PiBoy 64

So the screen I selected from Alibaba has a 18 pin 0.8mm pitch FFC connector, which after a few days of searching and calling a few connector manufactures, is almost impossible to source in quantities under about 3000. It includes a resistive touch screen but upon examination, it looks like there is a sizable air gap between the plastic viewport and the actual screen so I don't know if the screen will be able to be used. I'll explore that in the future though. Perhaps with a little creative dremeling, it's possible. The goal is to have to do as few modifications as possible on the case itself.

So the idea of a coprocessor is that it can handle the button pressed, take over the screen during boot up (I really hate that ugly boot screen with all the text). I want to show a class nintendo screen as well as play a sound file. A simple 8-bit SPI DAC will be used to connect to the speaker. After a certain amount of time, a bus switch will be used to turn on the output of the Raspberry PI to the screen. The coprocessor is a ATMEGA32U2 which has a built in USB host, which makes it very easy to emulate a USB device.

Well the journey begins. I've never manufactured a PCB before though I've done plenty of projects on perf board which probably really could have used a PCB. The major steps before me are figuring out how to wire out ports, having adequate storage, and configuring the co-processor.
