This is the main event, patching AetherSX2 into NetherSX2. We’ll go step by step, keeping it clear and simple. You’ve got your files; let’s make it happen.
Step 1: Get the Permissions Right
Android needs permission to install apps outside the Play Store. Go to Settings > Apps > Special App Access > Install Unknown Apps.

UniPatcher makes patching a breeze. Open the app from your home screen.
Tap Patch File and pick your .xdelta file (like nethersx2.xdelta). It loads fast.
Next, tap Input File and select your AetherSX2 APK (4248 or 3668). UniPatcher checks if they match.
Finally, tap Output File and choose a save spot, like /Downloads/NetherSX2.apk. Hit Patch and wait a minute. Done? You’ve got a new NetherSX2 APK!
Step 4: The Final Installation
Your patched APK is ready! Find it in your file manager and tap to install.
You might see a warning about “unknown sources” or a signature issue. That’s normal for patched apps, just tap Install Anyway.
Once installed, open NetherSX2. It’ll scan for games (add your ISOs later). Congrats, you’ve patched AetherSX2 into NetherSX2!
