Ultimate Emulator / System

PlayStation

Your discs. Your BIOS. Rendered up to 8x.

RazorPS1 plays PlayStation disc images with DualShock controls, shared memory cards and internal resolution up to 8x. It needs a PlayStation BIOS you provide, and the BIOS's region decides which discs run.

01 / Current support

Where PlayStation stands today.

Status describes the core, not every game. Compatibility is always title-dependent.

Supported
Owner acceptance is recorded for the core or named play mode; compatibility remains title-dependent.
Core
RazorPS1, a first-party core included with Ultimate Emulator. It is chosen automatically for PlayStation games.
Optimized
A specific owner-accepted optimization milestone exists for this core.
Release note
BIOS required. Enhanced resolution uses the software renderer; full speed is not guaranteed.
Cheats
Free. In the Game Menu's Cheats section, choose + Add Cheat Code and enter a code you have. There is no built-in cheat list, and cheats are switched off in online multiplayer sessions.

02 / Your collection

The files it plays.

These are the PlayStation game files RazorPS1 opens. Ultimate Emulator does not supply games; add them from your own collection.

03 / Firmware & BIOS

A BIOS you provide.

PlayStation games cannot start until its BIOS is added. You add it once, and Systems shows Ready.

Required
Any 512 KiB PlayStation BIOS is accepted, and the region it is for decides which discs will run, so use a BIOS for the same region as your games. The application's What file do I need? lists the versions it recommends for each region.

  1. Open Manage BIOS

    In Systems, select PlayStation and choose Manage BIOS. Its firmware page lists each file the system uses and whether it is required.

  2. Choose the file you own

    Check What file do I need?, then use Choose BIOS File, or Choose Firmware Folder if you keep your firmware together.

04 / Input

How it plays in your hands.

Connect a controller and it is mapped automatically. Change the layout for every game, for this system only, or for a single game in Settings → Controllers.

PlayStation in Ultimate Emulator

  • Two controllers, with DualShock analog sticks, rumble and the Analog button.
Controller Setup

05 / Picture

Sharper than the original, if you want it.

Window mode, Fit and Integer Scale, aspect ratio, pixel filtering and effects come from Settings → Graphics, for every system or for one game.

Internal Render Resolution
Native, 2x, 4x, 6x, 8x. Higher steps draw the game itself at a higher resolution and ask more of your graphics card.
Renderer
Shown for information. The system's built-in engine chooses how it draws, with a safe fallback.

06 / Your progress

In-game saves and save states.

07 / Play together

Together on one PC, or across two.

A system profile does not make a single-player game multiplayer. The game decides how many can play.

On one PC
Up to 2 players, one controller each, in games made for more than one player. No account needed.
Across PCs
Native Multiplayer for two players, with ROM Mode. Each PC runs the game and the players' inputs are shared. Online sessions need Premium for everyone taking part.
Multiplayer

08 / Honest compatibility

What to know before you play.

Current limits of the included core, as of this release.

Known limitations

  • Compressed and container disc formats, including CHD, PBP, ECM, NRG, MDF and M3U playlists, are not opened. Use .cue with .bin, .img or .iso.
  • Enhanced (internal) resolution runs on the software renderer. 2x and 4x are faster in this release, but full speed is not guaranteed.
  • Save states made with earlier versions of Ultimate Emulator cannot be loaded in this release. They stay on your PC, and memory-card saves are not affected.
  • Compatibility is still incomplete: some games do not run correctly yet.
Region
Set by your BIOS: the region it is for decides which discs will run.
