Mahjong -> Jamma adapters (Interest check)

Mahjong PCBs have a real weird pinout which looks basically nothing like Jamma. Voltage pins, video, audio and controls are all different, see: https://forum.arcadeotaku.com/vi... I'm currently using a hacked together adapter that looks... not great, and want to replace it with something nicer, so I threw together a PCB design for it that I'll have printed some time soon-ish once I've double checked it, and figured out if I want to change something. Would there be any interest from anyone else in getting some of these? Would be pretty cheap since there's not really any components other than a JST header. Dunno how many people are into Mahjong though.
