Not much of an update, but started testing out electronic components. First up is the on/off. It is a simple SPDT switch connected to the adafruit 1000c. I did the same connections as Wermy on his custom GBZ build. Circuit tested out good, so i will update next time with any news.

Waiting on the Screen, ordered the GearBest screen, since it is proven to work.

Tested the V3 controller, the Pi turned ON, but got no response from button pushes. Tried connecting a keyboard to the OTG and also no response. I desoldered the components just in case the Pi was fried.
But the pi works with a keyboard connected without the V3 controller.
Will contact TinkerBoy for any suggestions.

Yay! So I contacted TinkerBoy and he suggested I tried a fresh install of retropie. I did so and the Pi immediately recognized the V3 board.
Will test with ROMs at a later date.

I am thinking of painting it, because I did the hole for the microUSB charging port and it came out so ugly. I am thinking of using plastic or epoxy putty and fixing it back up.

And this is my test rig. Everyting wired up except for L1R1. I simply jumpered the pads with a small piece of wire while setting RetroPie controller.

I am waiting on the monitor to come in and I think that would be the final piece so I can start putting it all together.

Thanks for your interest!

I received my Gearbest screen today, have been unable to test it out due to work. Tomorrow I should have an update.

I am really excited for this part of the project!

Forgot to take progress pictures, but I made a bracket for the screen with acrylic and glued it down with epoxy.
The screen is only pressure fitted. Not glued down, however it took a lot of effort to make it fit without breaking it or it being too loose.
I glued down the power cables from the power boost to the controller to route them out of the way.

Was able to test out the whole system only eith batt power and was able to play without any problems.
Now all I need is to trim cables to find a way of getting the case to close...

Forgot to take pictures of the finished interior...
Was able to finish it up and started playing it.

At the moment the battery is on the outside because I dont have the right size. I might get Helders battery when it is available.

I might have to go back in to trim some wires and make them fit better and add a speaker.
I also need to find out, why the R1 button is not being recognized by GBA games.

Managed to fix my R1 not being recognized. Still don’t know the actual cause, but i re-configured controller input and it is working.
One thing i had not noticed because I hadn’t done any kind of extended playing/testing. The Pi/powerboost seems to get very hot and it freezes gameplay after about 30-40mins of playing.

not quite sure what kind of power boost you are talking about, but maybe you can attach a heatsink on it. for me it helped a lot reducing the cpu temp of my raspberry pi cm3. talking of which, with the power of this circuit board I'm able to play yet all Playstation games I own without any freezes or stuttering. (my second build, but looking at your awesome button idea I think I have to build at least one more GB with a Playstation look.)
and for psx games you don't really need L2R2 buttons / analog sticks as this feature came 1997 as a replacement for the orig Playstation Controller:

. as far as I know the majority of psx games can be controlled without those extra buttons. at least I can use all games on my build without analog sticks.

ps.:
where you've got the Playstation replacement buttons from?

Thanks for the heads up, i have been thinking about a heatsink to see if it helps with temps and it prolongs gameplay.

From reading around the forum it seems possible to run PSx games on the PiZero but it requires some modifying of code which I don’t plan on doing... Hahaha

The buttons came from an old and “retired” PS3 Dualshock. I had to modify them to the right size since they are longer by a few mm. You can see in the pictures how i modified them.

Thanks!
