Troubleshooting Tips

If your game crashes immediately, try these community-tested fixes: Troubleshooting Tips If your game crashes immediately, try

• Extract Properly: Ensure the game is fully extracted (not sitting inside a nested zip file). Joiplay needs direct access to the GameName_Data folder and the executable.
• Runtime Permissions: Go to your Android Settings > Apps > Joiplay > Permissions and ensure "Files and Media" is allowed.
• Clear Cache: Within Joiplay settings, clear the launcher cache if games stop launching after an update.

Compatibility: Which Games Actually Work?

Let's be realistic. The JoiPlay Unity Plugin is not perfect. You will not be running Subnautica or Hollow Knight on your Pixel 6. The plugin is optimized for 2D Unity games and Visual Novels built on Unity.

Performance Optimization Tips

Running Unity games on Android using a translation layer is resource-intensive. To maximize FPS:

1. Lower the resolution: In JoiPlay settings, set "Resolution Scale" to 0.75 or 0.5. Unity games look blocky but run 2x faster.
2. Disable "Wait for VSync" in the plugin options.
3. Close background apps. Unity Mono is RAM hungry. A game needing 1GB on PC needs 2GB on JoiPlay.
4. Use a phone with a Snapdragon 8 series chip. MediaTek and Exynos have poor OpenGL driver support for translation layers.

Key Features Enabled by the Plugin

1. Mono Support: Executes games compiled with Mono (the most common Unity scripting backend).
2. Input Mapping: Converts touch screen taps into mouse clicks and keyboard presses. For games requiring keyboard input, the plugin allows overlaying custom touch buttons.
3. Resolution Scaling: Forces Unity games to render at your phone’s native resolution or a scaled-down version for performance.
4. Save File Management: Allows you to locate, back up, and modify Unity game save files (often .dat or .sav) directly on your Android file system.

Troubleshooting Common Errors

Even with the plugin, errors occur. Here is your debug checklist.

Step 4: Configure Game Settings

1. Open JoiPlay.
2. Tap the "+" (Add Game) icon.
3. Navigate to your Unity game folder. Select the Game.exe file.
4. Crucially: In the "Executable" settings, ensure the "Plugin" dropdown is set to "Unity" .
5. Under "Graphics Backend," try OpenGL ES 3.0 first. If you see graphical artifacts, switch to OpenGL ES 2.0.
6. Under "Screen Orientation," lock it to Landscape if the game requires it.

Problem 4: Touch Controls Not Registering

Cause: Unity games often expect a physical mouse. Solution: In the overlay menu (swipe from left edge of screen), tap the keyboard icon. Enable "Simulate Touch as Mouse" and check "Ingame Keyboard" if the game requires typing.
