Well, the SCART socket has a composite in pin. You could connect Pi composite out to TV composite in (and ground) and be done.For RGB SCART you can probably leverage the VGA666 design and deliver VGA...

I’ve tried powering a Pi 4 from LiPo before — you’ll want at least a 3A boost converter at 5V, especially if you’re running a screen or doing emulation.Modules like PowerBoost 1000C work well, or a...

I'd use a Pi4 for that. It's a much easier platform power wise. Nothing that can't be overcome on a Pi5, but there's loads of threads on here of people with problems.Maybe if it needs to be Raspberry,...
