Title: GroovyArcade - Black screen / Unsupported resolution when launching game
Post by: ternary on April 21, 2020, 02:30:51 pm

I have setup the latest GroovyArcade using the generic Arcade 15Khz monitor setting. All works well, I see the splash screen and the list of games loads and displays correctly.

If I try and launch a game, have tried Robby Roto and World Rally so far, the screen goes black and I can hear my monitor (Polo2) whining like it does when it is recieveing a resolution it doesn't like.

Where am I going wrong? Do I need to setup the emulators themselves to be 15khz?

Not much relevant information such as the video card brand etc.

Try setting -dotclock_min 25.0 in mame.ini.

Thanks for the suggestion, changing that in mame.ini resolves the issue and the games work correctly.

But, I am having to adjust the horizontal frequency pot on my monitors (Polo25) remote board when the game loads. Once I adjust it everything is fine, but if I quit out to the mennu then I need to adjust it again.

Anyone any suggestions on how to resolve this new issue?
