I had a major head scratching moment with the same thing. Try manually typing the code within the /etc/udev/rules.d/10-retrogame.rules file, i had issues with copy and paste actually putting the wrong characters in. It was the double quotes that got me, they looked like double quotes, but when i typ...

wow 0.4mm pcb!!! thats crazy!! i guess the next step down is flex, which will save a fraction.

trimming a few mm might not be too difficult. but i would have to re-design the case again

ah ok, you wont be moving those pins anytime soon

This is a cool little project and I'm going to try to make one. I just used the quote so you can see I replied. First off, thanks for the kind words, it's always good to hear. I think I have exhausted all the ways to make this smaller. The pcb is already 0.8mm thick and the pi is soldered directly ...

your pictures done appear to be working

plot twist!!! you dont need to boost to 5v!!! the pi will happily run down to 3v, and the screen will be happy with it too!! the numbers on the battery relate to the size. im guessing it will be 8.5mm x 17mm x 30mm, 400mah should get you just over an hour with no boosting, maybe just under an hour i...

What screen are you using? If you using fbtft to drive an SPI screen, you can manually adjust the DC and reset pins for the screen connection

Awesome work

I have helped a few people (even though this is like my direct competition) you could start with the TinyPi image http://files.pi0cket.com/TinyPi/OS_image/TinyPi-Retropie-v4.3.zip then change /etc/modprobe.d/fbtft.conf to adjust the reset and dc pins, while adding the led pin number too then change ...

by jingo, thats next level stuff!!! amazing
