Important Message

COVID-19: Mod kits to UK addresses can be posted with a second class large letter stamp via a post box so there is no restrictions or delays for me to post these. Install services and international orders need to be taken to the post office and might be affected by movement restrictions in the UK and potentially have three weeks of delay from 23rd March 2020. I am really not sure. Thanks

Sega Master System Switchless Region Mod Kit

Sega Master System Switchless Region Mod Kit

Stock: 4

This kit includes;

  • 1 x Custom Master System Mod-board (Switchless Region)

  • 50Hz / 60Hz video rate switching for full screen, full speed gaming

Product Tabbed Info


When the Master System Switchless Region Mod is correctly installed the console will be able to run games in their correct aspect ratio and speed.

The reset button is used to cycle through the video refresh rates.

  • Setting 1 = Green LED – 60Hz
  • Setting 2 = Red LED – 50Hz

If you are running your PAL systems in 50Hz, you are really doing the games a great disservice. I consider these switchless mods necessary for PAL consoles.
