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
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

So i've been working on a Mario Kart Wii mod for a while and wanted to know how to change the text of the credits. (The one with the Staff Roll B music)

I know how to change the text normally for like the menus and stuff, but not this one.

Could someone please help!

EDIT: I know StaffRoll.bmg exists, I just don't know where

Skip Ghost Selection Screen [Gabriela_]

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]

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

Any region other than NTSC-U is untested!

Three In One Item Max Probability Code [Unnamed]


This code increases the probability of getting an item of your choice to the highest value that the game allows. Also, you can change the behavior of the code by changing certain instructions. Here is an overview of the different modifications:

For the "Perfect Item Code": leave the code as it is. With this you will only get the item if it is allowed in the position for the current In-Race room size.
For the "Selective Item Max Probability": Change "2C000000" to "4C421182". This will give you the item even if it is not allowed in the position for the current In-Race room size.
For the "Positional Selective Item Max Probability": Change "2C000000" to "4C421182" and "4C421242" to "2C0C00PP". You will only get the item if you are in the position you have previously set in the code. Again, you will receive the item even if it is not allowed in the position for the current In-Race room size.

If your item is not available or you are not allowed to get it (Mega in Mega, or Triple Items in Triple Items), this address will not be called and the code will not work. Therefore it follows all item rules. In addition, I included a check of the ItemBoxSetting to make sure the code will not execute on special probability tables (like leafpiles or woodboxes).

NOTE: This code makes use of the adresses 0x8167000C to 0x8167000D. Make sure no other codes in your GCT are using those adresses.

Angry Wigglers [Ro]

This code will make the Wigglers from Maple Treeway angry  - the Wigglers will be have the angry red texture, will be blowing steam out of their nose with smoke and emitting the smoke sound effect as well. This is a visual code and will not modify Wiggler's behavior, therefore, this code is safe for legit gameplay. 
This angry effect is present in a tournament where you race the Wiggler on Wario's Gold Mine and it gets angry, thanks to the Maple Treeway Wigglers having the angry texture and particle effects present in the file, it is possible to reproduce this effect in Maple Treeway! The code ports are untested and ported by hand.

UPDATED 09/09/2023: Added missing smoke SFX

Auto Use Dodge Item When Shocked -Online- [Unnamed]


Online only.

I wanted to see how to improve Vegas Auto Attempt code and this is the outcome. Unlike his code, this code directly hooks the address that calls the shock damage on your console when another slot (not you) fires the shock and is only called once. This is the reason why the code should be completely independent of the NATNEG between clients.

Basically, the code works by delaying the shock damage (a few frames) on your console so that there is enough time to use our dodge item.

In addition to checking if you have a dodge item, this code also checks, unlike Vegas code, if you are already in star or mega state and does NOT fire a dodge item if that is the case. However, also for any moments where you normally can't use an item (i.e. during exit of cannon, spinning from getting hit by an item, etc), the code won't work.

NOTE: This code makes use of memory addresses 0x81670008 thru 0x81670009. Make sure no other codes in your GCT/Cheat-Manager are using those addresses!

## This adress normally calls the "Force Shock damage" on your console if another slot fired a shock. Therefore, it will only get called once, and should not get affected by NATNEG.
## To make the code work, we will overwrite the call and will store a frame counter to memory to let another adress call the event if a certain number is reached. That way, we delay the shock a few frames and can use our item.
## Again I repeat: The adress is ONLY called if another Slot fired the shock, it will not get called if you fire it.

## To apply the shock damage, the frame counter gets lowered every frame when shock event was triggered. And if it reaches a certain number (2), we will call the shock damage.
## In Addition, if the frame counter is equal to 4 (two frames earlier than 2), we will use our dodge item (3rd ASM).

## If the frame counter will equal 4, 2 frames before the shock damage is called, we will check if a dodge item is hold and if we are not in Mega or Star state.
## If so, the code will flip the Item usage bit and it will fire 2 frames before the shock damage is applied.

TC Given Slot Modifier & Randomizer [Vega]

For offline use only.

This code will allow you to modify who gets the TC whenever it gets passed. Therefore you can choose a slot to get the TC even if said slot wasn't participating in the pass of said TC. There are two configs of the code. 1st config is to simply set a custom slot to always get the TC. 2nd config generates the slot value randomly so you will never know who gets the TC.

X = Slot
0 = P1
1 = P2/CPU1
2 = P3/CPU2
.. ..
B = Final CPU
