Recommended PS1 plugins

Emulator

'Firstly, stop using ePSXe and use' PCSX-R.

Graphics

• 

  Having problems? Try these settings.
  3D: PEOPS OpenGL 1.78 - Comes with PCSX-R. Has an anti-jitter function labeled "GTE accuracy", and allows driver-forced AA.
• OpenGL 2.9 - Use if you run into problems with 1.78, or want to use shaders. It allows you to set a custom rendering resolution for within the fullscreen box, aka window resolution.
• 2D: gpuBladeSoft 1.41 - Very accurate and has a lot of options for enhancements and shaders, but renders everything on CPU so can be very demanding at high resolutions. Fairly buggy past native rendering resolution as well, with texture misalignment issues and whatnot.

Sound

• P.E.Op.S 1.10 beta
• Eternal SPU 1.5

Input

• LilyPad latest SVN Old shit(under Input APIs set Keyboard API to Raw Input)
• LilyPad-SCP (Comes with the driver, which is a very nice alternative to MalwareinJoin)
• Pokopom Xinput Pad Plugin 2.0
• LilyPad-MotioninJoy (if you've a DS3 and are using MiJ)

Bios

Don't use simulated BIOS, download and use a real BIOS. Pretty much any BIOS file in that package will work.

No plugins

These PS1 emulators do not use plugins.

• XEBRA,
