ROM Hack Hatsune Miku: Project Mirai DX Hacking Thread

Ok, cool! There's pretty much zero coding involved, it's mainly just using existing things to modify files. Since they're all Nintendo or Sega specific formats, it's tough, but for most of them there are already programs to assist with modification. Most of it is designing new sprites/editing charts, not a lot else to do.

The editor isn't the easiest thing to use, but it works (takes some trial and error sometimes). It requires math to use, just basic addition/subtraction to figure out the placement of notes, but that's about it. Not super intuitive but it's there

Sweet, if you want to work together on adding a song PM me and ill send contact info

Alright, I'll keep that in mind! Right now it's just small side projects like adding Super Hard modes to songs (got to the middle of Senbonzakura before I encountered a glitch that makes it unplayable) but later on I'll probably start doing songs from scratch haha

I reserve the dibs on to be modded first

Ok lol. The first song I do is probably gonna be Setsuna Trip, since it matches the BPM of some other songs so the best offset is super easy to find. Plus it's a good song.

Also, forgot to mention, the time limit for custom songs is gonna be around 3:20 because there's only one song in the game that has a chart that's one continuous stream without breaking (1925 to be specific). All other songs have breaks that you can't insert notes in unless you figure out how to create your own longer .dsc file.

Gotta figure out how to make a completely new track instead of replacing it. Seams like a must in the long term especially if we are adding multiple tracks

Definitely. I imagine it shouldn't be too hard, especially since it's been confirmed possible... I think the person who found it is Stewie1.0 here on GBATemp

Sorry for double posting, but I have an announcement.

The Project Mirai DX: Matryoshka Edition project now has a GitHub page! This is meant to make it much easier for anyone who wants to contribute to the pack by making it possible to create a fork of the main project, add your own stuff, and merge it back to the main repository.

Awesome! Any chance I could include the chart in the Project Mirai: Matryoshka Edition romhack? (Full credit to you of course)

On a side note, have you encountered any bugs in the dsc file? I've been working on an expert mode for Senbonzakura but I find the chart just cuts off and ends halfway through, weird bugs like that

Ok, you can include it

Yes, it was not loaded, or long press was interrupted halfway…

Ok, thanks!

I'm not sure what causes these issues in the .dsc files, it's weird. One of the issues I found is even after deleting every single note in a file, there are 2 or 3 random notes throughout the song anyway even though there shouldn't be, or sometimes notes just don't show up

Perhaps the random notes may be erased, but I do not know the cause at all.

I will only say where I can understand dsc ButtonConfig

0, 0, 0, 0, 0, 0
1, 2, 3, 4, 5, 6

1: double note
-1000 on the left side
1000 to the right(Or inside, outside, Should also verify this)
2:SP note
SP start at 1000
SP ends at 2000
3:Spin bonus
Enter 1000 for start and end
4:Create space(?)
Even if there are notes there, it will be blank(Enter 20)
5:?
(No Logic can not confirm it)
6:note display position(?)
Or line start position(?)

Next I would like to create Kimi no Taion(It may not be created…)

I'm sorry I am not good at English.really sorry…
(Also, Leia of Mirai 1 can play on Mirai 1, You can also change it with dsc editor, The dsc button config of Mirai 1 is different from the dsc button config of Mirai DX.)

Has anyone else tried adding models in the game? I’m trying to add Kasane Teto’s hair, but I get an error every time.

I know it's possible, I just haven't had success with it... Iirc the number of faces in the now model must match the old one or something like that

Is there a way to export stages and some models with correct UV? Whenever i try to export it the uv of the stage is assigned to the shadowmap instead of the actual textures

How to get the mirai files if they are in .3ds format or .cia format?

You'll need something like HackingToolkit3DS to extract the files, which is fairly straightforward. From there you can edit the files in the DecryptedRomFS folder and stuff then either repack it and install or use the files with LayeredFS

Any updates? Really was excited to play some new songs!!

Nothing I know of, unfortunately :/ It's still possible to make song charts and stuff but I'm not sure if there are many finished charts released publicly

I've just been trying to update my SAve Editor and nothing else. I haven't even bothered with trying to chart my own songs.

 

[DoJo_Master]

I found this, still confused on how to install the patch though haha

Looks very impressive!
