I’ve written a set of scripts (for RetroPie on the Raspberry Pi) that activate the correct nonstandard refresh rates for each game (by looking a refresh list up) that needs them on LCD monitors. LCDs go by 1 Hz increments, so for example with R-Type and Mortal Kombat the monitor runs at 55 Hz, with Neo Geo games at 59, with Double Dragon at 57 and so on.
It’s called by runcommand-onstart.sh and runcommand-onend.sh on RetroPie, and I’d love to have the same functionality with Lakka. Running the refresh rate switching commands from the command line via ssh sort of works, but there’s no hook that I can find to do it when launching and then quitting a lr- core. Any news on that front?
The only previous discussion I found is at Custom scripts system?
