Online BRSTM/BCSTM/BFSTM Maker

Online BRSTM/BCSTM/BFSTM Maker

Link: https://kazuki-4ys.github.io/web_apps/mu-wave/

Author: Kazuki

This web page was created on 2022/03/10 as my WebAssembly study.
It is multi-track compatible and can even set loop points while playing back on the fly.
Just recently updated to support BCSTM!
Because it uses WebAssembly, it creates BRSTM/BCSTM/BFSTM faster than BrawlBox/Create, even though it is a web app that runs client-based.
wav, mp3, and ogg are supported as source audio files.

Replace Cow Walk Animation with Unused Run Animation [Ro]

Posted by: _Ro - 09-10-2023, 01:20 AM - Forum: Visual & Sound Effects - No Replies

	Replace Cow Walk Animation with Unused Run Animation [Ro] Silly and useless code, all it does is it replaces the cow walking animation with the unused running animation, seeing in pre-release videos of the game.

Load Disabled Course Objects [Ro]

Posted by: _Ro - 09-09-2023, 11:20 PM - Forum: Offline Non-Item - No Replies

Load Disabled Course Objects [Ro]

This code will load "disabled" course objects.
The course.kmp file (which stores many of the course's specific parameters, such as object placement) has a presence value defined for every object to determine in which instances it should load (for example, should it load in every mode, only on single player and not multiplayer, etc). Certain objects have this value set to 0x00 which disables the object, preventing it to appear in-game and thus going unused. This code makes it so these objects are loaded.
For reference, here's a list of disabled objects: https://tcrf.net/Mario_Kart_Wii/Unused_Course_Elements

Fix for BRSTM with Fewer Audio Tracks [stebler]

Posted by: Kazuki - 09-08-2023, 10:01 PM - Forum: Visual & Sound Effects - No Replies

Fix for BRSTM with Fewer Audio Tracks [stebler]

This code prevents the bgm from stopping due to the low number of tracks in BRSTM.

Original code was written by stebler as a part of mkw-sp.

I ported it to gecko code.

It is recommended to use with this code.

NTSC-K is not tested.

Blueshell behavior request + existing Code

Posted by: daerup - 08-20-2023, 08:43 PM - Forum: Code Support / Help / Requests - No Replies

Hi,
I am curious to know if there is a code available that alters the behavior of the blueshell in such a way that, when thrown by the leading player (1st place), it targets the second-ranking player instead of the thrower. So with this Code, you cant blue yourself any longer. I think this would be really fun for offline play with friends Big Grin
Does this or something similar already exist?

On a another note, I recall seeing a code that caused a player who was hit by a shock to get squished when bumped by someone who is normally sized (like when getting bumped by a mega), same as it has been in Mario Kart 64.
I cant for the live of me find this anywhere and I am starting to question if it even exists lol.

Does somebody have this code?

Thanks for your time.
Kind regards

Daerup

Considering most distributions don't support ghosts that screen becomes unnecessary for them. This code skips the screen and just shows start game confirmation instead.

Show Item Boxes on Minimap [Ro]

Posted by: _Ro - 08-04-2023, 08:19 PM - Forum: Visual & Sound Effects - No Replies

Show Item Boxes on Minimap [Ro]

This code will show item boxes on minimap as a dot. If an item box is destroyed, the icon will disappear until the item box respawns. You can also choose what color the icon will be. Unfortunately, there are two catches to this code: It will not affect moving item boxes (can only target one object at time, to be worked on a future version of the code) and the other one is that you MUST use the "Show Battle Map Icons" code by CLF78 (I did not include it in my code to not take any credits and to make sure people are aware of his code. "Show Battle Map Icons" code by CLF78: https://mariokartwii.com/showthread.php?tid=1840

This code can be modified to target any object of choice, this includes moving objects: Icons of the moving object will move on the minimap. It is possible that I will work on a v2 of this code where it affects all item boxes (both stationary and moving boxes) - 80887CDC call NTSC-U for reference
