Dual Frequency Oscillator (DFO) + Switchless mod for Sega Genesis/Megadrive

This is PCB wich replace the Main Oscillator on the Sega Genesis/Megadrive model 1 and 2.

This was not tested on Model 3


This mod regroup on a same design:

  • The Dual Frequency Oscillator (DFO) with frequencies for both PAL and NTSC
  • The Switchless mod (with DForce3000 code) which cycles between USA/JAP/EU region for video signal and language settings and RGB led support.


The kit contains:

  • A PCB already programmed with Sega Genesis/Megadrive frequency (you don't need the programmer)
  • A PCB for the RGB LED  (they will be populated with proper components, pics are here as exemple). You need to select the model of your console.



Here's a video of my installation on my own console.
