Allow dynamic Mii name(or entire object?) when saving RKG

[malleoz]

In the headerData of generated RKG files, we can easily modify the bytes for the Mii name. It would just be a matter of determining how to retrieve the current player's Mii, or determining how exactly the user should specify what Mii to use.

We can do the entire object.

The Mii information is guaranteed to be stored in the race scenario for each player as long as the race scene is initialized (meaning we are not in a menu).

We can do the entire object.

The Mii information is guaranteed to be stored in the race scenario for each player as long as the race scene is initialized (meaning we are not in a menu).

This has proven to be hard to confirm. I've accessed multiple Mii object locations, none of which contain the full Mii data.

[vabold]

In that case I will reverse engineer the Mii group insertion.

Gecko Code was developed by Star to write raw Mii data to 0x90000020. Pasting here just in case I somehow lose it

Thus, supporting Mii names now is trivial. I will make a PR to write this info the RKG header after #41 is merged.

No NTSC-K port of Star's Mii code?

Reduced codes to remove unnecessary null checks
