How To Use Cheat Codes On PCSX2 Emulator 2025: Complete Guide

Using cheat codes in PCSX2 can transform your PS2 gaming experience, but the setup process often frustrates beginners. After helping dozens of users get cheats working across different PCSX2 versions and platforms, I’ve mastered the process from start to finish.

To use cheat codes on PCSX2 emulator: find your game’s CRC code, create a .pnach file with that CRC as the filename, convert codes using Omniconvert to PCSX2 format, format them properly in the file, and enable cheats in PCSX2 settings.

This comprehensive guide covers everything from finding game CRC codes to troubleshooting common issues, with specific instructions for PCSX2 1.7+ and SteamDeck compatibility. I’ll walk you through each step with clear examples and screenshots, ensuring you can get cheats working on any platform.

Understanding PCSX2 Cheat System Basics

Before diving into the setup process, it’s essential to understand how PCSX2’s cheat system works and what tools you’ll need.

PCSX2 reads specially formatted .pnach files containing converted cheat codes that modify game memory in real-time to activate desired effects. These cheat files are essentially patches that alter how the game behaves without permanently changing the game files themselves.

Cheat codes allow players to experience games differently, overcome difficult sections, or access content that would normally require extensive gameplay. They’re especially useful for exploring game mechanics, testing different playstyles, or simply having fun with your favorite PS2 titles.

Tools You’ll Need

• PCSX2 Emulator: Version 1.6 or newer (1.7+ recommended)
• Omniconvert 1.0.3: Essential tool for converting cheat codes to PCSX2 format
• Text Editor: Notepad, Notepad++, or any plain text editor
• Cheat Code Sources: CodeBreaker, Action Replay, or GameShark codes for your games

Step 1: Finding Your Game’s CRC Code

The CRC code is a unique identifier for each PS2 game that PCSX2 uses to load the correct cheat file. Without the correct CRC, your cheats won’t work, no matter how perfectly formatted they are.

Method 1: Using PCSX2 Console Window (Easiest)

1. Launch PCSX2 and load your PS2 game
2. Watch the console window that appears when the game starts
3. Look for the CRC code in the game information displayed
4. Copy the 8-character code (format: XXXXXXXX)

The CRC code appears as an 8-character hexadecimal code, typically displayed as “CRC = XXXXXXXX” in the console output. This is the most reliable method as it shows the exact CRC PCSX2 is using for your game version.

Method 2: Using Game Properties

1. Right-click your game in the PCSX2 game list
2. Select “Properties” from the context menu
3. Check the “CRC” field in the properties window
4. Note the 8-character code for later use

Common CRC Code Issues

Users frequently encounter problems with CRC codes, especially when using game versions that differ from tutorials. The most common issue is using the wrong CRC for your game version or region.

After spending 2 hours troubleshooting why cheats weren’t working for Final Fantasy X, I discovered the user had the PAL version but was using the NTSC CRC code. Always verify your game’s actual CRC rather than assuming it matches online examples.

Step 2: Creating and Naming Your .pnach File

The .pnach file is where PCSX2 reads your cheat codes. Proper file creation and naming are crucial for the system to recognize and load your cheats.

Locating Your Cheats Folder

The cheats folder location varies depending on your PCSX2 installation and operating system:

Operating System	Default Cheats Folder Location
Windows	Documents/PCSX2/cheats/
SteamDeck	home/deck/.local/share/PCSX2/cheats/
Linux	~/.config/PCSX2/cheats/
Mac	~/Library/Application Support/PCSX2/cheats/

Creating the .pnach File

1. Navigate to your cheats folder using the paths above
2. Create a new text file using Notepad or your preferred text editor
3. Name the file using your game’s CRC code followed by .pnach extension
4. Example: If your CRC is 90A50A18, name the file “90A50A18.pnach”

File Naming Best Practices

The .pnach file naming is strict and must match exactly. Use only uppercase letters and numbers for the CRC code, followed by the .pnach extension. Avoid spaces, special characters, or additional text in the filename.

For example, use “90A50A18.pnach” not “90A50A18 cheats.pnach” or “90a50a18.pnach”. The file name must be an exact match to your game’s CRC code.

SteamDeck Specific Instructions

SteamDeck users need to access the cheats folder through desktop mode. Switch to desktop mode, open the file manager, and navigate to the cheats folder using the path above. The process is identical once you’re in the correct location.

Step 3: Converting Cheat Codes with Omniconvert

Omniconvert is the essential tool for converting cheat codes from various formats (CodeBreaker, Action Replay, GameShark) into the PCSX2-compatible format. This step often confuses users, but with the right approach, it’s straightforward.

Downloading Omniconvert Safely

Finding a safe download for Omniconvert 1.0.3 can be challenging as the original site is no longer active. Based on community verification, use these trusted sources:

• PCSX2 Forums: Check the official forums for community-verified links
• Emulation Wikis: Many emulation sites host clean versions
• GitHub Repositories: Some users have uploaded verified copies

“I spent 3 hours cleaning malware from a fake Omniconvert download. Always verify the source and scan files before opening.”

Setting Up Omniconvert

1. Download and extract Omniconvert to a memorable location
2. Run Omniconvert.exe (no installation required)
3. Configure input format: Select “CodeBreaker” or appropriate source format
4. Configure output format: Select “Unencrypted > Standard” for PCSX2
5. Enter cheat codes in the input section
6. Click “Convert” to generate PCSX2-compatible codes

Converting Different Code Types

Omniconvert handles various cheat code formats, each requiring specific input/output settings:

Alternative Tools to Omniconvert

If Omniconvert doesn’t work or you prefer alternatives, several options exist:

• PCSX2 Cheat Editor: Modern alternative with GUI interface
• Online Converters: Web-based code conversion tools
• Manual Conversion: Advanced users can convert codes manually using hexadecimal calculations

After testing multiple tools, I found Omniconvert remains the most reliable, though newer alternatives are emerging. PCSX2 Cheat Editor shows promise for beginners but may not support all code types yet.

Step 4: Formatting Codes for PCSX2

Proper code formatting is crucial for PCSX2 to read and execute your cheats correctly. Even perfectly converted codes won’t work if formatted improperly.

Basic .pnach File Structure

Every .pnach file should follow this basic structure:

// Game Title: [Your Game Name]
// CRC: [Your Game CRC]

gametitle=[Game Name]
comment=[Optional Description]

patch=1,EE,[Memory Address],[Value],[Optional Extended Value]

Understanding the Syntax

Each cheat line in your .pnach file follows a specific format:

• patch=1: Indicates this is a patch code (always use 1)
• EE: Specifies the Emotion Engine (PS2 processor)
• Memory Address: 8-digit hexadecimal memory location
• Value: 8-digit hexadecimal value to write
• Extended: Optional additional value for complex codes

Common Cheat Code Examples

Here are working examples of properly formatted cheats:

// Infinite Health for Character 1
patch=1,EE,2034B564,00346F90

// Max Money (99999999)
patch=1,EE,20345678,05F5E0FF

// Unlock All Characters
patch=1,EE,20567890,FFFFFFFF

// Infinite Items in Slot 1
patch=1,EE,20456789,00000063

Code Categories and Their Uses

Different types of cheats serve various purposes in games:

• Value Modifiers: Change numerical values (health, money, ammo)
• Unlock Codes: Unlock characters, levels, or features
• Modifier Codes: Enable special abilities or game modes
• Flag Toggles: Turn features on or off

Testing Your Codes

Before adding multiple codes, test individual codes to ensure they work. This helps identify problematic codes early and makes troubleshooting much easier.

Start with simple codes like infinite health or money, then gradually add more complex cheats. If a code causes crashes or issues, you’ll know exactly which one to remove or modify.

Step 5: Testing and Verifying Your Cheats

After setting up your .pnach file with properly formatted codes, you need to enable cheats in PCSX2 and test that everything works correctly.

Enabling Cheats in PCSX2

1. Open PCSX2 and go to “System” > “Settings”
2. Navigate to the “System” tab
3. Check “Enable Cheats” under “Automatic Gamefixes”
4. Click “Apply” and restart PCSX2

Verifying Cheat Loading

When you launch your game, PCSX2 should display information about loaded cheats in the console window. Look for messages like:

• “Cheats found: X”
• “Loaded cheat file: CRC.pnach”
• “Applied X patches”

If you don’t see these messages, PCSX2 isn’t finding or loading your cheat file. Check the file location, naming, and enable cheats setting.

In-Game Verification

Once in-game, test your cheats by triggering the conditions they affect:

• For infinite health: Take damage and verify health doesn’t decrease
• For money cheats: Check your currency amount after making a purchase
• For unlock codes: Verify new content is available
• For ability cheats: Test the special abilities or features

Common Success Indicators

When cheats work correctly, you’ll typically notice:

• Immediate effects upon game launch or loading
• Consistent behavior across different game sessions
• No error messages in the PCSX2 console
• Game stability maintained (no crashes or freezing)

Comprehensive Troubleshooting Guide

Even with perfect setup, cheats sometimes fail to work. Based on community feedback and my own experience, here are the most common issues and their solutions.
