Frogger screen flickering new problem

Unread post by jalbarracin »

Hi, today I started frogger and it constantly shows an intermitent black screen, like it is trying to re-sync de video screen. I always play this game so this has to happen in the latest update. I am updating with the "update all tool". Does anybody have the same issue? hope this can be fixed. Best! :ugeek:

Just tested, I'm not seeing this issue on my LCD or on my Magewell Capture card. I have vsync_adjust=0 though.

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

I've run into this and solved it (kind of) by forcing the refresh rate to 50hz.

Yup, vsync_adjust=2 is the least compatible video mode. Try vsync_adjust=1 and if that doesn't work then try vsync_adjust=0.

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
