Mewgenics Save Editor vs Trainer: Best Cheats Guide (2026)

If you’ve spent any time with Edmund McMillen games, you know they don’t hold your hand. Like The Binding of Isaac before it, Mewgenics is a punishing roguelike simulation where one bad turn can wipe out generations of careful breeding. I learned this the hard way when my prize-winning cat, ‘Sir Pounce,’ died of a preventable disease just because I was short on cash. That frustration led me down the rabbit hole of cheating: should I surgically alter my save file, or just brute-force the game with a trainer?

Mewgenics Save Editor vs Trainer: Which is Better?

Choosing between a save editor and a trainer depends entirely on your goal: do you want to carefully craft the perfect cat, or do you want to dominate battles instantly? While trainers offer immediate gratification, save editors provide a level of permanence that memory injection cannot match. In my testing across multiple playthroughs, I found that trainers are excellent for skipping the grind, but they can’t handle the complex genetic algorithms that determine your cat’s offspring.

Pros and Cons of Mewgenics Save Editing

Save editing gives you surgical precision. You can open your save file and modify the exact hex values corresponding to a cat’s tail length, fur pattern, or hidden genetic traits. This is ideal for players who want to bypass the breeding RNG to create a specific “super cat.” However, the risk is significant: one wrong digit can corrupt the entire save file, forcing you to start over if you haven’t made a backup. I prefer this method when I want to experiment with specific gene combinations that would take dozens of hours to breed naturally.

Pros and Cons of Using a Mewgenics Trainer

Trainers are far more user-friendly. You simply launch the tool, press a hotkey, and instantly get infinite money or full health. This is perfect for surviving tough battles or experimenting with expensive items without grinding. The downside is that trainers can sometimes cause crashes during complex animations, like breeding sequences, because the game logic conflicts with the forced memory values. In my experience, trainers are best used for resource gathering, while save editors are best for roster management.

How to Edit Mewgenics Save Files Safely

If you decide to go the manual route, safety is paramount. Mewgenics uses a specific file structure that can be fragile if mishandled. Before you change a single byte, you need to know exactly where your data is stored and how to protect it. I’ve corrupted my fair share of saves by rushing this process, so follow these steps carefully.

Where is the Mewgenics Save File Location?

For most Windows users playing on Steam, the save files are located in the standard Steam userdata folder. You will need to navigate to the following path:

If you are playing a non-Steam version or have Steam Cloud saves disabled, check the local AppData folder:

Step-by-Step Guide to Editing Your Save

Editing your save file isn’t as scary as it sounds if you have the right tools. Here is the exact workflow I use to modify my currency and items:

1. Backup Your Data: Copy the entire `remote` folder to your desktop. Do not skip this. If you break the file structure, the game will reset your progress.
2. Download a Hex Editor: You will need a tool like HxD or a specialized hex editor to read the binary data. Notepad usually corrupts the formatting.
3. Locate the Value: Open your save file in the editor. Search for your current money value. Note that you may need to convert your money amount to hexadecimal first to find it.
4. Modify and Save: Change the value to your desired amount (e.g., FF FF for 65,535). Save the file and close the editor.
5. Launch the Game: Start Mewgenics. If the game loads, you’re golden. If it crashes, delete the modified file and restore your backup.

Modifying Cat Stats and Unlockables

When opening the save file with a hex editor or a specialized JSON editor (if the format allows), look for strings labeled “stats” or “inventory.” Be careful with values; changing a stat to “9999” might look fun, but if the game’s UI only supports three digits, this can cause visual glitches or crashes. Stick to reasonable limits that the game engine can handle. I recommend increasing stats by small increments (e.g., +10) to test stability before going full god-mode.

Using a Mewgenics Infinite Money Trainer

For players who prefer a hassle-free experience, a trainer is the way to go. This method injects code directly into the game’s memory while it runs, allowing you to toggle cheats on and off instantly without touching any files.

Can You Use Cheat Engine in Mewgenics?

Yes, Cheat Engine works well with Mewgenics. To use it, you need to attach the Cheat Engine process to the game executable while it’s running. Then, you can scan for values like your current money, change them in-game (by buying or selling an item), and scan again to narrow down the address. Once found, you can freeze the value or change it to whatever you want. This is particularly effective for freezing your Action Points during combat, giving you infinite turns.

Recommended Mewgenics Trainers

If manual scanning sounds tedious, XMODHUB offers a pre-configured solution. The XMOD trainer simplifies the process into a clean interface where you can activate powerful cheats with a single click.

These featured mods are just the beginning. Whether you’re looking to skip tedious grinding, experiment with different playstyles, or speed up your progression, XMOD’s comprehensive toolkit offers dozens more options tailored to your playstyle.

Troubleshooting Trainer Crashes

If your trainer crashes the game, it’s usually due to a version mismatch. Game updates often change memory addresses, rendering old trainers obsolete. Always ensure you are using a trainer version that matches your game patch. Additionally, antivirus software may flag the trainer as a false positive due to its memory injection behavior; adding an exception usually resolves this.

Common Mistakes When Cheating in Mewgenics

Even experienced cheaters can run into trouble. Avoiding these common pitfalls will save you from frustration and lost progress.

Why Your Mewgenics Cheats Stop Working

The most common reason for cheats failing is a game update. When developers patch bugs or add content, the internal memory map shifts. This breaks the “pointers” that trainers use to find values like health or money. If your cheats suddenly stop working, check for a trainer update or try finding the new memory addresses manually with Cheat Engine.

Avoiding Corrupted Cat Genetics Data

One specific danger in Mewgenics is editing “dead” cats. The game often retains data for deceased cats in the save file for lineage purposes. I once attempted to resurrect a dead cat by flipping its “is_dead” boolean from 1 to 0. The result? The game loaded, but every time I entered the breeding screen, it crashed to desktop. The game logic couldn’t reconcile a dead cat being alive in the roster. Stick to editing active, living cats to ensure stability.
