@elfi I know a lot of folks in the retro scene. Tell me about your idea.

@mos_8502 It's not a whole lot, admittedly. I mostly just looked into it since the lack of composite AV felt like such an oversight with the RPi400. It'd be using an RGB444 DPI configuration from the GPIOs with the ADV7393 chip to produce CVBS and Y/C signals to output over RCA, and optionally include PWM or I2C-driven audio. Alternatively, a 7341/7343 would allow RGB666

It does come up a bit more expensive to make than getting one of those cheap mini HDMI2AV adapters, and the cheaper chip would have a lower colour depth (though entirely within the OCS's range), but it should have a much faster response time by comparison and would snugly fit against the GPIO port. Dunno if there's much interest in that or if something already exists, I couldn't find anything looking around anyway

@mos_8502 If I ever got bored, I could probably use an I2C GPIO chip to add DE-9 joystick ports too, possibly with dip switches to toggle between Amiga/CD32 and Megadrive compatibility

@elfi Sounds like a great idea.

@mos_8502 Think it'd be worth pursuing prototyping and maybe production then?

@elfi It's definitely worth building yourself a prototype on a breadboard and testing the latency. The retro gaming / CRT folks are eternally after getting hold of a lower latency.
