Getting Started with PCSX2

Back to the Top

PCSX2 is a fairly straight-forward emulator to set up. Place your ROMs in Emulation/roms/ps2. Place your BIOS directly in Emulation/bios. Read the Configuration section to learn more about PCSX2 and its folder locations.

To launch your ROMs in game mode, use Steam ROM Manager and use one of the following parsers to play your PS2 ROMs:

  • EmulationStation-DE
  • Sony PlayStation 2 - PCSX2
  • Emulators

PCSX2 Configuration

      • inis

Common Issues

Back to the Top

Controller isn't working?

Back to the Top

Try turning off multitap. Certain games may not handle it.

  1. Open PCSX2-QT
  2. Open the Controllers settings menu
  3. Disable Multitap

Black screen immediately or just after the game boots?

Back to the Top

This indicates a bad dump. Please validate and redump your game files.

How to validate your ROMs: https://github.com/dragoonDorise/EmuDeck/wiki/frequently-asked-questions#how-to-verify-a-rom-is-valid

After starting a game it goes back to Steam or EmulationStation-DE?

This usually means you haven't placed your bios in the right place.

Why do some of my multi-disc games not show up in Steam ROM Manager?

Back to the Top

Primarily with the Playstation 2 parser, turning on Remove (...) and [...] brackets will trim the ROM name and cause Steam ROM Manager to deem multiple discs of the same game as the same file. When you generate an app list, only one of your discs will show up.

To fix this, do one of the following solutions:

  • Remove the () in the file name
    • Open the respective folder with the ROMs, and rename each disc to remove the ()
    • Example:
      • Original File Name: Xenosaga: Episode 2 (Disc 1) and Xenosaga: Episode 2 (Disc 2)
      • Updated File Name: Xenosaga: Episode 2 Disc 1 and Xenosaga: Episode 2 Disc 2
  • Turn off Remove (...) and [...] brackets in the respective parser
    • Visual Reference (Using Playstation 2 as an example):
    • Note: With this setting off, Steam ROM Manager will include any content in the parantheses of the file name when parsing ROMs. This means that if you include region names or any other information in parantheses, your ROM will include this information in a generated app list

How to Optimize Performance (Power Tools)

Back to the Top

Visit https://github.com/dragoonDorise/EmuDeck/wiki/EmuDeck-Application-101#power-tools to learn how to optimize performance using Power Tools.

How to Optimize Storage (Compression Tool)

Back to the Top

To optimize storage, you can use the EmuDeck Compressor within EmuDeck.

The EmuDeck Compressor will compress your Playstation 2 ROMs from ISO or BIN/CUE to CHD. If your ROM is a BIN/CUE, the Compression Tool will only compress it if you have both the BIN and the CUE files for a ROM. If the ROM is in a zip file or is missing a paired BIN or CUE file, the Compression Tool will not detect the ROM.

After running the EmuDeck Compression Tool, re-run Steam ROM Manager to update your ROM shortcuts to the newly compressed ROM.

How to Manage Multiple Discs

Back to the Top

PCSX2 does not support M3U files.

You can manage multiple discs two ways:

Method 1: Hotkeys

  1. While in game, when you are ready to switch discs, press Start + L3 at the same time
  2. Select Change Disc and select your next disc

Method 2: Separate Game Entries

  1. When you are ready to switch discs, save and exit out of your game
  2. Open the next disc entry, either as a separate shortcut through Steam ROM Manager or a separate entry through EmulationStation-DE

How to Switch to Folder Memory Cards

Back to the Top

By default PCSX2 stores each memory card as a single file. This doesn't have any compatibility problems, but means that once you hit the 8MB limit you'll have to start manually swapping cards. You can get around this by converting to folders for your memory cards:

  1. Open PCSX2
  2. Settings menu > Memory cards
  3. Eject the memory cards you wish to convert, by clicking the appropriate eject icons near the top of the window
  4. Right click each card to convert, and select "Convert"
  5. Ensure the conversion type dropdown is set to "Folder" and click OK
    1. This process will create a new folder that is a copy of the original memory card file. The file will be left intact as a backup.
  6. Right click the newly converted memory card folder, and select Use for slot 1/Use for slot 2 as appropriate
  7. At the bottom of the window, ensure "Automatically manage saves based on running game" is checked

PCSX2 will now give each game it's own separate memory card automatically.

How to use Cheats

Back to the Top

Important

Individual Widescreen and "No Interlace" cheats are no longer supported. These are now officially bundled with PCSX2 and can be enabled in the per-game settings menu. For a tutorial on how to use these in PCSX2, read https://github.com/dragoonDorise/EmuDeck/wiki/PCSX2-QT#how-to-use-widescreen-or-no-interlace-cheats.

For more detail, read https://forums.pcsx2.net/Thread-Sticky-Important-Patching-Notes-1-7-4546-Pnach-2-0

Note: This change means that the cheats_ni and cheats_ws are no longer used by PCSX2. Do not use these folders. PCSX2 will not recognize any files placed in these folders.

Cheat Resources

This list is not comprehensive

You can find more information about PCSX2 cheats here: https://wiki.pcsx2.net/Game_cheats.

Tutorial

Information on Cheats

Cheat files have a .pnach file extension. Sometimes websites will provide the raw content of a cheats file. You can copy and paste these contents into a text file, and save the file as CRC-descriptivename.pnach.

The website will usually provide the crc as an 8 character long alphanumerical string. Replace the CRC with the alphanumerical string and replace the descriptive name with the function of the cheat.

For example, a Controllable Party Members cheat for Persona 3 FES could be named: 94A82AAA-Controllable Party Members.pnach

Preparing the Cheat File

This section goes over identifying and creating headers for your cheats. Creating headers is not necessary to do but allows for easier cheat management in PCSX2. Headers allow you to toggle cheats on a per-cheat basis and allow you to identify your various cheats directly in PCSX2's GUI.

  1. Download the cheat file
  2. Open it in a text editor of your choice
  3. Check to see if the cheat file has headers at the top of each cheat bundled in the file.
    • The header is typically the name of the cheat in [] with an optional description or author
      • For example: 
        •   [Controllable Party Members]
  author=TGE
  description=This cheat allows you to control your party members in Persona 3 FES
  4. If the cheat file does not have headers, you can manually add them
    • The header is not required but allows you to toggle cheats on a per cheat basis in PCSX2
    • Note: If a cheat file has multiple sections for the same cheat, you can choose to add one header at the top of the file. This header will treat the cheat file as one cheat in PCSX2
    • You can now split cheats out into multiple files
      • Use the format: CRC-descriptivename.pnach
    • To add headers, use the following format, note that the author and description fields are optional: 
      •   [NAMEOFCHEAT]
  author=NAMEOFAUTHOR
  description=DESCRIPTIONOFCHEAT

For an example of a full cheat file with a header: https://gist.githubusercontent.com/rawdatafeel/4ac815f27ace770a84fe1ad7937355c7/raw/ddcacfaf9a0ebf930d27f95c86507cd89e2db704/94A82AAA-Controllable%2520Party%2520Members.pnach

How to Use the Cheat File

  1. Place your cheat file, with a .pnach file extension in /home/deck/.config/PCSX2/cheats
    • ~/.config is an invisible folder by default. In Dolphin (file manager), click the hamburger menu in the top right, click Show Hidden Files to see these folders
  2. Open PCSX2-QT
  3. Click the fullscreen button in the top right
  4. Right click a game, click Properties

If you are using the Big Picture GUI:

  1. Click the frowny face
  2. Toggle the Enable Cheats button
  3. Toggle the cheats you would like to use
  4. Repeat as needed

If you are using the Desktop GUI:
