Some Discoveries I Have Made

Washington DC, USA Hex Byte Location Mismatch

Every Region ID has a default 'geo-location'. The default geo-location for Region ID #1 (Americas) is Washington DC, USA. The hex byte (word) value for this location by the game is 0x1BA8C937. If you want to set the USA Flag on within the game if your Country is USA, you can access the Region Settings. You will be navigated to the hidden Region-Select Channel. After connecting online to the server that holds files that contains all these Region Settings, you can select a variety of locations within USA.

The top/first option is Washington DC. If you select his location and take a view of the hex byte value for this location on the SYSCONF file, the value is 0x1BA8C938. One number higher than the other value, a mismatch.

This doesn't happen for any of the other default geo location values for the other Region IDs.

Country Code 0xFF; Region Residence Code 0xFF

If your country code value in SYSCONF is 0xFF and the region residence code (location setting within country) is also 0xFF, the game will preform a series of instructions (around the function subroutine that is for applying your Region ID) and force you to use the default geo-location of your Region ID (no flag image).

Remnants of a Chinese Disc Region

There are 4 Disc Regions. These Disc Regions are not MKWii Region ID's. The Disc Region is a byte which you can find in the Region.Bin file of an extracted ISO/WBFS file via Wiimm's WIT Tools.

List of Disc Region Values:

  • 0x00 = Japan (Traditional/Taiwan Games use this Disc Region, Nintendo only made 8 Taiwan Games)
  • 0x01 = America
  • 0x02 = PAL
  • 0x03 = Unused
  • 0x04 = Korea

These Disc Region bytes are read by your System Menu. If the Disc Region doesn't match the region of the System Menu, the disc will not be read in the Disc Channel.

Over time, there has been speculation of a never-released Simplified Chinese (China) MKW Disc due to the fact that there is a Region ID #6 (China). Also, along with the speculation of a never-released Chinese Wii made for the Chinese MKW Disc. At Memory Address 0x8028AF09 on the Korean Mario Kart Wii, there is a hex ASCII byte representing 'CN'. The 'CN' comes right after the four other listed Disc Region Abbreviations. A very likely indicator of remnants of a Disc Region for the Chinese System Menu of the Chinese Wii. Considering the fact the the 'CN' is listed after the other four Disc Regions, and the four Disc Regions are listed in order, the Chinese Disc Region may use the value of 0x05.
