Credit card sized game console

I've developed a game console based on the ATTiny85, circuit inspiration from https://github.com/phoenixbozo. Tailoring the circuit diagram to my needs, I've designed a unique credit card-sized PCB on EasyEDA. Games compatible with the ATTiny85, available at https://github.com/cheungbx/gametiny, more than 10retro games are available.Before designing the PCB board, I prototype the circuit on a breadboard to ensure its functionality. I found that the resistance values from Phoenixbozo's design didn't match, so I substituted them with resistors I had available.
