How are you displaying the game? Is it going to a modern LCD display from HDMI, is it a CRT through a Direct Video adapter, or is it to a CRT through the Analog I/O board? In your MiSTer.ini, what is your vsync_adjust setting?

The core Frogger uses is the Scramble core --> https://github.com/MiSTer-devel/Arcade-Scramble_MiSTer - These are the games currently implemented for that core.

Amidar
Anteater
Armored Car
Battle of Atlantis
Calipso
Dark Planet
Frogger
Lost Tomb
Mars
Mighty Monkey
Minefield
Moonwar
Rescue
Scramble
Speed Coin
Strategy X
Super Cobra
Tazz-Mania
The End
Turtles

Thank you for the list with the other games that share the same core.. I will test.
My setting in vsync_adjust=2
Best!

Can you explain me how to do it?

video_mode=9
video_mode_ntsc=9
video_mode_pal=9
refresh_min=30
refresh_max=50

vsync_adjust=2

Sure thing! For my video modes I specify 50hz modes, forcing the NTSC mode to match the PAL mode. This probably doesn't do much but setting refresh_max to 50 should do it:

Code: Select all

video_mode=9
video_mode_ntsc=9
video_mode_pal=9
refresh_min=30
refresh_max=50

This not only fixes frogger but also fixes a lot of random issues I have in the GBA core when I enable rewind state as well!

Also I have vsync_adjust set to 2

Code: Select all

vsync_adjust=2
