The Behar Bros’ have just announced the “RGB16”: An RGB SCART output board for Neo Geo MVS motherboards. This board will allow you to solder to the JAMMA outputs of an MVS board and get both audio and video through a SCART socket: https://www.beharbros.com/rgb16
This device was designed as a companion to people also purchasing their upcoming VGA solution, or complete MVS package who want both outputs.
There seems to be more MVS solutions being released each month and I’m curious to see what people come up with next!
