Now, let’s get to the juicy stuff: installing the emulation core. Some games may work without a BIOS, but for full compatibility we highly recommend one. 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. You can check the default directory that Retroarch scans for BIOS files under “Settings -> Directory -> System/BIOS”. What we can tell you is that the most common bios files are: PS1 bios file corresponding to the global region of the game you want to play (US, Japan and Europe being the most common), placed into the ‘system’ folder of RetroarchĮxpanding slightly on the note of BIOS files, we can’t legally tell you where to download these.A modern Windows PC for best performance (and the most accurate guide) though RetroArch is cross-platform enough for this guide to work on other platforms.If using a non-Xbox pad, make sure you have an XInput driver/wrapper enabled. I recommend a PS3 pad for that authentic control experience or an Xbox One pad for better support. This is the case for leading RetroArch PS1 core, Beetle PSX, which we’ll be teaching you how to install and use in this article.Īlso read: How to Set Up RetroArch, The Open-Source Cross-Platform Retro Game Emulator PS1 BIOS, Gamepad, and Other Things You Needįor optimal RetroArch PS1 emulation, you’ll want the following: Some emulators, however, are actually made just for RetroArch, and because of this they may even be better than modern standalone emulators on the scene. RetroArch’s emulators, called “cores,” are generally ported emulators from other developers in the scene. Emulating games on PC usually means a full emulator and different program per platform, but RetroArch can actually emulate quite a large number of systems, all within a single program. RetroArch isn’t an emulator in and of itself – think of it as a hub for emulators and media accessible under a single, unified interface. I'm guessing off the bat (without knowing exactly how DOSBox renders the display) that it would have to change the way DSOBox renders the display to cover the black areas as well somehow if the black areas outside the display in the DOSBox window aren't currently accessible in this way with the current code.Also read: 28 of the Best Online Games to Play With Friends Meet RetroArch

It's nice for presentation for streams and YT videos but it'd also be kind of nice in real time for playing a game yourself at home as well. The idea just came to me after watching some DOS game let's play videos on YouTube. It would just display "behind" the game display like a wallpaper and spill out into the black bars/columns outside the main render area that DOSBox usually doesn't take up. Perhaps it could also have an extra CONF entry for scaling/best fit options like fill/stretch/fit/1:1 etc. Is there such thing or has anyone thought of having a feature in DOSBox where, defined in the CONF, you could add a border/background image file that would display in the black column bars around the render display (most useful for aspect ratio-corrected games)? So that, for instance, when you're playing a 320x200 aspect ratio-corrected game in 1920x1080 fullscreen resolution you could have a nice optional border around it? That could go for letterbox displays as well for that matter.
