If you want to add cheats to RPCS3, the easiest method is usually through its game patch system. RPCS3 doesn’t work like an old cheat device where you simply type a code into a separate cheat box. Instead, compatible cheats are normally handled as patches that change certain parts of the game while it is running.
Some patches are already available through RPCS3’s Patch Manager, while others may need to be added manually through a patch.yml file. The important part is matching the patch with your exact game version. A cheat made for a different update or region may simply do nothing, or it may make the game unstable.
How Do Cheats Work in RPCS3?
RPCS3 uses game patches to make changes to PlayStation 3 games. A patch can change gameplay values, remove limits, alter graphics, unlock higher frame rates, or act like a traditional cheat depending on what it was made to do.
Under the hood, these patches can change specific instructions or values used by the game. You don’t need to understand all of that just to use them. What matters more is that the patch was made for your exact game build and that RPCS3 recognizes it correctly.
This is also why you will see normal performance patches mixed with things people call cheats. They use the same general patch system, but they don’t all serve the same purpose.
Before Adding Cheats: Check Your Game Version and PPU Hash
Before installing a custom cheat, check which version of the game you are running. Two copies of the same game can have different executable data because of region differences or game updates.
RPCS3 can identify the game’s executable with a PPU hash. Its patch documentation explains that you can boot the game once, then check RPCS3.log for the PPU executable hash.
A simple way to check it is:
- Start the game once in RPCS3 and let it reach the main menu. This gives RPCS3 a chance to load the executable and write the needed information to its log.
- Close the game normally. You don’t need to play for several minutes because the executable information should already have been recorded.
- Open the RPCS3.log file with a text editor. Use search and look for PPU executable hash.
- Copy the hash shown for the game. Keep it nearby so you can compare it with the cheat or patch you plan to use.
Also check the game’s title ID if the patch lists one. Codes such as BLUS or BLES can help identify different releases, but the executable hash is much more useful when a patch specifically depends on it.
How to Add Cheats Using RPCS3 Patch Manager
Start with Patch Manager before manually editing files. If a compatible cheat or gameplay patch is already available there, this is much easier and leaves less room for formatting mistakes.
Open RPCS3 and find its game patch management option. The exact menu wording can change between emulator builds, but you are looking for the area where RPCS3 lists available game patches.
Find your game and look through the patches attached to it. Read the description before enabling anything because a game may have performance fixes, graphics changes, and gameplay patches listed together.
Enable only the cheat you want to test first. Then close the patch window if needed and boot the game.
Don’t switch on ten patches immediately. If the game crashes or starts behaving strangely, you won’t know which patch caused it. One at a time is slower for a minute, but it saves a lot of messing around later.
How to Add a Custom Cheat With patch.yml
If the cheat is not available through the normal patch list, you may come across a custom RPCS3 patch shared as YAML text. Older RPCS3 patch documentation uses a patch.yml file in the RPCS3 root folder for this type of manual patch.
Before changing anything, close RPCS3. Then locate the folder where RPCS3 itself is installed or stored.
If a patch.yml file already exists, make a copy before editing it. If your patch instructions specifically require a manual patch.yml and the file doesn’t exist, create it with a normal text editor and make sure the filename does not accidentally become patch.yml.txt.
Paste the compatible patch entry into the file exactly as provided. YAML cares about spacing and indentation, which means moving one line a few spaces can stop the patch from being read correctly.
After saving the file, reopen RPCS3. Open the patch management area again and check whether the new patch appears. Enable it, boot the game, and test the feature it is supposed to change.
Do not take a cheat for one version of a game and simply paste it into another version because the title looks the same. The memory locations can be different.
How Does an RPCS3 Patch Entry Work?
A manual patch can look intimidating because it contains hashes, addresses, values, and YAML formatting. You do not need to memorize the format to use an existing patch safely.
A simplified example might look something like this:
This is only an example of the general idea, not a real cheat for a game.
The PPU section identifies which game executable the patch belongs to. The line underneath tells RPCS3 what type of value is being written, where the change happens, and what value should be placed there.
Real patches can be much longer. Some change one value while others modify many addresses to make a feature work.
If you are using a patch made by someone else, keep its formatting exactly as supplied. Guessing new memory addresses or changing values without knowing what they do can easily make the game crash.
How to Enable or Disable a Cheat
Once RPCS3 recognizes the patch, you normally don’t need to keep deleting and recreating the patch file. Open Patch Manager and use the available checkbox or enable option for that patch.
If a cheat causes trouble, disable it and restart the game. Restarting matters because a patch may already have changed something in memory during the current session.
Some gameplay cheats can also change data that gets written into your save. For example, a cheat that changes money or inventory may leave those values in the save even after the patch itself is disabled.
So turning off a cheat does not always undo everything it did earlier. Keep that in mind before testing something on a save you care about.
Why Is My RPCS3 Cheat Not Working?
When a cheat appears to do nothing, don’t immediately assume the patch is broken. Version mismatch is one of the first things worth checking.
Go through these points:
- Make sure the patch was written for your game version
- Compare the required PPU hash with your current one
- Check that the correct cheat is enabled in Patch Manager
- Make sure patch.yml is in the right RPCS3 location if you added it manually
- Check the YAML indentation
- Confirm the patch supports your game region or release
- Restart RPCS3 after changing a manual patch
- Check whether another enabled patch may conflict with it
A typo inside YAML can be enough to stop a manual patch from loading. This is why copying the patch exactly is better than rewriting it by hand.
The game update matters too. If a cheat worked last month and stopped after you installed a title update, check the PPU hash again before changing anything else.
Why Did a Cheat Stop Working After a Game Update?
A PlayStation 3 game update can change its executable. When that happens, addresses or instructions used by an older cheat may no longer be in the same place.
That does not mean every update breaks every RPCS3 patch. Some still work fine. But if a cheat suddenly stops after updating the game, version compatibility should be one of your first checks.
Boot the updated game and get the current PPU hash again. Compare it with the version listed by the patch author.
If they do not match, look for a patch made for the newer game build. Trying to force an old memory patch onto the wrong executable is not a good fix.
Should You Back Up Saves Before Using RPCS3 Cheats?
Yes, especially if the cheat changes anything that can become part of your save data. It takes very little time and gives you an easy way back if the result is not what you expected.
A money cheat, inventory change, item unlock, or progression patch can leave permanent values in the save. Even after you disable the cheat, the game may keep whatever was already saved.
Performance patches are a little different. Something like an FPS or visual patch usually changes how the game runs rather than your progress, though any unstable patch can still cause crashes.
For gameplay cheats, make a copy of important saves before testing. If you have a long playthrough with dozens of hours in it, don’t use that as your experiment file.
How to Prevent RPCS3 Cheat Problems
Once you have cheats working, keeping the setup clean makes future problems much easier to solve. You don’t need a complicated system, just keep track of what belongs to which game build.
A few habits help:
- Match cheats with the exact game version and PPU hash
- Keep a backup of your working patch.yml
- Enable one new cheat at a time
- Back up important saves before gameplay-changing patches
- Check patch compatibility again after installing a game update
- Avoid enabling several patches that change the same part of a game
- Keep a note of which patches you enabled for each title
- Disable a problem patch before changing unrelated emulator settings
Try not to update a game, change RPCS3 settings, add five cheats, and update the emulator all in one session. If something breaks after that, figuring out the cause becomes much harder.
Final Thoughts
To add cheats to RPCS3, start with the Patch Manager and use an existing compatible patch when one is available. For custom cheats, you may need a manual patch.yml, but check your game version and PPU hash before adding anything. RPCS3’s own patch documentation also ties manual patch entries to specific PPU executable hashes, so that match matters.
Most problems come down to a patch being made for another game build, incorrect YAML formatting, or the cheat simply not being enabled. Test one patch at a time and keep a save backup if the cheat changes money, inventory, progression, or other permanent game data.
If your cheat still isn’t working, comment with one detail: does the patch appear inside RPCS3 Patch Manager but do nothing, or does it not appear in Patch Manager at all?
