VGA666 SLG for Raspberry 3/Retropie config

樹莓派with Retropie Peripherals應用設定
A memo for Raspberry/Retropie with VGA666 SLG made by RgR Martin (Chris)
It is a Raspberry Pi 3B peripheral made for generating CRT scanline via GPIO. The major purpose is to decrease the loading of SoC when using emulators with scanline shader. Such method can effectively produce retro feelings and also smoothly run the games.
▼Below shows the combination with RP3
▼The original output function can still be retained as the SLG is hooked up.
You have to make some adjustments in the config.txt to activate the output function of the SLG. Following are the settings and procedures.
