Do these TFT screens I'm seeing really have a good enough response time to actually game on? I just want to make sure I'm getting the right one. This will be the first pi zero project I have ever made and want it to be a good expierence. I'll be making 3 of them and more if friends want them. 1 for me and 1 for each of my boys. I know that I can setup a portable router to allow us to play games together with to cool features of retropie.

Thanks for taking the time to answering our questions. Still waiting on your parts list to make final purchases. I have PIs already. :D

Yeah the cheap screens are pretty good! Here is one on a project of mine, good enough for a sonic speed run

....I love everything about this.

You mentioned using DS parts for the buttons; is it possible to use SNES controller parts as well, or are they too large to fit in there?

Can't wait to build one!

How about DSi buttons? They are probably way more common but I think they use tactile buttons rather than rubber pads.
DSi buttons are tact pads (foil domes) so are way slimmer but I've not really seen DSi spares sets for sale (maybe just because I haven't been looking) but lite shells/button sets seems way more abundant...

Far too large, I'm afraid. I have the models built around the DS lite buttons specifically, because I like membrane buttons (as opposed to dome tactile switches like in the DSi), and they are nice and small. :)

Curious to see how the controller board looks.

Could we use those long tact switches like in the Gameboy Zero L/R buttons instead of membrane buttons? I mean, based on a picture, it doesn't look like it will protrude in any way.

You could connect a shared ground like you did with the L/R buttons on the Gameboy Zero and solder it to your ground on your Teensy/GPIO or something, and solder the pin that you'd connect on your Teensy (Not sure what it's called exactly)

Did you cut up ds pcb's or make a custom pcb (or other...)
Either way it looks like I'm going to have a use for all the stripped pcb's from my cartridge port sales ;) thanks @wermy :thumbup: (this forum really needs a thumbsup smilie)

Actually I used a 3D-printed plate that the buttons rest on, along with some copper tape to make a sort of hand-made PCB. Not the most sophisticated, but it's cheap, easy and it works well. :)
Also 👍

Well I have a surplus of DS lite boards that can be used :ugeek:

Okay, a few questions.

1. Any way to hook up a potentiometer?
That'd be nice.

2. How did you connects the controls? I.e GPIO, Teensy

If you can answer these, that'd be great!
If not I'll just wait for the guide ;)

1. I was initially going to but space in there is, as you can imagine, pretty limited. :) You can control the volume within either retroarch or emulationstation though. I may be able to get it working so that you can use some keycombos to adjust the volume easily -- we'll see.

2. GPIO, using the Retrogame library Adafruit released: https://github.com/adafruit/Adafruit-Retrogame
