*Serial Number Prefixes do not include the Non-GCN Wiis & Wii Mini. Non-GCN Wiis came out sometime in Oct/Nov 2011 and start with the letter K instead of L. Wii Minis came out sometime in Dec 2012. Also, Nintendo never made Korean or Taiwanese Wii Minis.
**Since the Taiwan Wii uses the Japanese MKW Disc, there is no actual Nintendo official release date for a Taiwan MKW since a Taiwan MKW doesn't exist. So in technical terms, the "Taiwan MKW Release Date" is the same date Nintendo released the Taiwanese Wii
***In the Chinese MKW Regional Top 10, there is a player that has a name in Simplified Chinese. This name cannot be read by any MKW Disc. Thus, by deductive logic it is safe to say that there is a Chinese MKW Disc. Also, this means that his Mii name
must have been created from a Mii Channel that is supported by a System Menu that can display Simplified Chinese. Using AnyRegionChanger, putting S.Chinese on my System Menu results in a brick (except Korean, but it only changes the language for the screen that appears when the
Wii Remote Home button is pressed). So it is safe to say, that there is a Chinese Wii. Please do not the confuse
the game ID of RMCC01 for what is known as the "Taiwanese ISO", that ISO is a custom Japan ISO made by a Taiwan
Player by the name of [A9 Star]. The ISO is in Trad. Chinese, not Simplified Chinese. The official letter
code by Nintendo for Trad. Chinese (Taiwanese) games is "W", not "C". Example: SSQW01 (Game ID for Taiwanese
Mario Party 9). To understand this info better, please visit this forum thread about MKW Region IDs - HERE
Also, there is another player that has what is known as "Korean asterisk symbols" in his/her name. We know that the Chinese Mii Channel has that large asterisk symbol which can only be found in the Korean Mii Channel. All Wiis can read the large asterisk symbol.
