In Retroarch, go to Settings -> Path Options -> Core Directory and navigate to the appropriate folder. You can also set the libretro path using the menu. Assuming the cores are located in /usr/lib/libretro, the line in the configuration file should look like Insert the path to the libretro cores between the quotation marks on the right hand side. Look for the option libretro_directory, which may be located near the bottom of the file. Once you've located the libretro cores, it's time to open retroarch.cfg using your editor of choice. Use ls to check each one until you find the downloaded cores. If the directory does not exist, you can find where the cores were saved with the find command:įind may return several directories. You should see a list of all the cores you downloaded. You can check this by entering the command They should have been saved in the directory /usr/lib/libretro. ![]() Next you need to locate the directory in which the libretro cores are stored. Alternatively, you can use the find command: If retroarch.cfg is not found at that location, run Retroarch and choose the Save Config option - Retroarch will save a new configuration file and display its path on screen. By default, retroarch.cfg will be created in the directory $HOME/.config/retroarch, where $HOME is your home directory. ![]() Run Retroarch at least once to create a skeleton retroarch.cfg. This section applies to most distros of Linux, but the paths referenced may be Ubuntu-specific.īefore you can use the cores you've downloaded in Retroarch, you need to set the path to the libraries in retroarch.cfg, the configuration file for Retroarch. To install all (or at least most) of the cores in one go, run Synaptic, Software Center) or by visiting Launchpad. You can see all of the cores available to you either in your package manager (e.g. ![]() Replace with the name of the package the core is available in. Installing RetroArch on Linux Ubuntu based įirst, add the PPA for ppa:libretro/stable or ppa:libretro/testing for stable builds and dev builds respectively (instructions here), then type the following into a terminal: Alternatively, you can use Load Content>Select File And Detect Core to be presented with a list of cores detected based on the file extension of the content.įor more convenient ROM selection, setup your browser directory under Settings>Directory. The up-to-date bsnes core is a better choice for most users who are seeking the highest accuracy, except for those who require access to cheats and retro-achievements, for whom these older forks may be preferable.To launch a game, select the libretro core you'd like to use under Load Core, and select a ROM under Load Content>Select File. It is built from the 'accuracy' profile, which includes bsnes' more-demanding dot-based PPU (as opposed to the faster scanline-precision PPU used in the 'balanced' profile), though the only commercial game that requires this level of precision is the notorious Air Strike Patrol (A.S.P.). It also has some optimizations that do not reduce accuracy and some core options that can reduce accuracy (such as overclocking and HLE for the add-on chips used in many carts).
