If you ever played a Gameboy Advance emulator, then chances are you will need ROMs. The ROMs will act as the cartridges, which are basically the games.
A Gameboy Advance ROM will have a .GBA file format. This means that only a GBA emulator can run this type of file, or there are some NDS emulators that can run it as well.
It is like an MP3 player can’t play an MP4 file, or at least only the audio will play, but you can’t see the video.
That is the same for Gameboy ROMs, but there are those that come in a .IPS or .UPS file format. However, regular GBA emulators cannot play these file formats.
What you need to do is to know how to apply an IPS or UPS patch to these ROMs. What happens is that you need to do a step-by-step procedure to transform a .IPS or .UPS into a .GBA file.
*NEW
There’s a new file format that some rom hackers are now adapting, it is a .bps file. Check this guide to learn How To Patch A BPS ROM Hack File.

What you need to do if you want to apply an IPS or UPS patch
The outcome that we want is to change the .IPS or .UPS into a .GBA. You can’t play the .IPS or .UPS files; hence patching the file is needed.
The process of patching means that we change or update the original content of the .GBA file to have the contents of the .IPS or .UPS files will be keeping the .GBA format.
In order for that to happen, we need a couple of things.
Things Needed for Patching a ROM hack
- Patch file
- ROM base
- Patcher app
The first thing that you need would be the .IPS or .UPS patch file. You’ll need those because they are the games you want to play. With Pokemon games, the ROM hacks will change the game’s content.
The next thing you need is the base ROM or the ROM on which the hack was based. For example, a ROM hack Pokemon Gaia uses FireRed as its base game.
The third thing you’ll need is the patcher which is the app or program that you will use to apply an IPS or UPS patch. The gist of this is that we will patch an actual Pokemon ROM into a ROM hack or whatever the contents are inside the .IPS or .UPS file.
Finally, always make sure you have a separate copy of the original Pokemon game ROM because once the patch is finished, all the contents of that ROM will be changed and gone forever.
Why the patch would fail
- Outdated or unreliable patch file – There are several reasons, and the first one is that the .IPS or .UPS file from the start is unreliable. In short, it isn’t a good copy or it just wasn’t programmed correctly.
- Using wrong base rom – Another possible reason is that you’re not using the right base game. You’re probably using Pokemon FireRed as the base game but it actually needs Emerald.
- Corrupted or used base rom – Your copy of the base game isn’t reliable. There are ROMs out there that may have been corrupted or isn’t suited for patching the .IPS or .UPS format.
- Unreliable or outdated patcher – The patcher is not good and unreliable. Don’t worry, we’ll be including reliable patchers in the step-by-step procedures.
- Wrong base ROM version – Your ROM base might not be compatible with the rom hack game. Some ROM hacks require a specific base rom version. For example; Pokemon Scorched Silver v1.3 requires a clean Pokemon Emerald rom, Emerald (U) (TrashMan).
How to Patch a .IPS file using Lunar IPS (Works for Windows PC’s)
In this procedure, we will guide you on how to apply a .IPS patch. The patcher we will use is Lunar IPS. This patcher will only work on .IPS formats.
We will also use the Rocket Edition Final v1 as our .IPS file which we will patch with FireRed as the base game.
Step 1: Lunar IPS patcher
Lunar IPS patcher. Be careful when ing the file from other sources, romhacking is the official source of Lunar IPS Patcher.
Step 2: Launch

Step 3: Browse your IPS file

Step 4: Select the base game
You will then click on the base game which is FireRed in this tutorial.
Step 5: Patching Starts
The patch will automatically begin, which usually takes a couple of seconds.
Step 6: Rename ROM Hack file
This step is optional, but it’s a good idea to rename your newly patched FireRed ROM to something like Rocket Edition Final v1 or any name you prefer.
Renaming it helps you easily identify your ROM hack, especially when you have multiple hacks in your collection.
Step 7: Launch the game
Open your GBA emulator, and if the game loads and runs Rocket Edition properly, then everything was done correctly.

Conclusion
Now that you know how patch IPS and UPS files to play a Rom hack, you can use any of the three methods above based on what you need.
that the patcher you use will only patch specific to the ROM’s file type whether it is a .IPS or .UPS one. In some cases, you don’t have to a GBA ROM file with a .IPS or .UPS format.
If you look hard enough, you may find an actual ROM with a .GBA format of the ROM hack that you want. Most of the time, these files are available if the ROM hack is currently having an update or patch being made for it.
If you want to get ahead, then by all means try to patch the ROM files that you have so you can play them on your GBA emulator.
I try to apply the patch – if it matters, i put a pokemon emerald rom in ‘file to patch’ as instructed and put emerald thera ex ups file in ups patch but it says “the patch doesn’t match the file, patching canceled.” is this because the pokemon emerald rom file is a gba file and not also a ups file? what do i do?
The emerald ROM must be a .gba file format, better check the video Reply
Hi, I am trying to apply the patch it is compatible and I click on “Apply Patch” only nothing happens my page gets refreshed doing this from an iPhone and I tried multiple different browsers to see if it works but with no luck.
Hi there, Appie. Make sure your ROM base version matches the patch file that your ROM hack needs. For example, if a ROM hack requires a Squirrels version ROM base, then you must use a Squirrels version to patch the game successfully.

I have a question. Is there an easier way to update the rom hacks to the newer versions of themselves without having to patch?
Hello Jared, each rom hack typically comes with its own set of instructions for updating, usually provided by the author. However, I haven’t come across any information on how to simplify these instructions.

Hi there Phoenix. Infinite fusion is made with RPG Maker or Essentials. Therefore patching is not required to play the game. Install the game directly on your Windows PC, almost like a normal software installation. If you wish to play it on Android, see our guide on Reply

Hey Ashley, thanks for coming here. First off, Radical red is a FireRed rom. So you need to find and use a clean FireRed rom for patching, preferably the older version, which is V1.0 that most rom hacks require for patching. You can also watch this video on how to patch rom hacks with NUPS Reply

I have ups file of pokemon unbound so I did as told in the video but it says “the patch doesn’t match the file” (the file I selected was fire red I am pretty sure that’s the one the game’s based on)
Which FireRed rom version do you have? Cuz most rom hacks require V1.0 and may not work for V1.1.
Where did you find the .gba format file for Firered? Ive been looking everywherw but cant find one.
Hi there, sorry but we don’t give out information related to roms here.
gameboy-advance/pokemon-fire-red-version
The patcher doesn’t look like the picture when I it so I don’t know how to do it with the new interface.
When I patch it together and start the it becomes a .txt file instead of gba. How would I fix this?
What would you recommend if I’m using an HP laptop?
Either of the mentioned methods works with your HP laptop.
I ed the latest GS Chronicles and played it to the point where my guys are level 16 and evolving but as soon as any of them evolve it crashes my game. I have seen several people ask this question but with no response. How do you fix this problem?
Could be a bug in the game? Or try switching to another emulator. I recommend using VBA for Windows or MyBoy for Android.
When i tried to do FireRed.gba and FireRed Radical ups that came from ur website, It says the patch is corrupt. What do i do? Get another version of FireRed or get a new ups?

For Mac s, you can go with ROM Patcher JS which is the third tutorial in this guide. But you can also you the tool called Multipatch. I’m updating this article to include a tutorial for Multipatch.

Trying to patch Pokemon XD to XG new gen an says the patch doesnt match the game file
how do i fix this problem
Hello. First, I want to say your articles are awesome. I’ve just recently gotten into pokemon ROMs and they have been a huge help. I’ve been going through this article in conjunction with your article about the best pokemon ROMs 2021 to get a good collection. So far, everything is working – i just am wondering, normally with my emulator (VBA) the version of Fire Red i play is a .zip file. With these methods, the games aren’t .zip, but .gba. Do I have to be careful If i plan on using both .zip and .gba with my emulator, or is it ok to switch between them for different games as long as it’s all working?
Hey there Nick, thanks for coming here. There shouldn’t be a problem if you’ll use .zip or .gba. But my suggestion is to put that file in a folder separate from other games you have.
hey, i imagine my issue is an easy fix and im just struggling because ive never been good with files and coding and the like. im trying to patch pokemon saiph to firered, however when i go to patch them nups says that theres an error opening the firered file. i can open the firered file fine on my emulator, so im not sure why its having issues opening if it can run as is. again, probably a really easy thing to fix, sorry if im asking the obvious or its a silly mistake, i really struggle with anything even remotely behind the scenes in computers and just patching them together period feels so out of my depth
I click on the fire red gba file, then go to try to patch it to pokemon gaia but it says file does not math. Any solution?
match*
Make sure the game is in .gba file format and not in .zip. Also, you might need a v1.0 FireRed rom version instead of v1.1.
I had the same problem as ZeroD and ing v1.0 instead fixed it instantly. Thanks!
I’m glad my suggestion helps and yes, cheats can work only on V1.0 and not on v1.1
Why i can’t save the game? I am saving the game and im closing the program.. once i open it it brings me back to new game..
Thanks in advance!
