"Double Dash!!" Speedometer [Sponge]

A remake of the speedometer from Mario Kart: Double Dash.

Preview:


I've aimed to make this behave and look accurate to the original game, although it's not perfect.

Stars and Bullet Bills both have unique color animations, this was inspired by CTGP-7.

File modifications are needed for this to work. A zip with assets will be provided so you can add them to your own game files.

I made this as a proof of concept. I'm certain this can be optimized in the future.

Note: This code uses addresses 0x80001610 through 0x8000161E. Ensure no other codes read or write to these addresses.

Frameskip [Wiimmfi Team]

Posted here should other people want to look at it. Extracted from v93 of the payload.

Originally wanting to convert the entire code into C2 format, I gave up due to the length and difficulty with reading the code. Some parts are in C2 whilst most parts are written in 06 format.

This only contains the actual frameskip related code. There were other parts related to debugging, but I removed them as I think it's pointless to include here and further increased the code length (It's also not even usable; Despite being downloaded and hooked by the Wiimmfi payload, a value is read that prevents the code from being executed. Another thing is that it's also similar, if not the same as the version used in CTGP to monitor performance. I would add comparison images, but I've lost this part of the code along with images of me using it.)

Technically supersedes this version as most internal systems will now run at full speed under 30 FPS with this code, but I'll post it here as I don't like the way I've converted and I don't want to port it as a result.

This code uses addresses 0x80001614 through 0x8000166B. Ensure no other codes read or write to these addresses

Anti Remote Code Execution [Wiimmfi Team]

Posted here in case other people want to take a look at it.

Patches Star's RCE exploit and several crashes related to invalid packets. There's probably more functionality but I'm not bothered to look into it.

Written in 06 format as I did not want to rewrite it in C2 Format.

EVENT Announcement Timer [MrBean]

Also referred to as "Anti-Freeze from Item Spam"

Specifies how many frames each EVENT entry is kept in the buffer when sending to players. Lower values will remove entries from the buffer sooner, allowing you to stockpile more entries without crashing.

XXXX = value in frames, it is not recommended to go above the default value of 200 frames (0xC8)

No Boundary Check [Sponge]

Also known as Disable Boundaries. You can drive in out of bounds areas without respawning.

Unlike Anarion's version, this does not cause the character to make "drowning" noises when the player does an action and does not cause the camera to have issues online.

Recommended to be paired with this code

Total No Invincibility [Fishguy, Ro]

Removes every form of invincibility in the game. You will be able to get hit while in Star, Mega and Bullet by anything that normally gives damage; items, objects, other players Star/Mega/Bullet (but you can't hit them) and more, as well as addition of some fixes and improvements to the code. Recommended to use with "No Team Invincibility" (https://mariokartwii.com/showthread.php?tid=2147).

Upside Down Player [Ro]

This code makes you (only you) upside down. The way the code was made is extremely bad and you slide a lot with it. You can only properly move and turn with "Turn in Place" (https://mariokartwii.com/showthread.php?tid=2135) and "Turn in Air" (https://mariokartwii.com/showthread.php?tid=2136).
