Soon I need to design a keyboard adapter for the controller port. It's not too complicated -- I need to use three pins on an Atmega to emulate a 16-bit shift register, returning two-byte packets representing the modifier keys and next key scan code in the buffer, while also reading an actual keyboard - for simplicity, a PS/2 keyboard for now. So it will need a PS/2 port, a SNES controller cable, an ATMega with at least five GPIO pins, and a 3.3V-to-5V boost converter to power the keyboard.
Later on, I would prefer a USB keyboard adapter. Not entirely sure which MCU would be most suitable to that. RP2040 maybe? Not really my area -- would love someone to volunteer for that if it interested them.
