Growing up this bad boy was my family’s only gaming console: It had Ms Pacman, Galaga, Mappy, Pole Position, Xevious… that might have been it? It was like you said, you just plug it into the video and audio jacks, it was all one thing.

its not on the same board,
but you could build something like that with a gp-2040 board and a raspberry pi running RetroPie

not sure if fightcade runs well on the raspberry pi’s arm chip tho (since you called it a fightstick instead of arcade stick)

You’re not gonna believe this
