Video Game Emulation Wiki

ePSXe is a closed source, plugin-based PlayStation emulator offering high compatibility but relying heavily on contributions not directly affiliated on the project.



ePSXe is a plugin-based PlayStation emulator (includes internals plugins for sound and CD-ROM, and GPU in Linux and Android versions). It supports multiple CD-ROM formats (bin/cue, multibin/cue, mdf/mds, ccd/bin/sub, iso, ecm, pbp, etc), including subchannel support and PPF patching on the fly. The newer version (ePSXe 2.0) now supports pad plugins. Multitap up to 8 players are supported too.

There are versions for Windows (free), Linux (free) & Android (pay)

PC version 1.9.25 introduced HLE support, so an original PlayStation BIOS is not absolutely required anymore. However, a real PlayStation BIOS is recommended as the HLE is known to break some games.

Currently there is a known bug with the Windows version- the emulator does not have the CPU overclocking option set to 1x by default, so the user must select it manually otherwise the emulator will freeze or crash upon starting a game.


ePSXe uses Kaillera clients. Alternatively, You can use Evolve HQ for the local netplay function (2 players only) [ePSXe 2.0.5]



  • Support for up to 8 simultaneous people playing
  • No fiddling with router settings and port forwarding
  • NetPlay traffic is handled by a central dedicated server that helps keep things synched
  • Private game chat support and public chat to speak people outside your game room
  • Being able to drop out of a game at any time without disrupting (much) your teammate(s).
  • Kicking/banning/muting people from your room
  • It's a matchmaking service where you can join other people's rooms, too


  • It's slightly (significantly still) prone to freezing/crashing/BSOD (in that order)
  • Random, inconsistent FPS drops due to the server trying to keep everyone synched, sometimes stuttering. It's annoying, but rarely does it make it unplayable
  • The emulator is based upon (ePSXe 1.60, a 10 year old version) lacks A LOT of options, and incorrectly emulates several games
  • Everyone needs to have the exact same ROM version or NetPlay won't work (if it somehow does, it'll desynch rather quickly)
  • Everyone needs to have the exact same save file, or no save file at all. Else, it desynchs
  • You need to constantly switch focus back and forth between chat and emulator window in order to chat.
  • You will hear no sound while the window is unfocused.
  • The emulator is extremely sensistive and desynchs if you focus on another window, move the window around or minimize it
  • Not long after the game desynchs, the entire emulator will freeze
  • Dropping from a game or trying to exit Kaillera will freeze or crash the game


  1. Unpack the emulator wherever you want.
  2. Replace the stock kailleraclient.dll inside the emulator folder with the multiplayer version (Jul-2011) IF you want to play with more than 2 players, OR you have horrible ping while using the P2P version.
