Not Smooth Scrolling and the music is too fast in 50 hz "Pal"

birdybro commented 1 year ago

Do you happen to have a recording from original hardware (a PAL SMS and not a PAL-modded SMS) for the video or sound to compare?

As for the smooth scrolling, what is your vsync_adjust= setting set to in your MiSTer.ini if you are using the scaler (either to a 31khz CRT or to an HDMI display)? If the scrolling is on a PAL CRT with 15kHz signals, I'm curious what could be causing scrolling being not smooth when compared to original hardware.

Thanks to your comments, I found where the problem came from. I play on a CRT 31hz IIHAMA, so that everything is perfect in PAL 50hz "scrolling and sound" you have to be with vga_scaler=0.

I tested on CRT 15hz, scrolling and sound are perfect, I have no difference with my Master System PAL console. Thanks for your help.
