In the world of Pokemon rom hacking, there are two common file types created, the IPS and UPS files. Some Pokemon ROM hacks are created in IPS, while some are in UPS file extensions. You cannot directly play any of the games on your emulator using these files; instead, you need file patching software for them to work.
If your chosen game is in IPS file extension, you need an IPS file patcher, and the popularly used tool for patching IPS files is Lunar IPS Patcher. Patching with Lunar is pretty straightforward and will take only seconds to patch a rom hack successfully.
Follow the tutorial below on how to use Lunar IPS Patcher for a successful Pokemon rom hack patching.
Please note that the 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 or use another patcher.
How To Patch IPS files Using Lunar IPS Patcher
Step 1: Download Lunar IPS Patcher, extract the zip file and save it on your computer.
Now, open Lunar IPS software, and the opened file should be the same as the image below.
Based on the picture in step 2, click on “Apply IPS Patch” to browse your IPS file.
Locate and select downloaded IPS file ROM hack and click on “Open”.
At this moment, the software will ask you to browse and select your original unmodified GBA ROM file to proceed with the patching; after locating the file, click on “Open”.
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. You can now grab the .gba file generated from the patcher, and you’re ready to import the file to your emulator.
Remember: Patching will usually fail if you recently modified the GBA ROM file. For a successful file patching, you need a clean ROM.
