite" version can be found in the doc/wiring.md file.

Follow the instructions below:

  • Download NESTang 0.4 since later versions only support Tang Nano 20K.
  • Launch the Gowin Programmer application and program either the nestang-lite.fs or nestang-dock.fs file, depending on your specific board. If your setup is correctly configured, a colorful NES palette should be displayed.
  • Connect your game controller/controllers to your PC. I use a pair of old Xbox 360 controllers.
  • Use the command loader.exe -c COM4 games\rom.nes (replace COM4 with your port number) to load the game rom.nes. If the game does not load, install Microsoft Visual C++ Redistributable package to resolve any missing DLL errors.
  • Press the left button (LB) to open the in-game OSD menu, from where you can load other games located in the games directory.
  • If the game does not load, run loader.exe -r game.nes to generate error messages from the core.

Congratulations! Now you can enjoy all your favorite NES games. For version 0.4, a Linux loader program is also available. See Linux loader for details.
