@zing said in Best arcade input:

@0zzy

me too, but with some adapter lile pi2scart i don't think there is a way to use them for controls, is it right?

Now I understand your question.
Sorry, I've never used GPIO personally, but as far as I know there are some types of GPIO expander cards, and I'm guessing you can do it yourself (but it's easier to buy) like this:

I don't know if this brand/model is good, I don't even know what all the existing models are, as I've never used it, I can't recommend a specific brand/model, but as far as I understand, those who need GPIO for 2 purposes use something like that ...

Hi @Zing thanks for your reply.
But there is something i dont have clear.

Online there are a few image about gpio pinout used for arcade controls
There are 40pins:
24 are used for controls
8 are gnd
8 not used for this purpose

Do you know which pins are used to pilot rgb and sync signals?
