Lakka 3.0 includes the latest version of RetroArch

Lakka 3.0 includes the latest version of RetroArch, which is currently 1.9.3, updates to all supported kernels, plus new kernels added. We recommend that you do a "clean" installation to avoid any incompatibility issues, as significant changes have been made to the underlying operating system and RetroArch. The boot partition size has been increased to 2 GB, which is not compatible with previous installations.
