As the owner of https://RetroGame.Club I am very excited to hear of a prospect of a blockchain powered arcade with high score rewards on the blockchain, that would be AWESOME. If only we could obtain the rights to use official roms, or buy the commercial license for a pandora's box type of setup or something, that would be so awesome to compete for high scores online on the blockchain.

My mind always goes straight to "how can we get this on RaspberryPi" haha since it's such a ubiquitous hardware board in the retro gaming community. Below are some of my Raspberry Pi consoles. Powered by RetroEvolved, a customized and pre-configured distribution of RetroPie with arcade bezels, shaders and more preinstalled.

I dabble in visual novel game development but I could never have the patience to design an arcade game so props to you guys!
