* ;[[PCSX-Reloaded|PCSX-R]] is an :An open-source [[Recommended_PS1_Plugins|plugin]]-based emulator. The main reason to use this over Mednafen is that its internal resolution can be raised with little to no performance hits.** '''PGXP''' is a fork of based on PCSX-R that adds texture correctiondf, polygon wobble reduction, and polygon culling reductionitself based on PCSX. It also adds CPU overclocking and allows a hack that was originally disabled in is no longer recommended, as DuckStation has all of the same benefits of PCSX-Rwithout needing to use forks or old plugins.** :;PCSX-ReARMed is an ::An ARM port of PCSX-R, sharing a similar core, but optimized for portable handheld devices. The fork whose biggest draw is its NEON software renderer, which is both fast and accurate and has the ability to can render at higher resolutions without resorting to HLE plugins. Was given the seal of approval by Sony after being used in the official PlayStation Classic emulation box.

* ;[[XEBRA]] is an :An emulator made in Japan that has high compatibility. The UI is in Englishbut, however, since because it's not the developer's first native language , some of the naming conventions may seem weird compared to other emulators (for example , the BIOS are instead is referred to as OSROM). Luckily , there is 's a [https://www.reddit.com/r/emulation/comments/9a4mwk/xebra_guide_ps1_emulator/ guide] that helps explains how each option works. Games that require subchannel data are not supported, but most other games run flawlessly.

* ;[[No$|NO$PSX]] has :Has two versions, but standard users will want to use the cut-down gaming version. Made in the same style as [[No$|NO$GBA]], where it handles the PocketStation, it offers decent compatibility with very low spec requirements – the programmer's philosophy is to deliver a working application out of the box.

* ;[[PSX]]fin is a :A simpler emulator with a lot of compatibility issues,.<ref name="psXcompat">http://psx.silvanthalas.com/psx.html</ref> especially when using different BIOS'. Development has been halted and it remains closed-source. It's really only useful for very old toasters.

* ;[[Avocado]] is one of the few :Was slated to become an open-source PS1 emulators that does not require a pluginfull-based system and is still emulator like DuckStation, with the caveat being actively developedthat it could load games without a BIOS. That never panned out, as development has largely stopped.

* ;[[MAME]] is a very broad emulator known to support thousands :By nature of supporting arcade systems. It has a focus for accuracy, much like Mednafen, but when it comes similar to the PlayStation, MAME's "Sony PlayStation" driver (<code>psj</code>), the developers still call it is considered "preliminary", and have marked but it works; it as "Not Working". It can boot to the BIOS and launch games, but much like they say, you can expect bugs, especially between hardware revisions. The MAME project as a whole remains active, but donthere't expect it s no incentive for any of its developers to work any time soonon the PS1 driver.

* ;[[PCSX2]] is a PlayStation 2 emulator, but emulation of :Support for a hardware feature has been merged into the main project that allows the same backward compatibility with PS1 games. However, one thing to note is that backward compatibility in the original PS2 hardware didn't even cover all the games in the PS1 library, and these limitations still extend carry forward to PCSX2's emulation.
