Okay I also needed my trusty old Pelikan PS2 PS3 adapter but it works! I can play NeoGeo with my old PS2 Tekken arcade joystick. It also works with my PS3 controller and Xbox One Blue Tooth wireless connection. But a few other adapters didn't work, including some from Mayflash. It works with Mayflash MF001 but not with MF104, PC044 or PC053. Maybe add compatibility later.
