The world’s first encoder switcher mod kit for the Sega Master System. Finally it is possible to have a real multi-region Master System with correct colour encoding in both PAL/50Hz and NTSC/60Hz modes. Designed for those that enjoy gaming via composite video. Requires a PAL and NTSC compatible TV or upscaler as this mod creates real PAL and real NTSC to match the region of the console.
Primarily aimed at PAL Sega Master System 2 consoles with the SEGA 315-5237 IO Controller IC. Other revisions will need looking at and testing before confirmation of compatibility.
Compatible with the following Sega Master System consoles.
- Model 2 / PAL / 171-6395A
- Model 2 / PAL / 171-5922A
More will be tested soon.
I am not sure how the same mod can work in an NTSC SMS console that only has a 10.7MHz crystal. There is no available PAL subcarrier frequency to make it a dual format system. More research needed.
