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

Switchless Region Mod

The Master System Switchless Region Mod lets you change the video rate between 50Hz and 60Hz which means you will be able to play games in their correct aspect ratio and speed.

The reset button is used to cycle through the regions.

  • 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.

Note that this mod will require using the console's native RGB output via an RGB SCART cable. 60Hz regions will be black and white via composite output. RGB is recommended over all other video outputs because of its superior video quality.
