ROM Hack Hatsune Miku: Project Mirai DX Hacking Thread

We'll just have to use the original one.
If you still don't get it THE ONE YOU FOUND YOURSELF XD

Yeah I've been trying to figure out how that one even works xD I can change which button is which just fine, but I can't change the actual positions of the notes.

It's the "beat" value. I think it may be associated with the sample rate but I'm not sure. For example the original number is... 0025714. Change it to 0035714 it will appear later than the rest.

Hmmm, I must've been doing something wrong. The actual note positions in-game didn't change, even after hitting "Add"

Really? Gimme a sec

Did you do exactly this? I can't test right now but I did this and it worked fine.

Yep. Couldn't see any changes in game. I'll mess around with it a bit later today.

Huh. Weird... Try selecting make a backup and use the not backup, dunno why it's not working for you worked fine for me when I used it

Updated the OP with more detailed instructions. May not be 100% accurate since some of it is going by memory. Also added a few screenshots because I'm bad at wording

Is this still being worked on?

Also this may be a stupid question, but are the aet files compressed files?

finding new ways to hack this game? idunno. ask stewie1.0
this thread? idunno. ask dj505
the game? idunno. ask sega
romhacks? idunno. ask the community

its hard to crack this game because everything is a hex editing nightmare combined with misnamed files. in a while im gonna continue working on a hack im making, its not completely dead.

as for the aet files, basically all the info out there atm is in this or stewie1.0's head, so just read the thread and see what happens

I still work on this thread occasionally, but I haven't been doing much in the way of romhacks recently, mostly because I can't think of anything else to do. Also I've been caught up playing BotW, so there's that lol.

The aet files are not compressed, no. They're just multiple files that are "stacked" end-to-end.

That's cool that you still work on it, but I guess I'll try figuring out aet

Which files specifically are you trying to open? spr_ae files?

 

[YugamiSekai]

Mainly aet but I guess spr_ae too

Sorry for double post, but do you mean that each aet file is connected to each other? Or that there are multiple files in one aet file

multiple files in one. open one in a hex editor and youll see a bunch of the same header

I'm not sure about the aet files themselves, but I know for sure the spr_ae ones are multiple files in one. If you're trying to edit sprites, you'll wanna edit the spr_ae files and not the aet ones.

The files themselves aren't linked, but one single file is made of a bunch of different files, like an archive except it's not compressed and it's not a container of any kind.

Trying to figure out the animations in them, and thanks

I might learn more C File I/O and create a tool that helps with the hex editing

I started working on this a little more this morning, now that I've figured out a good setup for easy/quick file transfer to/from my PC while being able to maintian an internet connection (at school where my 3DS can't connect to the school network). I've finally got the hang of the old editor, and I'm a fair ways into making an expert chart for Senbonzakura. The only problem is that the 3DS version uses the full song, while the Project Diva F chart that I'm going off of uses a shortened version, so I'm gonna have to add some of my own notes. It won't be an exact port, but it'll be close.

Edit: For some reason, after 60 notes, the notes become invisible/off screen or something.

Edit 2: Button config was set to 0, 0, 0, 0, 0, 2000, changed it to 0, 0, 0, 0, 0, 0 and it worked again

Will you release a guide on it? I've always wanted to make a Super Hard of Romeo And Cinderella and Finder

I will when I get home, currently at school lol. It's pretty easy when you get the hang of it, and it definitely takes some trial and error. I can describe the general process tho.

Basically take the BPM of the song (in the case os Senbonzakura it's 154) and take the beat values of 2 notes. I opted for the first and second notes, which sound like 4th notes in relation to the BPM. Note 1's value is 660670, and note 2's value is 738593. Take note 2's value, subtract note 1's value, and you now have the value of a 4th note, in my case 19480.5. Divide that by 2 to get an 8th note, divide the 8th note value by 2 for a 16th note, and so on.
Say you want to add a 16th note right after the first note in the song, just take the first note's value (in this case 660670) and add the value of the 16th note to it. In this case it would look like "660670 + 19480.5", which is my 16th note value. I end up with 680150.5. Just round that up to 680151 and set that as the new note's BPM value, and done!

If you have a decimal value less than .5, round down. If it's .5 or higher, round up. The editor won't accept decomal place valules.
