Uhhh I’m not sure, this case is a kit that comes with everything but the pi, batteries, and sd card.

As far as software, I just roll a retropie image that I customize with Gameboy splash screens, etc.

I’m more experienced building retropies into a Nintendo cartridge. I used to make a ton of them during the pandemic. I eventually made my own retropie image that was all set up for mass producing.
