My Best Friend’s Sister Reset Progress Guide (2026)

Complete My Best Friend’s Sister Reset Progress Guide

Resetting a visual novel like My Best Friend’s Sister isn’t as straightforward as other genres. Because the game tracks global data—like which scenes you’ve unlocked and which text you’ve already read—simply starting a new game doesn’t wipe the slate clean. You might find yourself starting a “new” game only to realize the “Skip” button is still fast-forwarding through dialogue you supposedly haven’t seen yet.

Using the In-Game Menu to Restart My Best Friend’s Sister

The standard “New Game” option is the safest way to restart the story, but it has limitations. When you select “New Game” from the main menu, the game creates a new instance of the story variables, but it keeps your global “persistent” data intact. This means the game still remembers that you’ve seen certain scenes, so the “Skip Unread Text” feature will still skip over dialogue you read in your previous playthrough.

If your goal is just to make different choices, this method is fine. But if you want a “virgin” experience where the game treats you like a brand-new player, the menu options won’t cut it. You need to perform a manual deletion of the system files.

Understanding the Ren’Py Persistent Data System

To understand why a simple reset doesn’t work, you need to know a bit about the engine. My Best Friend’s Sister runs on Ren’Py, which separates data into two buckets:

• Save Slots: These are individual files (like 1-1-LT1.save) that record your current location, inventory, and immediate choices. Deleting these only removes your ability to “Load” that specific moment.
• Persistent Data: This is a single global file named persistent. It stores the “meta” information: which endings you’ve achieved, which gallery images are unlocked, and crucially, a database of every line of text you have ever read.

When you want to My Best Friend’s Sister clear all data, you are essentially trying to destroy this persistent file. Without deleting it, the game will always “know” you.

Where is the My Best Friend’s Sister Save File Location?

To perform a hard reset, you’ll need to locate the hidden data folders on your PC. This involves navigating to the AppData directory or the specific game folder depending on your operating system.

Navigating to the AppData Folder on Windows

On Windows, the My Best Friend’s Sister save file location is typically buried in the Roaming AppData folder. You can access this quickly using the Run command.

Press Windows Key + R on your keyboard, type the following command, and hit Enter:

Look for a folder named MyBestFriendsSister or similarly named after the developer. If you don’t see it there, check the game’s installation folder directly, often under a folder simply named game/saves.

Finding Save Files on macOS and Android

If you are playing on a Mac, the process is slightly different. Open Finder, press Cmd + Shift + G, and enter the following path:

For Android users who sideloaded the APK, you will need a file manager app. Navigate to Internal Storage > Android > data. Look for a folder usually named com.developername.mybestfriendssister. Inside, you will find a files/saves directory containing the same data structure.

Deleting Save Data on Steam Deck (Linux)

If you are playing on the Steam Deck, the file structure is different because it uses Linux (SteamOS). You cannot simply use the Windows shortcut. Instead, you need to switch to Desktop Mode and navigate to the compatibility folder.

The path usually looks like this:

You will need to find the specific Game ID for My Best Friend’s Sister (you can find this in the URL of the game’s Steam store page). Once inside, the deletion process is identical to Windows.

Which Files to Delete to Clear All Data

Once you are in the correct folder, you will see several files. Understanding which ones to delete is crucial to avoid breaking the game.

Handling Steam Cloud Saves for My Best Friend’s Sister

If you are playing on Steam, cloud storage might automatically restore the files you just deleted. This is the most common reason why a reset fails. Before you delete anything, right-click the game in your Steam Library, go to Properties > General, and uncheck “Keep games saves in the Steam Cloud”. Launch the game once to verify the reset, then you can re-enable it if desired (though it may try to upload the new “blank” state over your old one).

Can You Recover Progress Faster with My Best Friend’s Sister Cheats?

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.

Strategy: How to Speedrun Back to Your Favorite Route

After you delete save data in My Best Friend’s Sister, you are back to square one. The intro sequence might take 20 minutes to read normally. With XMOD’s “Force Skip” or “Super Speed” features, you can compress this into 30 seconds. Toggle the speed multiplier to 10x, hold the skip key, and watch the text fly until you hit the first choice menu. This turns a tedious replay into a quick setup for your new route.

Additionally, if you reset because you were broke and couldn’t afford a specific gift for the sister character, using the “Max Money” cheat immediately after a reset allows you to play the game naturally but without the financial stress, ensuring you never miss a content gate again.

Unlocking Gallery Scenes Without Replaying

The biggest pain of a hard reset is losing your gallery. If you don’t want to manually replay every route just to see the artwork you already earned, XMOD can toggle the gallery unlock states directly. This lets you keep your “completionist” status while still enjoying a fresh narrative start.

Troubleshooting: My Best Friend’s Sister Reset Progress Issues

Sometimes, even after deleting files, the game might still load your old data or crash. Here is how to fix those issues.

Fixing Corrupted Save States in My Best Friend’s Sister

If the game crashes upon loading after you’ve deleted files, it might be trying to load a “resume” state that no longer exists. To fix this, try verifying the game file integrity through your launcher (Steam/Epic), or simply reinstall the game completely. This ensures a fresh persistent file is generated correctly.

Solving Permission Errors When Deleting Files

If Windows refuses to let you delete the save folder, the game might still be running in the background. Open Task Manager and ensure the game process is fully terminated. You may also need administrator rights to modify files in the AppData directory.

Steam Cloud Conflict Resolution

If you find that your old saves keep reappearing like zombies, Steam Cloud is the culprit. The sync process can be aggressive. To permanently fix this:

1. Disable Steam Cloud for the game.
2. Delete the local files in AppData.
3. Launch the game and start a new save.
4. Close the game.
5. Re-enable Steam Cloud. When it asks about a “File Conflict,” choose to upload your Local Files to the cloud. This overwrites the old cloud backup with your new, clean slate.

Common Mistakes When You Delete Save Data in My Best Friend’s Sister

Accidentally Removing Game Assets Instead of Saves

A common error is deleting the game folder inside the installation directory instead of the saves folder. The game folder contains the actual script and images. If you delete this, the game won’t launch. Always double-check that you are in the %APPDATA% folder or specifically the saves subdirectory.

Failing to Backup My Best Friend’s Sister Saves

I cannot stress this enough: once you delete the persistent file, your gallery unlocks are gone forever unless you have a backup. Before hitting delete, simply rename the folder to saves_backup or copy it to your desktop. This gives you a safety net if you change your mind.
