Galaxy Colosseum Topmen Can Be Pushed Online [Ro]

This code allows the topmen from Galaxy Colosseum to be pushed online, either by hitting them or boosting into them. It seems like the function that does these actions is never called online because there's a check that skips the call when online. I'm not sure exactly what the check is about, the value that it checks is loaded in an object collision function so I'll suppose it is something related to object collision types (similarly to how cataquacks continue walking in Time Trials when collided with?).
This code also makes the topmen chase other players if they hit him on your screen.

It is possible to make a code that steal an item from a random CPU/Player when using an item activator like the blooper or thundercloud?

Thunder Cloud Effect Modifier [Unnamed]

This code is the generalization of the “Mega Cloud” code from JoshuaMK. I have fixed the Item Loss bug and now you can choose the Item effect you want. If you choose Shock, POW or Blooper, then it will be like if you fired the Item when the TC zaps you.

Show Every Object on Minimap [Ro]

This code will make every object visible on the minimap as a dot, similar to how it looks like in KMP editors. You can also change the color of the dots.
You can change the color and size of the dots. I plan to work on a version where I can remove objects that aren't important (doesn't affect gameplay or are visual things like camera flashes from audience etc...) and having dot color based on the object, example, objects that damage you will be red, objects that gives you advantage will be pink and so on... Objects that move will move on the minimap and objects that can be destroyed will disappear temporarily when destroyed on the minimap.
I already released a code to force a specific object to be visible on the minimap (Show Item Boxes on Minimap https://mariokartwii.com/showthread.php?...item+boxes) but not all of them. 
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

Coin Magnet [Unnamed]

Coin Runners only


Editing KMPs to move coins (and maybe start positions) has in my eyes two disadvantages: First you have to waste time to find the correct configuration of where to put them, and second you will not be able to play normal games anymore, unless you find a way to toggle between custom track files.

This is a much easier way to do "coin KMP" now, with this code! Simply press your activator and you will attract the coins like a magnet. Of course, this is only working for free coins. Works offline and online.

NOTE: You mustn't press any other buttons when pressing your button(s) to make the code work.

Green Shell Character (Always Koopa Shell Lose Anim) [Ro]

Another silly and useless code. This code forces Koopa to do the losing animation, which is him going inside of his shell and never appearing again, thus, it looks like you're driving a green shell character. I had this idea after I had a memory of me recording that animation as a kid and pretending it was a custom character. 
You can customize  this code to affect more characters, change the desired animation or just use Force Character Animation (https://mariokartwii.com/showthread.php?tid=2208) to force every character to do a specific animation.
Second C2 hook is a fix to remove throw anim.

For context, during offline VS Races, the CPUs will drive much faster if you are in 1st place. Can somebody make a code (or provide any address/documentation) to disable & enable this at will?

I would take a quick stab at this but I can't get Dolphin to work on my main computer.

Force Character/Vehicle Color Modifier [Ro]

This code calls the N64 Sherbet Land frozen color so character/vehicle has the "white frozen color" at all times and allows you to modify the color to any of you want. If you don't use the line that modifies the color, the color will be frozen-like, very similar to "Platinum Runner". This code works for all players and in every course.
