Lakka Pi Switchres for Tri Arcade Sync Monitor Scan Rates

Libretro Lakka
#1

I have a Pi 3B+ and would like to use Lakka to auto switch scan rates based on game ROM for my tri sync arcade monitor (15KHz, 24KHz, 31KHz)

Do I need to use Switchres to do this? I see that CRT Switchres is no more but there is now Switchres 2. Do I need an older version of Lakka?

Any input is appreciated!

I found out this is possible without Switchres using Retropie with the run command. Noting this because may be helpful to others.
