This is an unscrewable SNES plug - these are designed to fit a sync stripper (for pal GameCube and others if required). We also had the idea to try a 90 degree angled version, as shown. Both versions will be available. The 90 degree angled one will fit in a base SNES, SNES mini and Famicom Jr/Av NES. An N64 version of the 90 degree angled plug will have to be specialized, this basic one won't fit, the plug will have to be elongated.
We are now working on the adaptor port for SCART to 34 pin RGB Sony CRTs.
