I used to have an old wii set up as an emulator a long time ago, and having recently wanted to get back into emulating, I purchased an nvidia shield due to all the things I’ve heard about it. I haven’t messed much with it yet, but have seen some videos of people’s setup. From what I understand, retroarch is basically the main interface for emulation on the shield. Recently, I learned about which is an interface to retroarch, so interface to an interface? Either way, it looks cool. Is the only graphical interface out there? Or are there plenty of other interfaces available?
