(Request) Gecko Code for unlocking single karts/characters, not all of them

[Zeraora]

Instead of waiting on someone to make the code, you could just edit the data save file directly (rksys.dat)

Scroll down to the unlock and stat stuff. You will see each bit flip (with byte location referenced) that unlocks each specific character and vehicle. Flip the bit high to unlock.

If you are using Dolphin, simply open up your rksys.dat file within your NAND files on your computer; Use any plain jane Hex Editor (Wii File System Location = /title/00010004/524d43xx/data/rksys.dat
xx values:
4a = Japan / RMCJ
4b = Korea / RMCK
45 = USA / RMCE
50 = PAL / RMCP)

Flip the necessary bits high for what you want unlocked. Save changes. Next time you launch your game, apply this code - https://mkwii.com/showthread.php?tid=1586 Then save your data in the game's options/settings, and after that you no longer need the code.

If you are using an actual Wii console, you can use something like WiiXplorer to dump the save file to you SD or USB, transfer that to your computer, edit the file, and place it back on your console.

This is very helpful but, He might struggle a bit because he does seem new to this type of thing. If you have any issues setting this up, respond here and I am sure someone will help.
