UltraPIF timings question

Open ConsoleRefresh opened this issue 2 years ago • 4 comments

Hi Jago85.

This is not an issue but a Quick Question. Does a Pal console with UltraPIF play NTSC games at exactly the correct speed? Or are there any slight discrepancies vs an actual NTSC console?

thanks for replying if you can.

thank Nick

Hi Nick,

the video clock is adjusted as close as possible using the integrated clock generator circuit. I cannot measure how accurate it really is, but it should be very close. OSSC displays 60 Hz, while playing NTSC games on an unmodified PAL console would display 61 Hz.

Regards, Jan
