I must say I’m kind of baffled after reading about the different vertical refresh between modded PAL and NTSC systems, particularly the Playstation, here:
Dual Frequency Oscillator
Always thought that a 60-Hz-modded PAL PS behaved exactly the same as an originally 60-Hz system when running the same game, but if I understand correctly, an NTSC PS outputs video at 59.94 Hz whilst a modded PAL PS does around 59.20. Is this right, no matter the modchip used!? And is it always like this, even with the PS One model (this poster is saying the PS One should be OK?)?
What about other systems, such as the PAL PS2 or the SNES?
