Hey GBATemp users! Today i gonna show you one trick you can do on MHXX. Since you have a Jukebox on the Hunter's Tavern, i was wondering if i can add my own playlist and listen my own songs, so i decide to try this with success and im gonna share you the method i used. I think MH OST is pretty good, but damn, when i put all my favourite game's songs, the waiting time now is just GREAT!

First of all i want to say a very big Thank You to dasding, for his great job on 3DS scene and recent work, also all tools used in this tutorial are made by him.
So here we go!

What we need?
-CFW on your 3DS with SD Card
-MH Mod Tools
-NTR CFW or MHXX Eng UI Patch

1. Getting your .WAV songs
So you need to know what songs you want to include in the playlist. You can use songs from your PC or you can do a very easy and quick job using this tool, so you can directly grab the wav files from youtube (change output from mp3 to wav). I recomend take the best quality songs, because some of them are too loud when played on 3Ds. You need your files on .wav files, no matter PCM / KBPs, so do your job and get your loved music!


2. Convert .WAV into .MCA
Now we need MH Mod Tools. Check the topic before complain about the installation, all information you need is in the What we need section. When you are ready, you need to find a file named

3_wav2mca_mhx.bat
​

You need to drag and drop your .wav files to this .bat file, then a new CMD screen will appear, showing up the conversion progress, it will auto-close when done. If you are getting problems using the drag and drop method, you just need to right click on the .bat and press Edit. Then put your "filename.mca" after the %1, just something like this:

tools\wav2dsp.exe %~1 filename.wav
c:\python27\python.exe tools/mcatool.py --mhx %~1 filename.wav
del *.dsp​

Now you should have your .MCA files in the same folder, repeat the job with the rest of your songs.

UPDATE: Having problems with bad quality .mca / strange sounds? Check THIS <

3. Get the XX Eng Patch or NTR
We need the NTR plugin in order to do this, so i highly recommend use this with the great MHXX Eng UI Patch, so in this step you just need to install the patch using NTR methods, not CIA Patch methods. Check the What we need section, is very simple. When you get the patch working proceed to the next step.

4. Moving files to SD
Put your SD card on PC, then look for the path (X should be your drive letter)

X:/mhxx/​

Now you need to create some new folders. The final path should be like this:

X:/mhxx/sound/bgm/map/v07/wav/​

Total songs you can add to your playlist is 13. You need to place in this wav folder your .MCA song files.
Now you need to rename your files to this:

bgm_v07_01.mca
bgm_v07_02.mca
bgm_v07_03.mca
bgm_v07_04.mca
bgm_v07_05.mca
bgm_v07_06.mca
bgm_v07_07.mca
bgm_v07_08.mca
bgm_v07_09.mca
bgm_v07_10.mca
bgm_v07_11.mca
bgm_v07_12.mca
bgm_v07_13.mca​

Im not sure if you got all 13 songs unlocked from the beggining, so i strongly recommend start renaming your files starting from 1 and go on, because maybe you cant listen the last songs if you havent unlocked them yet.

Also if you want to change the Intro song, just create this path

X:/mhxx/sound/bgm/title/wav/​

and place your song here with name:

bgm_title.mca​

5. Enjoy!
Just start the patch by opening NTR CFW. Then go to MHXX and travel to the new Hunters Tavern. Speak with the girl next to the guy who gives you the quests, and check if all is working fine.
So now you can go and spam the dance emote while hearing your favorite songs
