Does anyone know how to install cavestory on retropie? It's listed on the wiki as a port (https://github.com/RetroPie/RetroPie-Setup/wiki) and i see it in the port list in retropie itself but i need to get the package to install it somehow?

The wiki links to https://github.com/RetroPie/RetroPie-Se ... /CaveStory but it's sort of ambiguous...

Do i just dump the prepatched folder into "/home/pi/RetroPie/roms/ports/CaveStory" and that's it?
