While this is a neat project, the design is very strange. Most of the complexity seems to be a result of using the wrong components for the job.

Having a huge PCB for an SD card is completely unnecessary. Also using enig for mechanically stressed contacts seems to come from a wrong understanding of why one would use enig. enig is for corrosion resistance, not mechanical resistance.

Just use an rfid tag to read out the cartridge put into the console
