S1 = low => 53.203425 MHz (=12x PAL subcarrier)


  • Neo Geo MVS (Output Correction):

S0 = high => 24 MHz (Vertical Refresh Rate = 59.94Hz) 
S1 = low => 24.305909760 MHz (
Vertical Refresh Rate = 59.1856Hz // Original Frequence)


  • Saturn:

S0 = high => 14.31818 MHz (=4x NTSC subcarrier)
S1 = low => 17.734475 MHz (=4x PAL subcarrier)


  • Staturn (correction):
S0 = high => 14.31818 MHz (=4x NTSC subcarrier)
S1 = low => 14.22148... MHz
