Replace the oscillator of your console to either have a proper PAL or NTSC signal or fix the vertical Refresh rate of the video.
This version is more suited for consoles that have no metal can oscillators inside. The input supply voltage is 3.3V (3.6 max). This version is suited for consoles such as the Playstation 1 or the MVS MV-1C.
It works like this:
This PCB store two frequencies, and you can switch between them with the S0 input by changing its state: High (+5v) or Low (Ground).
You can select 2 plateforms
S0 = high => 53.693175 MHz (=15x NTSC subcarrier) S1 = low => 53.203425 MHz (=12x PAL subcarrier)
