PiGRRL Switch

So keeping in line with my general theme of “anything big companies do, I can do worse” I’m going to attempt to make a retro game console stylized after the Nintendo Switch.  Building a retro console is something I’ve wanted to do for a while now, but I’ve never gotten farther than a bare Raspberry Pi running RetroPie.  Making this project would give me a retro console like I’ve wanted with some of the features provided by the Nintendo Switch.  Another reason I wanted to do this project is because it’s been so long since I’ve done any high level programming or Linux development.  With OpenADR moving away from Linux, this project will be a refreshing change of pace, a chance to brush up on old skills, and an opportunity to learn more.

And luckily for me, there are a ton of great resources that I can utilize for my build.  RetroPie already has a great emulation console and interface with tons of users.  Additionally, what I’m doing will be heavily based on Adafruit‘s PiGRRL.  A lot of the design, programming, and resources are already there, I just need to remix them for what I’m trying to do.
