I may have misunderstood some of the translation. I mixed the files and this worked for me.

#On raspberry pi, PWMs cannot be used simultaneously with Jack sound output.
#If your are using HDMI or a Audio hat you can use backlight PWM control for the second screen
#If you are using Jack output please leave commented.

# system.secondminitft.usemarquee variabla allows you to display a different

# - /recalbox/share/roms/neogeo/media/marquees/alpham2.png
# - /recalbox/share/roms/neogeo/media/images/alpham2.png
# if set to 1, in game the marquee images will be displayed

#system.secondminitft.sleepenabled allows you to enable/disable
