===Mednafen PSX=== Systems like the PSX require you to load games through CUE sheets. Ensure that the CUE sheet is properly set up with a relative (not absolute) paths. See the [[Cue sheet (.cue)]] for more. Mednafen is very picky about which bios BIOS to use. Choosing certain bios works better than others. The ones to use that you might need are:
===Dual analog controllers===*Delete them.
PS1 games also often used a set of default remappings if they didn't support it directly. Some games used both analogs as *Rename the dpad, RetroArch doesn't support that though. Dual analogs only work in games that fully supported them, such as Ape Escape. To use dual analog for such games, go to phoenix, controllers, and change it from digital files you want to dual analog. Alternatively, open RGUI while in RetroArch and change transfer with the gamepad type in names of the Input optionsRetroArch memcard files.

===Any other distro===
You will have to compile from source. For Arch Linux , there are AUR packages that simplify this process, although it is not incredibly difficult otherwise. The most important part is making sure you have all the dependencies.
Dependencies: (refer to your distro's wiki or package manager for exact package names)'''===='''
*pkgconfig
RetroArch has a robust CLI for those who prefer the command line, there are also many pages which should have been installed by default for retro-arch, retroarch-joyconfig and others. If you use the CLI be sure to configure your retroarch.cfg file before first use. This config is well commented so each option can be fully understood. Use retroarch-joyconfig command for simplified input setup. RetroArch can auto-detect inputs, which is a great feature to simplify playing with multiple/different controllers (refer to "man retroarch-joyconfig" for details). The retroarch.cfg file should be located in /etc/retroarch.cfg, your home folder or the directory where RetroArch was installed depending on your distro and compilation setup.
For those who prefer the Phoenix-Gui, there are a slew of options - many of which are self explanatory. To keep your RetroArch dir clean and organized, be sure to setup all of the different directories in the General tab. Choose your prefered preferred video and audio options. Map your input options. Make sure you tell Phoenix where to find RetroArch if it doesn't configure automatically. Choose your core and your rom and enjoy.

If you are on a SD (not HD) crt-tube tv[[CRT TVs|CRT TV]], then you will have the best display results (proper scanlines) in 512x240 for the NES, and 512x224 for the SNES games, and 640x224 for the MDMega Drive/Genesis games.
==General set upSetup==
===Bios===
If you are going to play in a system that needs a BIOS(e.g. PS1), there's a bit more setup required. Go to 'System > General' and change the 'System directory' to where ever wherever you'd like and place the BIOS files in there.

===Mednafen PSX===
[[Mednafen]] requires you to load games through CUE sheets. Ensure that the CUE sheet is properly set up in order for the game to run. See the [[Cue sheet (.cue)]] for more.
===Super Game Boy===
<p class="de2">Download these [http://www.mediafire.com/download.php?htga58k9rumhla9 SGB-capable bsnes cores]. Then , then [http://www.its.caltech.edu/~costis/sgb_hack/sgb_bios.bin download this], place it in the RetroArch folder, and rename it as "sgb.boot.rom". Now on RetroArch, under File > Special ROM, select a Super Game Boy ROM (they will all basically work) and a Game Boy ROM. Finally, under ROM type, select Super GameBoy, make sure you have the bsnes core you downloaded selected, and play.</p> ===Dual Analog Controllers=== PS1 games often used a set of default remappings if they didn't support it directly. Some games used both analogs as the D-pad, RetroArch doesn't support that though. Dual analogs only work in games that fully supported them, such as Ape Escape. To use dual analog for such games, go to Settings > Controllers, and change it to Dual Analog. Alternatively, open RGUI while in RetroArch and change the gamepad type in the Input options. ===Transfer PS1 Memory Card Files===Mednafen creates memory card files for each individual game, whereas to PCSX-R/ePSXe where all game saves are stored into 2 memory card files. To transfer memory card files from PCSX-R/ePSXe to RetroArch: *Start game in RetroArch. *Go to system folder. Copy the names of the .mcr files created for the game.
*Place the new ones in the system folder.===Transfer PS1 memcard filesDisk Changing===To transfer memcard files:changes disks in-game, go to RGUI > Disk Options > Disk Image Append.
