Data Save (rksys.dat) Mapping

EDIT: 1/22/2021

Looks like all the data was copy pasted (by Atlas) to the Wiki Tockdom

Here is a very incomplete crude mapping of the Data Save.


File Size + Location
Size = 0x2BC000
Wii File System Location = /title/00010004/524d43xx/data/rksys.dat
xx values:
4a = Japan / RMCJ
4b = Korea / RMCK
45 = USA / RMCE
50 = PAL / RMCP

Loading Pointer of Data Save into a Register (for ASM Coders/Devs)
Using r3...Obviously this can only be done after the game has loaded the contents of the Data Save into memory
