In the world of Pokemon game modification, there are two types of files are created, these are the IPS and the UPS files. Some Pokemon ROM hacks are created in IPS and some are in UPS file extensions. You cannot directly play any of the games on your emulator with these files, rather, you need a file patching software to make it work.
