@mitu said in How to setup my game into raspberry pi?:

the Emulators shipped in RetroPie support JavaScript based games (if your game is programmed in JavaScript), you'd need a browser to run it. RetroPie does not ship with a browser, but you can add it by install

i see, cause this project im working on now required to be play on web browser(thus the .js format) and also on an arcade machine(where my problem come in, the installation on raspberry pi)

So this mean my developer will need to code in perhaps in a coding language that can both run on web and in retropie ?
