Taiko no Tatsujin - Don to Katsu no Jikuu Daibouken 3DS

Taiko no Tatsujin: Don to Katsu no Jikuu Daibouken?

(a.k.a "Taiko no Tatsujin: Don and Katsu's Spacetime Adventure" or "Taiko Drum Master: Adventures Through Time and Space") ?

So a little while ago, I was trying to get the Japanese banner for Taiko no Tatsujin: Don to Katsu no Jikuu Daibouken to show up on my US emunand. I never did manage to get that done, but instead I did get a peek at the entire filesystem for the game.

It was at that point that I realized how easy it would be to translate the game, given I had some help and had the right tools. Mostly everything was an image file, and the story text was contained in such a simple format. A close friend of mine was down to try to translate a game, and that's how this little project began.

Some people might wonder why we'd bother translating a rhythm game. Especially Taiko, which has quite the cult following in western audiences, despite the amount of Japanese used in the game. On the surface, it is a game very unwelcoming to people who have no knowledge of Japanese. Every little thing is in Japanese, with little to no English anywhere in sight.

Yet, there are still people who play and enjoy the game since the rhythm bits defy any language barrier. Our goal, however was to break that language barrier down for those of us out there who can't seem to get past it. By just translating the menu for the game, we're opening up the quirky world of Taiko no Tatsujin to an audience of players who might not have been able to experience the game otherwise.

This isn't to say that non-Japanese speaking people couldn't access Taiko before, since there was an english release back in the PS2 era, and there is the ever-popular computer game Osu! that allows people to scratch that Taiko itch. It is just that this is one of the first translation patches done on one of the Taiko console games, and to us that is pretty special.

HOW TO PATCH THE GAME:

ROMFS PATCH (FOR HANS AND MANUAL INJECTION):

First things first, obtain Taiko no Tatsujin: Don to Katsu no Jikuu Daibouken in some way shape or form. You will need either a .3DS or .CIA file to proceed from here.
- You cannot ask where to find the .3DS or .CIA file in this thread as that is against GBATemp rules. Please respect those rules.
Click HERE and follow the amazing guide provided by @Asia81 in order to obtain the necessary file you will need to apply the English patch.
The guide above will require you to DECRYPT either a .3DS or .CIA file.
The key file you will need once you decrypt and extract the rom files will be named "DecryptedROMFS.bin"
Once you have obtained the DecryptedROMFS.bin file, download the HANS patch below.
Place your DecryptedROMFS.bin in the patch directory and run the appropriate file for your operating system.
Once the patcher is finished, you will have a new file called "fullpatch v1.1_romfs.bin" in the patch directory. This is the English patched filesystem.
- For HANS users, rename this file to "00102F00.romfs" and place it in the HANS directory on your SD card. Copy over the HomeBrew Launcher custom shortcut from the HANS Patch folder to launch the game directly from your homebrew launcher of choice.
- For people who wish to rebuild their own .3DS file or .CIA file, head back to @Asia81's guide linked above to figure out how to do that. It is relatively simple.
- For more details on CIA installation, see below.

.CIA PATCH (FOR INSTALLATION OR CONVERSION TO A .3DS FILE):

First things first, obtain the Japanese, untouched CIA of Taiko no Tatsujin: Don to Katsu no Jikuu Daibouken in some way shape or form.
Download the CIA Patch from below.
Rename your CIA file to "Taiko no Tatsujin Don to Katsu no Jikuu Daibouken (JPN) (RF).cia" and place it in the patch directory. Run the appropriate file for your operating system to patch the CIA.
Once the patcher is finished, you will have a new file called "TDM_EnglishMenuPatch_v1.1.cia" in the patch directory.
IF YOU ALREADY HAVE THE JAPANESE VERSION OF THE GAME INSTALLED AND WISH TO KEEP YOUR SAVE DATA, BACK IT UP NOW USING YOUR SAVE DATA MANAGER OF CHOICE (I prefer JK's Save Manager). INSTALLING THE ENGLISH PATCHED CIA WILL REMOVE YOUR SAVE DATA. YOU HAVE BEEN WARNED.
You can now move this CIA over to your SD card and install it with your package manager of choice (BBM, DevMenu, FBI, etc.)
Once the game has finished installing, restore your backed up Save Data if you had the game installed prior to the english patch.
- In order for JK's Save Manager to restore your saved data, you need to open the game at least once so it can write the necessary data to the SD card. If you don't do this, JK's Save Manager will give you an error about not being able to read the SaveArch.

LAYEREDFS (FOR SOMEONE WHO WANTS A PURE NTR EXPERIENCE):

This is a more complicated method, but it's here if people truly want it. This is a more efficient method for me and the team, since we don't have to recompile a ROMFS file each time we want to test out something new, but like I said, it's here if anyone wants it.

Follow all the right steps highlighted in the ROMFS Patch tutorial above.
Once you have your newly translated "fullpatch v1.1_romfs.bin," you are going to want to unpack the file using the "RFSE" command while running @Asia81's HackPack.
A new window will pop up prompting you to select a .romfs/.bin file. Select the "fullpatch v1.1_romfs.bin" file and click GO to begin unpacking it.
You should then get a folder with the contents of "romfs_firstpatchrelease.bin" in it.
Download the LayeredFS plugin from below and extract it's contents to the ROOT of your SD card.
Now copy the contents of your extracted "romfs_firstpatchrelease.bin" to the "0004000000102F00" on the root of your SD card. The "0004000000102F00" folder is being seen AS the romfs file, so any small file updates can be placed there and NTR will substitute the in-game files with the files it finds within this folder.
Run NTR on your 3DS to see the changes. If you don't see anything, go back to your SD card and make sure you have the contents of your extracted ROMFS in the right place.
ALSO KEEP NOTE THAT THE LAYEREDFS PLUGIN IS ONLY FOR USERS WHO HAVE INSTALLED THE 1.20 OFFICIAL UPDATE TO THEIR GAME. You can find this update on that ISO website.

FOR DIRTY PIRATES:

I cannot guarantee this, but I am sure if you are patient enough and know how to access a certain ISO site you will be able to find both pre-patched .CIA and .3DS files. I know nothing more and nothing less about this, and it is not up for further discussion.

HOW TO APPLY PATCH UPDATES TO A PRE-PATCHED FILE:

UPGRADING FROM 1.0 TO 1.1 (CIA VERSION)

Download the "1.0 -> 1.1 (Incremental)" patch from below.
Place your version 1.0 CIA (TDM_EnglishMenuPatch.cia) in the patch directory and run the patcher.
You should get a new file called "TDM_EnglishMenuPatch_v1.1.cia
Copy the CIA file to your SD card for installation.
Before installation, BACK UP YOUR SAVE DATA using JK's Save Manager or any other preferred save data management tool.
- YOU WILL LOSE ALL DATA UPON INSTALLING THE NEW PATCH. IF YOU DON'T BACK UP AND RESTORE YOUR DATA, YOU WILL LOSE EVERYTHING. BACKUP YOUR SAVE DATA!
Once your save data is backed up, proceed to install the updated CIA with the package installer of your choice.
- FBI is recommended since it will overwrite the previous installation, unlike DevMenu, which will just spit out an error and make you uninstall the previous installation manually.
Once the new CIA has been installed, go to your home menu. You should now see the English Banner and the English title on top of the game.
- IF THE ENGLISH BANNER ISN'T SHOWING, you will have to completely delete the game before installing the new version. This way, the system will be able to refresh the icon cache and stuff, therefore displaying the new icon/banner information.

UPGRADING FROM 1.0 TO 1.1 (ROMFS VERSION)

Download the "1.0 -> 1.1 (Incremental)" patch from below.
Place your 1.0 ROMFS (romfs_firstpatchrelease.bin) in the patch directory and run the patcher.
You should get a new file called "fullpatch v1.1_romfs.bin"
- For HANS users, rename this file to "00102F00.romfs" and place it in the HANS directory on your SD card. Copy over the HomeBrew Launcher custom shortcut from the HANS Patch folder to launch the game directly from your homebrew launcher of choice.

"WHAT ABOUT THE DLC?"

The DLC is currently being worked on. There is no ETA on a patch for it, but it will be translated at some point in the near future. Please understand that the DLC takes a bit more time to translate due to it being in special file containers and whatnot.

LOADING THE DLC VIA NTR CFW:

Download the latest version of NTR CFW for your device. You'll need both the CIA launcher (from Shadowtrance) and the latest NTR.bin file. You can find these on your own. The search bar and Google are very knowledgeable!
Download the langemu_jp.plg from this post.
Download and install the DLC from wherever you manage to find it. (Hint: that iso site...)
Make a "plugins" directory on the ROOT of your SD card.
Inside /plugins/ make a directory titled "0004000000102F00".
Place the langemu_jp.plg in the /plugins/0004000000102F00/ folder.
Boot your 3DS and launch NTR CFW (assuming you installed it correctly, it will boot back to the home menu automatically).
Launch Taiko from the home menu.
Enjoy the not-yet-translated DLC songs!

LOADING THE DLC NATIVELY VIA LUMA3DS:

Oh that's right. You read that correctly. You can now load the DLC without NTR by using Luma3DS! It is a new feature introduced quite recently that is pretty damned awesome. You have @Aurora Wright and @TuxSH to thank for getting this working! This is the recommended method, as it requires little to no work on the end-users end, plus it always works, unlike NTR which can fail to boot and requires special FIRMs.

Download the latest version of Luma3DS.
Once installed (read the Wiki for instructions/help), hold SELECT while booting Luma3DS to enter the configuration menu.
Check "Enable Region/Language Emulation" in the settings menu.
Make a new folder called "locales" inside the /luma/ folder, which should be on the ROOT of your SD card.
Make a new text document and title it "0004000000102F00.txt". Inside that file, type "JPN JP". Save the text file.
Download and install the DLC from wherever you manage to find it.
Boot into Luma3DS from your entry point of choice (I personally recommend A9LH, but it isn't necessary).
Launch Taiko from the home menu.
Enjoy the not-yet-translated DLC songs!
