rksys.dat is the name of Mario Kart Wii's save data file. It is stored in /title/00010004/524d43**/data from the Wii's NAND, where ** is the hexadecimal value for the letter that corresponds to the game's region (either RMCP, RMCE, RMCJ or RMCK).
File Format
The file has a fixed size of 0x2BC000 (or 2867200 in decimal) bytes. Each section is also fixed to specific offsets and sizes. Track arrays are ordered by a special order, which is only used in this file and in staff ghost file names.
Header
| Offset | Type | Description |

| 0x00 | String | File magic. RKSD in ASCII. |
| 0x04 | String | Unknown. Always 0006 in ASCII. Possibly a version number? |
| 0x08 | End of file header | |
RKPD
The file can contain up to 4 RKPD sections. These sections contain profile data, and are created with each new license. Each RKPD is 0x8CC0 bytes long.
| Offset | Description |
|---|---|
| 0x08 | Top left license |

Cup Data
When completing a cup, you get a gold, silver or bronze trophy and a rank (3 stars, 2 stars, 1 star, A, B, C, D, E or F). For some reason, the game seems to store some residual string data of the path of the trophy model whenever setting a new rank after completing a GP.

Time Trial Leaderboards
At the end of each time trial, a list of the top 5 times and the fastest lap are shown. The data is stored in 6 blocks, 1st to 5th and fastest lap, of 32 entries, one entry for each track. Each entry contains Mii data, the finish time and the character/vehicle combination used. The first block (rank 1) is used to show the current fastest time on the course selection screen. Each rank block is 0xC00 bytes long, each course entry is 0x60 bytes long.

Friend Data
Registered friends are stored in two blocks: the first one, the main data block, stores most of the data. The second one seems to store some flags and the PID of the friend (although this one is also stored in the main block). There are a total of 30 friend slots available.
