How To Patch IPS & UPS Files to Play ROM Hack (Free 2022 Method)

If you’ve ever played with a Gameboy Advance emulator, then you probably need ROMs. The ROMs act as cartridges, which are basically the games. A Gameboy Advance ROM has a .GBA file format. That means only one GBA emulator can play this file type, or there are some NDS emulators that can play it as well.

It’s like an MP3 player can’t play an MP4 file, or at least it only plays the audio but you can’t see the video.

This also applies to Gameboy ROMs, but there are some that come in .IPS or .UPS file format. However, regular GBA emulators cannot play these file formats.

*NEW
There is a new file format being adopted by some ROM hackers: the .bps file. This guide will show you how to patch a BPS ROM hack file.

You must know how to apply an IPS or UPS patch to these ROMs. You’ll need to follow step-by-step steps to convert an .IPS or .UPS file to a .GBA file.

What you need to do if you want to apply an IPS or UPS patch

The desired result is the conversion of the .IPS or .UPS file to a .GBA file. You cannot play the IPS or USV files; therefore patching of the file is required.

The process of patching means that we change or update the original content of the GBA file so that the content of the IPS or USV files keep the GBA format.

In order for this to happen we need a few things.

Things needed for patching a ROM hack

  • patch file
  • ROM base
  • patcher application

The first thing you need is the .IPS or .UPS patch file. You need them because they are the games you want to play. For Pokemon games, the ROM hacks change the content of the game.

Next you need the base ROM or the ROM the hack is based on. For example, a ROM hack Pokemon Gaia uses FireRed as its base game.

Third, you need the patcher, i. H. the app or program you use to apply an IPS or UPS patch. The gist of this is that we’re patching an actual Pokemon ROM into a ROM hack or whatever the contents of the IPS or UPS file is.

Finally, always make sure you have a separate copy of the original Pokemon game ROM because once the patch is ready, all contents of that ROM will be modified and gone forever.

Why the patch can fail

  • There are several reasons and the first one is that the IPS or USV file is unreliable to begin with. In short, it’s not a good copy or it just wasn’t programmed properly.
  • The second reason is that you are not using the right base game. You’re probably using Pokemon FireRed as your base game, but it actually needs Emerald.
  • Your copy of the base game is not reliable. There are ROMs out there and not just Pokemon that might have been corrupted or not suitable for patching .IPS or .UPS format.
  • The patcher is not good and unreliable. Don’t worry, we will include reliable patchers in the step-by-step guide.

If you want to progress then by all means try to patch the ROM files you have so you can play them on your GBA emulator.
