I read through this and am still confused on how to get my old 3ds xl to run PS1 games on retroarch. I downloaded the .3dsx files from here
http://buildbot.libretro.com/nightly/nintendo/3ds/ , then I ran it on my homebrewed 3ds and can see all the cores (pcsx rearmed, pocket snes,catsfc libretro,...). I then run the pcsx rearmed and the bottom screen has a bunch of stuff, one of which is labled [WARN], it says" "libretro_path" is a directory, using this for "libretro_directory" instead ". The top screen shows a menu giving me the following options: Start Core, Load Content Load Recent Settings, Information, Restart RetroArch, Load Configuration, Save Current Config, Save New Config, Help, Quit RetroArch. Nothing happens when I select Start Core. Retroarch freezes when I select Load Content. I have some PS1 roms in the .bin format. I've tried lots of things, and nothing has worked for me. I really want to be able to play my PS1 games on the old 3ds xl, but nothing is working. Can anyone please help me?
