I wish I was good at fighting games. I'm not.
I wish I could use a joystick. I cannot.

What I CAN do is create

I'm familiar with blue-switch keys. They're what I like and what I'm comfortable with.
If I want to get better at fighting games, specifically Ultra Street Fighter IV, I need to use a "joystick" that I'm comfortable with.

That's where this comes in. I've place Cherry MX blue switches on a custom PCB with a 3D printed enclosure (I had to learn autocad for this lol) arranged to have arrow keys on the left and action keys (vertically spaced like a Japanese fight stick) on the right.

Using the Pico to act as a USB HID device, I can send the right keyboard signals in order to use it with USFIV.
