Hacking Mario Kart 8 Modding Central

[memoryman3]

Hey, so for my AI mod, I want to find the signature karts of each of the characters, so that I can implement them for the AI. Is there any way to do this?

 

[Harmonia]

I wonder how much a track BYAML tutorial is welcome at all.

- You don't want lap cheats because it can be abused.
> You can basically remove any obstacles from BYAML so it's cheating too.
> When you do just a quick look into a track BYAML, you immediately see the number of laps. If you cannot see it, you're (in all honesty) blind as frick.

I understand cheat prevention. But it just confuses me for a wanted track BYAML tutorial.
In the end, most kinds of BYAML editing will result in cheating abuse. So what's the point?

For me personally it'd be fun to mess around with adding and removing objects. I don't care about cheating.

Yeah... please make the discord invite link permanent. Thanks Also, are there any premade texture hacks for mk8 as I'm too lazy to make them myself

Sorry about that, this one is permanent:

Yeah, but as soon as a tutorial about that is up, script kiddies will cheat by then immediately knowing how to reduce lap count etc.

I haven't made a tutorial yet, but you can take a look at my repository for the editor, and the readme there should tell you everything you need to know in order to get started.

However, there's one more thing that I haven't put there yet:
Before doing opening anything, open the course BYAML you want to edit inside a hex editor, and copy bytes 0x0 to 0xF, which is usually the first row by default in hex editors.
Here's an example for Mario Stadium:

42 59 00 01 00 00 00 14 00 00 06 54 00 00 07 94

Now, make your edits. When you save your BYAML, copy that row of bytes into the new saved BYAML, at the same location. Now, it should work ingame.

A work-in-progress list of object IDs can be found here. If you are interested in contributing to it, join the Discord chat and ask Simon about it.

If anyone is curious how this differs from the master branch of MK8-Editor, I wrote instructions, fixed an issue with the loading bar, made a proper selection for BYAMLs, and added a label that shows the current object's filename. That's it for what I'll be contributing for this editor, since I actually don't know any Python. Everything I've done so far has either been guessing, or off my knowledge of doing Qt stuff with C++.

Yeah, but as soon as a tutorial about that is up, script kiddies will cheat by then immediately knowing how to reduce lap count etc.

Sorry, but I just don't agree with that logic.
"Don't tell people to hack X, they'll cheat and get banned!"
It's bound to happen, and with that logic, there won't ever be custom tracks.

With the tools that are currently available, cheating is inevitable, people will cheat. And they completely deserve to get banned.

These guides have legitimate creative purposes. We can't restrain the scene from it's full potential because of those people.

Guys!

What about choosing the AI karts?

Well I agree on that basically. Just heard that Nintendo is lazy in banning people and most Time Trials are the result of almost unnoticable hacking now.
I personally don't care much about it, I just dont wanna ruin the fun for other.s

Also, nice tools you contributed to! Think I saw them some time ago already. I'm planning on re-using my direct Blender BFRES importer for another Blender addon which allows track and object editing somewhen.

I'm afraid I never looked into that =3

(Cafiine) When I run my game it freezes on the start menu any sugestions?

The files are bad packed, or the game cannot open them. (Changing IdolA into IdolB in Splatoon freezes the game, for example)

Thnx Rudy but I already fixed it: I entered my Wii U IP but I must enter my Server IP...

If you swap N64 Toad's Turnpike course.bgenv file with another course you can make that course night time. (Still will need to change skybox)

 

[KillzXGaming]

For skybox editing. edit the course_muunt.byaml and change the obj list and the id of it to match a skybox you want to choose. Ie change it to toad's turnpike skybox. Also can change the sun as the moon. Getting the ID per object is difficult and for me i have to look in other courses and compare the course obj list and ids up.
Edit sky doesn't show up and i have no sky? Anyone with experience with model and obj swapping in courses can you help?

 

[GoldCobra]

Anyone got an idea on how to display the Timer in Online Games/VS/GrandPrix like it is shown in Time Trials?

bump.

Thanks, is there a way i could get an ID myself?
Edit: All are in data/objflow.byaml

Almost All sky IDs

Reading IDs. In data folder, convert objflow.byaml to xml.
Then search for name of obj. IDs found like this.

[Ray Koopa]

data/objflow.byaml shows you IDs to object names beyond other information. Search for a name, and the parent element tells you in the "ObjId" attribute.

There are sometimes variations (like in colors or slightly diff. objects for diff. orientations), making MgrId differ IIRC (or ObjId, too lazy to check =D).

AFAIK Obj_Obj* just creates some relation to another object and only gets active when it triggers it??
And I wouldn't be surprised if every object can be attached to a path with speed.

Dumping such a table as linked could be automated

When i open this and Splatoon´s MapInfo.byaml file with Notepad ++ appeares a lot of "icons" that say NUL, Have I decrypt it with some program?
EDIT: I see that your image isnt notepad ++, so what program is?

You need to convert the .byaml to .xml with "yamlconv", download here: https://github.com/Chadderz121/yamlconv/releases
