For example Neogeo takes the bios files just like PSX in the rom system folder and system folder in the retroarch install folder. But if you want others there’s a lot more work. Now there are specifically about 10-14 systems that work this easily. ⁠⁠⁠Once you find a good core for the system go to configuration and then playlists and edit that game playlist there should be a setting somewhere to do that and in there you should find set core association for that playlist and choose the good core.If that core doesn’t work exit and close the content try launching it again with a different core. ⁠⁠⁠Go to the specific playlist for your system choose a game and associate a core with the game.⁠⁠⁠Go to playlist and choose import content and have it scan your main rom folder.If your controller still isnt configured, you might need to go to Settings, then Input, then.

⁠⁠⁠Place all roms you want to use in retroarch in one main folder with sub folders for the specific systems and then the roms in those folders. Quit and restart RetroArch to see if your controller was found.⁠⁠⁠Go to configuration and hot keys and set a easy to use button code configuration to menu.⁠⁠⁠Go to download cores and go through every system you want to use and download every core for it.⁠⁠⁠Launch retroarch for the first time, go to updates and download all updates except cheats.If you’ve followed up to to this point, your controller is ready to use, and you’ve acquired the PS1 bios file (s) that you’ll need to play your games. I recommend setting 元 + R3 as your shortcut. No matter what system you’re trying to run it on operationally it’s the same setup which is why I put together this guide. Now, use Left/Right on your D-Pad to select a Menu Toggle Gamepad Combo. This guide works for Android and PC, PS3 and Xbox One/Series versions… as I’ve tried the same methodology on all and they are the same as long as your retroarch version is up to date. I spent some time recently going through multiple Android devices and getting it setup, as well as on my modded PS3 and in my Xbox One in Retail mode and I came up with the following. It’s the recommended emulation system by a lot but it’s not user friendly.
