This is wizardry. For the triggers maybe you could have a hall sensor and a tact switch at the end of the travel. I think that’s how DualShock controllers do it.
Sorry for lack of updates. It’s because there hasn’t been any progress sadly. I’ve been away for a while but I’ll be home tomorrow and my parts are all here (I think). More to come!!
Le soft clickies are great. I’m l glad you switched from NTSC because it’s not great. Loving the build so far! What resolution is your display and where are the actual trigger switches?

This data sheet lays out how to get stereo audio out of 2 PWM signals on pages 23 and 24. It is the same filter used on larger Pis with native audio. It goes in to a bit more detail and it could be useful. I’m sorry that I am cluttering the forums and I will try...
I was replying to Retro95s post where he said he was trying to get analog audio out and I said I think you just use PWM. As far as I know, PWM with a filter is as close to analog audio as you can get directly from a Pi.

you can probably get both elsewhere for cheaper or make your own and combine them but just some suggestions
