Yeah, sure. A few big things were: My case was a little smaller and weirder and... square(r) than the normal case, my arduino broke after being wired to everything and everything wired to it, My pi 3 USBs never worked, and neither did the audio USB or PWM. I don't regret this build, because it taugh...

I'd forgo the teensy for simplicity, and just do a single pushbutton through GPIO. I used this guide, it was very clear and it worked flawlessly:

Hope it goes well!

Hey, I'm stopping this build for a while. Not sure if it's indefinite or not, but I made some choices with this build I wouldn't make again, and if I resume this build I'll definitely make some big changes. Thanks for reading.

Thanks! Looking forward to how this turns out.

That looks really impressive! Do you have stl files so people could print their own?

Hey, it's sad but I'm no longer taking orders. I might start again someday but I'm just to busy now and I don't want my hobby to just become more work. I am currently working on a build, and of course I'll still finish it, but I'm taking no new orders right now.

Here's my last build, I did it for a man named Vespertillio. No screen protector, because this build he supplied parts and I just put them together. Went for a 6-button L1R1 build using Kite's SAIO. I added a neat feature where you can flip a switch and the GBZ will switch from running off the lipo ...

I know a lot of people browsing the forum love seeing all the GBZs/GB3s, but can't build them themselves due to not having good enough tools or not enough experience, and don't want to invest time/money into making a GB when they just want a GB. Now I am ALL FOR people taking up this incredible hobb...

Hey,
I would try
-Making sure you have the right number of analog sticks
-making sure you're using the right version of arduino
-making sure your wiring on the psp joystick is right
Hope this helps!
