In the world of Pokemon rom hacking, there are two file types created, these are the IPS and UPS files. Some Pokemon ROM hacks were created in IPS while some are in UPS file extensions. You cannot directly play any of the games on your emulator using these files; rather, you need a file patching software for them to work.

Follow the tutorial below on how to use Lunar IPS Patcher for a successful Pokemon rom hack patching.
Please note that Lunar IPS patcher is a .exe file, meaning, it will work only for Windows PC, for Mac users you can use Wine to run the software.
How To Patch IPS files Using Lunar IPS Patcher
Step 1: Download Lunar IPS Patcher, extract the zip file and save on your computer.
Based on the picture in step 2, click on “Apply IPS Patch” to browse your IPS file.
If patching runs smoothly without problems, it should show a message that says “The file was successfully patched!” and if this popup message appears, it means you are all set, and you can now grab the .gba file generated from the patcher, and you’re ready to import the file to your emulator.
