Filesystem/rel/StaticR.rel

From Custom Mario Kart
Jump to navigation Jump to search

The file StaticR.rel is the only file in directory /rel and contains much data for the Mario Kart Wii. All 4 known versions (PAL, NTSC, NTSC/J and KOREA) differ in size and content. All data is stored as big endian values. It is very hard to find things in StaticR.rel, because it seems to be an exported data section of a dol: It has no structure but the related dol knows where the data is stored.


Track Order Tables

There are 5 copies of the track assigning tables in the file. The tables consists of 32 32-bit numbers. Each value from 0 to 31 (0x1f) is used exactly once.

  • The comments are based on tests with the PAL version.
  • The standard setting is: 8,1,2,4, 0,5,6,7, 9,15,11,3, 14,10,12,13, 16,20,25,26, 27,31,23,18, 21,30,29,17, 24,22,19,28
  • In the BMG message files the track names are stored beginning from message IDs (MID) 0x2454 and 0x2490. Add the slot value to find the specific messages.

Changing the order allows to move Special Slots to other places. The following command of Wiimms SZS Tools may change the track order: 

wstrt patch StaticR.rel --tracks=LIST[1]

Arena Order Tables

There are 4 copies of the track assigning tables in the file. The tables consists of 10 32-bit numbers. Each value from 32 (0x20) to 41 (0x29) is used exactly once.

  • In the BMG message files the arena names are stored beginning from message IDs (MID) 0x24b8 and 0x24cc. Add the slot value and subtract 0x20 to find the specific messages.

The following table shows the native order (not reordered by the above tables) of all arenas and the corresponding file names. Add 0x20 to the index to find the value for the assigning tables:

wstrt patch StaticR.rel --arenas=LIST[2]

Searching players for online gaming

If MKWii searches players worldwide or in regions for online gaming, it creates some text queries. These queries looks like a WHERE clause of SQL queries.

If analyzing the online communication, you can find for example the following condition string: 

... and (rk = 'vs_21' and ev >= 5215 and ev <= 8215 and p = 0)
  • vs_21 is the region name (playing in region 21).
  • At this point I had 6715 points. The Wii builds a range from 6715-1500 up to 6715+1500 and search players within this range.

In StaticR.rel you can find the following string twice (1 for racing, 1 for battle): 

%s >= %d and %s <= %d

If replacing the string by another one with the same number of characters ... 

(%s > %d or %s <= %d)

... the above query becomes: 

... and (rk = 'vs_21' and (ev > 5215 or ev <= 8215) and p = 0)

And now the inner part of the condition is always true, so that all players independent of their ranking points will be found.

The following command of Wiimms SZS Tools will exactly patch a StaticR.rel file in the described way: 

wstrt patch StaticR.rel --all-ranks[3]

Change color of HUD

The color of the Head-up display in races can be changed at the following offsets:

File offsets of the HUD-data
PAL NTSC/USA NTSC/JAP KOREA
0x399346 0x397F9E 0x398B26 0x399786

The next 4 bytes are the main color, the next 18 bytes (4+14) may describe the color of the parts in detail.

Change color of region line

In online-races, every player has a colored line under his name, pointing to his kart/bike. The color of this line is region-dependant and can be changed at the following offsets:

Region line color
PAL NTSC/USA NTSC/JAP KOREA
0x399B13 0x39856C 0x3992F3 0x399F50

The definition is 48 bytes long, each group of 4 bytes describes the color for one region in RGBA format. The original colors are the following:

Offset Usage Default Color
0x00 Unknown 3F333333 : grey, transparent
0x04 Player 1 E61414FF : red team
