-There is a [super-project](https://github.com/libretro/libretro-super) that is designed to easily build every libretro port out there. To build every core:

 ### Building RetroArch
 ```bash
 cd retroarch
 ./configure # Script will autodetect features. Refer to --help if you want to override anything, such as --prefix.
 make
-sudo make install
