I'd like to know, are there gecko codes that make certain CPU(s) better/faster than t

[Sora0Pi]

This would be great if someone coul tell me!

Looks like your title got cut out at the end.

You can effect the CPU speed limit with this code - https://mariokartwii.com/showthread.php?tid=2219
You can also force the CPU difficulty with this code - https://mariokartwii.com/showthread.php?tid=2220

I mean a way to make certain cpus better/faster, CPU 1, 2, 3, 4, etc

Not sure what you want, exactly.

Does a tool like this help? - https://wiki.tockdom.com/wiki/KartAISpdParam.bin_Editor

Btw you can def edit the CPU speed limit code to enforce it based on slot (have diff limits for every CPU)

Not really, don't even have the files to use that with mods I'm trying to use it with

Try this code. It's a modification to B_squo's original code but adding in slot selectability

N = Slot 1 Soft speed limit
P = Slot 2 Soft speed limit
Q = Slot 3
R = Slot 4
.. ..
Z = Slot 11

This is good! What if I wanted to only do one or two instead of all 12, do I remove certain lines then?

This should work. Fill in any value with 00000000 to NOT have the code effect the respective slot.
