Setup Questions

If THEC64 Mini is not working as expected when you first setup, there are a number of things to try:

  1. Ensure that the power supply you are using is sufficient for the device. This needs to be 5V/1A for the items supplied in THEC64 Mini box. When attaching any additional USB devices, a 1.5A or 2A power supply is recommended, as other USB devices may have different power requirements. If THEC64 Mini is under-powered then it is likely to not operate correctly or behave erratically
  2. Check that you are using the latest firmware. Visit and follow the instructions
  3. Test THEC64 Mini by ensuring that it is connected directly to your TV or Monitor using the provided HDMI lead and is not using any other cables or devices inbetween
  4. If you are using a USB hub, we recommend a powered hub. Also see point 1
  5. If there is a time delay between performing an action on the joystick and seeing it on the screen, your TV is likely to be applying image processing which can cause a noticeable delay. Switch off all image processing options by consulting your TV manual. Some TVs include a special ‘Game Mode’ that you can also try
  6. If your joystick is not working correctly, try connecting it to a desktop computer and testing it there. The USB joystick will work on Windows, Mac and Linux
  7. You can test the USB ports by connecting a different USB game pad or controller
  8. If your USB memory stick isn’t detected, then ensure it is formatted to FAT32. Some people have found that formatting to FAT32 on Windows works better than if the stick is formatted on a Mac
  9. For D64 files to work from a USB memory stick, they must be named THEC64-drive8.d64. If you are naming the file using Windows, ensure you can see file extensions otherwise your file might be accidentally named THEC64-drive8.d64.d64 instead.
  10. If your TV is playing the sound but not displaying the picture, then it is likely to be unable to display the 50Hz signal from THEC64 Mini. Try a different TV or monitor
