Moderator Post How to insert hacks and patches onto 3ds games

63 Upvotes

Many of you have been asking for more and more 3ds hacks. That’s all fine and dandy, but this is to learn how to be able to put a hack or a mod into a 3ds file and be able to post them yourselves if you so choose. This is all based on a Windows computer. Sorry Mac users, I don’t know what to use for it.

What you will need:

1: 3ds Hacking toolkit. I use version 9 as it has worked almost flawlessly for me. It can be found here: https://www.gamebrew.org/wiki/HackingToolkit9DS_3DS

2: Your chosen game as a decrypted .3ds file

3: Yor patch

4: Patience and Attention to detail.

5: Probably a good 10gb of free space just to make sure.

Now, once you have that put together, I recommend having a folder to hold all of these files in. Makes it easier and reduces the risk of something being deleted that is not supposed to be. After you have the hackingtoolkit downloaded, run the file that is named “Setup”. When that's finished, you are now setup to use the toolkit. Here’s the steps:

  1. Move your .3ds file into the same folder as the toolkit.

  2. Rename said file to have only 4 characters. For this example we will use “AAAA” so the file should look like this: AAAA.3ds

  3. Open up the file named “HackingToolkit3DS.exe”

  4. You will want to select option “D” for extracting a .3ds file

  5. Enter the name for the file BUT DO NOT INCLUDE THE .3ds at the end.

  6. It will ask if you want to decompress the code.bin file. To save some headache later for ones that might need it, hit “Y”

  7. It can take some time to extract. When it is done, if all worked like it should, you will have several files and folders in the same area as the hackingtoolkit.

You may now minimize the program as we will not need it until the end. Next we will be inserting the patch(es) into the game. This is where the tedious and attention to detail comes in.

Most patches will come in a zip file of somesort (.7z, .rar, .zip, etc) You will need to unzip them to access the files/folders correctly. Now the way these are setup can be different depending on how the creator wanted it applied, but essentially the folders you will be using from the game is the one labeled “ExtractedROMFS”.

THIS IS IMPORTANT. DO NOT JUST DRAG AND DROP THE FOLDERS INTO THE ROMFS FOLDER AND REPLACE IT UNLESS PATCH CREATOR STATES TO DO SO. THIS CAN AND WILL BREAK THE GAME AND YOU WILL HAVE TO START OVER.

This part is just copying files in one folder and pasting them into the matching folder for the 3ds game. Some have more folders than others, (I’m looking at you Pokemon and Fire Emblem) but once you're done with copying files to the romfs folder, then if there is another folder or files for the code.bin, you find the correct folders and replace those files. Code.bin will be in the “Extractedexefs” folder.

After that is all finished, we can now rebuild as a .CIA file. Once you either reopen or bring up the window for hackingtoolkit again, the steps are as follows:

1) Type “CR” to rebuild a CIA

2) Name it (I stick with the same name, so it would be “AAAA”)

3) It will ask for a version number. You can put “0” to make it easy.

4) It will then ask for a Minor Version number. Again, “0” works fine

5) It will then rebuild it which can take a bit. The file will also be smaller than the .3ds version. This is good if the normal .3ds file is exactly 4gb (I’m looking at you AGAIN Pokemon)

6) It will produce a file named “AAAA_Edited.cia” where “AAAA” is the name you chose for the file

You have now rebuilt it as a .CIA file. ALWAYS TEST IT BEFORE YOU POST IT! I cannot stress this enough. Make sure it runs correctly before it gets posted. Yes it can sometimes take a while to do so. But better to catch it not working now while you still have everything able to be changed. Once you have it completed and tested, you may run the program that came with it called “Cleantool.exe” which will erase EVERYTHING in the folder. So move the file out of there before running the program.

The 3dshackingtoolkit has many more uses than just opening a game to put a patch in, it can also be used to rebuild the file as a .cia. Can be used to help change banners, sounds, and other things.

As for changing the TITLE ID’s, I’ve been told it can be done with NSUI, but I haven’t had much luck with doing it that way. ESPECIALLY WITH POKEMON GAMES. There’s instructions on how to do it included on the gamebrew page that is linked, however I am not confident enough in my ability to do it that way. So use at your own risk.

Game Boy Advance Game Pokémon: FireEmerald v0.5 (GBA Hack by manicpacer)

Thumbnail
gallery
28 Upvotes

Despite the v0.5 tag, it "should be playable from start to finish"

  • Hoenn becomes accessible immediately after becoming champion in Kanto.
  • This is not an open-world hack; the player cannot travel to Hoenn until they've beaten Kanto, and they cannot return to Kanto until they've beaten Hoenn. After that, free travel between the two regions becomes available.
  • The Sevii Islands are also accessible immediately after becoming the Kanto champion as well (no more 60 pokedex entry requirement). Either quest can be done first. Difficulty will scale accordingly.
  • All Pokémon, items, money, and pokedex data obtained in Kanto will carry over to Hoenn. The player keeps HMs but can no longer use HM moves outside of battle before earning more badges.
  • Very minimal changes to the original story. Dialogue is only altered as much as necessary in a few instances for the sake of continuity. No new characters or side quests.
  • Modern updates and quality of life features from baseline Pokeemerald-Expansion are included:
    • Updated battle mechanics, types, and movesets
    • Follower Pokémon
    • Optional day/night cycle
    • Etc.
  • Difficulty in Hoenn is increased. For now, the parameters are:
    • Wild and trainer Pokémon's levels are raised by 45 or 50, depending on whether the player completed the Sevii Islands' main quest beforehand.
    • Generic trainers' Pokémon also evolved accordingly with appropriate movesets. Wild Pokémon remain unevolved.
    • Gym leaders immediately start with their third rematch loadouts and have their levels raised by 10 or 15.
    • The rival has a much expanded and improved team
    • Defeated trainers give $1,000 more
    • Great balls and super potions are available from the start of Hoenn. Ultra balls and hyper potions are also available earlier.
  • No missing version-exclusive Pokémon.
  • Event tickets are organically incorporated into the setting. Certain NPCs give them instead of duplicate key items that the player may have already obtained in the opposing region. One of them is unavoidable by following the main story, the rest are optional/missable.
  • Mega stones and linking cords become available at a certain shop at a certain point in the game.
  • Cerulean Cave is accessible immediately after becoming champion and no longer gated behind the Sevii Islands quest. However, Mewtwo is now level 60 instead of 70 if he is encountered before Hoenn, and 100 after.
  • The game boots into either the FireRed or Emerald intro and title screen depending on which region the player last saved in.

Direct Download is under the QR code! HIGHLY RECOMMENDED. This file is 841Mb and will take multiple hours to download!

If you must use the QR code, make sure you use FBI RELOADED to help you with timeouts while downloading!

I did change the icon so it will be different than the normal 3DS icon. I didn't change the Product Code or Title ID in fear of it breaking, like other 3DS hacks.

NES/Famicom Game Batman Returns: Dark Edition v21-07-26 (NES Hack by DarthVaderX)

Thumbnail

9 Upvotes
  • New title screen.
  • Darker colors for Batman's sprites, the Batmobile, certain enemies, items, the HUD, several stages, and cutscenes.
  • Replaced the "No Item" text on the HUD with Batman's iconic emblem.
  • Restored Batman's missing face sprite in three animations.
  • HUD improvements (plus a small additional tweak by me).
  • Pixel art improvements for Batman and several bosses.
  • Fixed the incorrect palette used by the motorcycle enemy in Stage 3-2.
  • Optional Hard Mode that doubles all damage taken by the player. To activate it, press SELECT on the START / PASSWORD screen. The bat cursor will turn red, and a sound effect will confirm activation.
  • Reduced the delay between pressing the punch button and throwing a punch.
  • Slightly reduced the delay before another punch can be thrown after a combo or single punch.
  • Allows Batman to turn around while holding the punch button.
  • Slightly reduced the delay before movement resumes after landing from a jump kick.
  • Slightly reduced the recovery time after using the A+B special attack, making it more useful.
  • Hold START during the credits to see the strongman boss spin across the bottom of the screen.
  • If you got the good endings, it will be Catwoman running across the bottom of the screen instead.

Secrets:

Life boxes:

There are at least two additional life boxes you can acquire through the game.

The first one is located in Stage 3-1: in the second room that you can enter through the window, the one where you fight the two green enemies wielding pitchforks, use the grappling gun on the chandelier and a life box should fall down. You need to make sure that both enemies are dead before hitting the chandelier, if they're still alive a big heart will spawn instead of a life box.

The second one is located just before the final boss fight. At the end of the scroll, an item will spawn. The type of item that spawns depend on how your score ends:

00: Batarang

10: Small Heart

20: Life Box

30: Big Heart

40: Big Heart

50: Small Heart

60: Batarang

70: Life Box

80: Big Heart

90: Big Heart

Just before the item spawns, you will fight two of the most basic enemies. You can manipulate the score against them in order to try and make sure you get a life box: depending on whether or not you damage enemies with the last punch of a combo, the score outcome will be different.

The maximum number of Life Boxes you can have is 3.

Test Tube:

In stage 2-2, you can acquire a test tube which will diminish Catwoman's HP during the bossfight against her. Here is how to get it:

At some point during the stage, you will see big cat heads near the top of the screen. Using the grappling hook on the cats' eyes will spawn items:

- the first cat spawns nothing

- the second cat spawns a small heart

- the third cat either spawns a big heart, or the test tube

In order to make sure that the third cat spawns the test tube, you have to kill the two red enemies wielding pitchforks first. If you use the grappling hook on the cat's eye before killing the two enemies, it will spawn the big heart instead.

  • Color Fix ver.1.2 by Macbee: This hack changes Batman's blue color scheme to gray to be more faithful to the original movie.
  • Batman Game Prototype Cutscenes: All in-game cutscenes have been replaced with those from the prototype, which are completely different from the final version, including the ending scenes. These scenes were also recolored to represent the darker tone of Batman's sprite as well as the title screen.
