@paradadf to play correctly a PAL rom two things are needed

• the EMU must recognize the PAL rom and runs it at 50fps (no problem on that)

AND

• the video mode output must be at 50Hz (720p@50Hz, 1080p@50Hz or similiar, the resolution doesn't matter)

By default EmulationStation and the emu run at 60Hz, and so I set a different video mode for the snes emulator in recalbox.conf, to have a 50Hz video output when I use a SNES game.

This setting doesn't work properly and so I get the emulator running (correctly) at 50fps and a 60Hz video output, resulting in a stuttering image.

@paradadf all my SNES roms are PAL, and the emulator correctly detects and runs them at 50fps (easily verified by the "show framerate" option).

On the previous recalbox 6 on Rpi3b + the snes.videomode setting worked perfectly, even to switch from 60Hz (EmuliationStation) to 50Hz (SNES emu)

This is why I talked about a possible bug, because before everything worked fine and now it doesn't.

Hi,
first of all many compliments for the wonderful job you are doing

I just signed up and wanted to contribute by reporting an annoying bug I found on my Rpi4.

I have all my SNES roms in PAL format and so I want to set a 50Hz video mode to have a smooth image.

So I set "snes.videomode = CEA 31 HDMI" in my recalbox.conf (CEA 31 = 1080p 50Hz)

However, I noticed that the SNES emulator still ran at 1080p 60Hz, the same mode as the Emulation Station interface.

So, to check if the snes.videomode line was completely ignored, I set it with CEA 19 HDMI (= 720p 50Hz).
By doing this, the SNES emulator worked ok at 720p, but at 60Hz!

Also tried to put "global.videomode = CEA 31 HDMI", nothing

As a last test, I put 50Hz on the ES interface "system.es.videomode = CEA 31 HDMI" and at this point my SNES emulator also started at 50Hz.

So I think there is a bug, at least in this configuration (Rpi4 - Snes emu) that prevents you from changing the emulator refresh rate.
