How to Transfer JoiPlay Save Files Between Devices (Complete 2026 Guide)
Switching between PC and Android shouldn’t mean losing your progress. If you’ve put hours into an RPG Maker game or a RenPy visual novel and want to keep playing on your phone through JoiPlay, the good news is you don’t have to start over. JoiPlay supports cross-platform save files for almost every engine it runs. Copy the right files to the right folder, and your PC progress carries straight over to Android, or from one Android device to another.
Here’s exactly how to do it for RPG Maker XP, VX, VX Ace, MV, MZ, and RenPy games, step by step.
Why JoiPlay Save File Transfer Works
Before jumping into the steps, let’s quickly understand WHY this works.
JoiPlay is not a traditional emulator, it’s a game interpreter. This means it runs the actual game code directly on Android. Because of this, the save files created by JoiPlay are in the exact same format as the save files created by the PC version of the same game. This is what makes save file transfer possible, and it works both ways:
- ✅ PC → Android: Transfer your PC save to continue on JoiPlay
- ✅ Android → PC: Transfer your JoiPlay save to continue on PC
- ✅ Android → Android: Move saves between two Android devices
- ✅ Old JoiPlay → New JoiPlay: Transfer saves after reinstalling the app
What You Need Before Starting
Make sure you have everything ready before attempting a save file transfer:
On your Android device:
- ✅ JoiPlay app installed (latest version)
- ✅ Correct JoiPlay plugin installed for your game type
- ✅ The complete game folder already set up in JoiPlay
- ✅ A file manager app (most Android phones have one built in)
On your PC:
- ✅ The game installed and working
- ✅ A USB cable OR access to Google Drive/cloud storage
- ✅ Your PC save files (we’ll show you where to find them!)
Transfer method options:
- 📱 USB cable: Fastest and most reliable
- ☁️ Google Drive: Easy wireless transfer
- 📧 Email: Quick for small save files

Where Are JoiPlay Save Files Located?
This is the most important thing to know. Save files are stored inside the game’s folder on your Android device.
Finding Save Files on Android (JoiPlay)
Save files are located here:
- Internal storage→ (your game Folder) → Save
For example if your game is called “HeroQuest” and you saved it in your Downloads folder:
- Internal Storage\Downloads\HeroQuest/Save
The actual save file names vary by game type:
| Game Type | Save File Format | Example |
|---|---|---|
| RPG Maker XP | .rxdata | Save01.rxdata |
| RPG Maker VX | .rvdata | Save01.rvdata |
| RPG Maker VX Ace | .rvdata2 | Save01.rvdata2 |
| RPG Maker MV | .rpgsave | file1.rpgsave |
| RPG Maker MZ | .rmmzsave | file1.rmmzsave |
| RenPy games | .save | 1-LT1.save |
Finding Save Files on PC
On PC, save files are almost always in the game’s main folder under a Save or www/save subdirectory:
RPG Maker XP, VX, VX Ace:
- C:\Users\[YourName]\[GameFolder]\Save
RPG Maker MV and MZ:
- [GameFolder]\www\Save
RenPy games:
- C:\Users\[YourName]\AppData\Roaming\RenPy\[GameName]
Method 1: Transfer Save Files Using USB Cable (Recommended)
This is the fastest and most reliable method. No internet required!
PC Save → JoiPlay Android
Step 1: Find your PC save files Navigate to your game’s Save folder on your PC and locate your save files (check the table above for the correct format).
Step 2: Connect your Android to PC
- Connect your Android phone to your PC using a USB cable
- On your phone tap “File Transfer” or “MTP” when the USB connection prompt appears
- Your phone will appear as a drive in Windows Explorer
Step 3: Navigate to your game folder on Android In Windows Explorer open your phone’s storage:
- This PC
→[Your Phone Name]→Internal Storage→[Game Folder]→Save
Step 4: Copy the save files Copy your PC save files and paste them into the Save folder on your Android device. Replace any existing files if prompted.
Step 5: Launch the game in JoiPlay Open JoiPlay, launch your game, and load your save. Your PC progress should be right there waiting for you! ✅
JoiPlay Android Save → PC
This works exactly in reverse:
Step 1: Connect Android to PC via USB Step 2: Navigate to your game’s Save folder on your Android device Step 3: Copy the .rvdata2, .rpgsave, or relevant save files Step 4: Paste them into the Save folder of the same game on your PC Step 5: Launch the game on PC and load your save ✅
How to Confirm a Save Transfer Actually Worked
Before closing JoiPlay and assuming everything’s fine, take a moment to confirm the transfer succeeded:
- Check the file size matches. Compare the save file’s size on your Android device against the original on PC. A save file that’s significantly smaller (or 0 KB) usually means the copy was interrupted.
- Load the save immediately. Don’t wait until your next session, open the game right after transferring and load the save to confirm it appears and loads correctly.
- Check the in-game timestamp or playtime. Most RPG Maker and RenPy games display a save timestamp or total playtime on the load screen. Confirm it matches your PC progress rather than showing an old or blank save.
- Keep the original file until confirmed. Don’t delete your PC save file until you’ve verified the Android version loads correctly. If something goes wrong, you’ll want the original to try again.
Method 2: Transfer Save Files Using Google Drive (Wireless)
No USB cable? No problem! Google Drive makes wireless save file transfer super easy.
Step 1: Upload Save File from PC to Google Drive
- Find your save files on PC (see locations above)
- Go to drive.google.com
- Upload your save file(s) to Google Drive
- Wait for upload to complete
Step 2: Download on Android
- Open Google Drive app on your Android phone
- Find your uploaded save file
- Tap the three dots next to it
- Tap “Download”
- Note where the file downloads to (usually Downloads folder)
Step 3: Move Save File to Game Folder
- Open your File Manager app
- Navigate to your Downloads folder
- Find the downloaded save file
- Cut (not copy) the file
- Navigate to your game’s Save folder:
- Internal Storage → [Game Folder] →Save
- Paste the file there ✅
Step 4: Launch JoiPlay
Open JoiPlay, launch your game, and load your transferred save!

For a more automated approach, you can use Android backup apps that let you schedule regular backups of specific folders, perfect for protecting your JoiPlay save files!
Game-Specific Save Transfer Tips
Different game engines have slightly different quirks when it comes to save files. Here are some specific tips:
RPG Maker MV and MZ Games
Save files for these games are stored in the www/save folder inside your game directory. They use .rpgsave (MV) or .rmmzsave (MZ) format and are actually JSON files, which means they’re text-based and easy to read and edit if needed!
When transferring:
- PC location: [Game Folder]\www\save\file1.rpgsave
- Android location: [Game Folder]\www\save\file1.rpgsave
Make sure the folder structure matches exactly!
RPG Maker VX Ace Games
VX Ace saves use .rvdata2 format. These are stored directly in the game’s root Save folder:
- PC: [Game Folder]\save\save01.rvdata2
- Android: [Game Folder]\save\save01.rvdata2
RenPy Visual Novel Games
RenPy save files are slightly trickier because on PC they’re stored in a hidden AppData folder rather than the game folder itself. On Android however, JoiPlay stores them inside the game folder.
PC location:
- C:\Users\[Name]\AppData\Roaming\RenPy\[GameName]\
Android location (JoiPlay):
- [GameFoler]\game\saves
To transfer from PC to Android:
- Find your saves in the AppData folder
- Copy the
.saveand.jsonfiles - Paste them into the game/saves folder on Android ✅
Pokemon Fan Games (RPG Maker XP)
Pokemon fan games use .rxdata save files. Transfer works perfectly, just copy the Save folder contents between PC and Android. Your Pokemon, items, badges and story progress will all carry over. If you want to learn how to play Pokemon games on Joiplay, we have a proper guide on it.
Troubleshooting Save File Transfer Issues
Having problems with your save transfer? Here are the most common issues and fixes:
❌ Save file doesn’t appear in game
Check that you placed the save file in the exact correct folder. The folder structure must match perfectly, even one misplaced folder will cause the game not to find the save.
❌ Game crashes when loading transferred save
This usually means the save file is from a different version of the game than what you have installed. Make sure both your PC and Android versions of the game are the same version number.
❌ Save file shows but progress is wrong
Double check you copied the right save slot file. Most RPG Maker games have multiple save slots (Save01, Save02, Save03 etc.), make sure you copied the correct one!
❌ RenPy save shows “incompatible save”
RenPy saves can become incompatible if the game version changed significantly. Try loading an earlier save file, or check if the game developer released a save migration tool.
❌ Can’t find the Save folder on Android
Make sure JoiPlay has storage permission enabled. Go to Settings → Apps → JoiPlay → Permissions → Enable Storage. Also make sure you’ve launched the game at least once in JoiPlay before trying to find the Save folder, JoiPlay creates the folder structure when the game first runs!
❌ File Manager can’t see game folders
Some Android file managers hide certain folders. Try enabling “Show Hidden Files” in your file manager settings, or use a third party file manager like MiXplorer or Solid Explorer which show all files.
Recovering from a Corrupted or Failed Save Transfer
If a save file becomes corrupted during transfer, or a game crashes and refuses to load a specific save afterward, a few recovery options are worth trying before giving up on that save:
Try an earlier save slot. If you regularly save to multiple slots (which is worth doing for exactly this reason), loading the second-most-recent save often works even when the latest one is damaged.
Re-transfer the file from the original source. If your PC save file is still intact, delete the corrupted copy on Android and re-copy the file fresh, sometimes a partial or interrupted transfer is the actual cause rather than the save itself being bad.
Check for a backup copy. If you followed the Google Drive backup habit covered earlier in this guide, your uploaded copy is likely unaffected even if the local Android copy became corrupted.
For RenPy specifically, corrupted saves sometimes still open partially, showing a “rollback” option that lets you step backward to an earlier point in that same save rather than losing all progress from that file.
Pro Tips for Managing JoiPlay Save Files
💡 Tip 1: Name your save slots clearly In games that allow custom save names, use descriptive names like “Before Boss Fight” or “Chapter 3 Complete” so you always know what each save contains.
💡 Tip 2: Back up saves before using cheats If you plan to use the JoiPlay cheat menu, always back up your save file first! Cheats can sometimes cause unexpected behavior and having a backup means you can always go back.
💡 Tip 3: Use Google Drive as your save cloud Set up a dedicated “JoiPlay Saves” folder in Google Drive and make it a habit to upload your save files there after every major gaming session. It takes 30 seconds and protects months of progress!
💡 Tip 4: Keep PC and Android versions in sync If you play the same game on both PC and JoiPlay, make it a habit to sync your saves regularly. Decide which version is your “main” and always transfer the most recent save before switching devices.
💡 Tip 5: Check game version numbers Before transferring saves, confirm both your PC and Android game installs are the same version. Transferring saves between different game versions can cause corruption.
Conclusion
Transferring save files on JoiPlay is one of the most useful things you can learn as a mobile RPG gamer. Once you know where your save files are and how to move them, switching between PC and Android becomes completely seamless. Now go pick up that epic RPG adventure exactly where you left off, on whichever device you like. 🎮
