Should we give more prominence to the official romanized Japanese names? While they might seem simple romanizations of the Japanese names, they do not always sound like those and are more like "English versions of the Japanese names".
As an example, if I am not mistaken, Bowser should be written like "Kuppa" and instead his official romanized name is "Koopa", with only one p, but more importantly, there are puns that can only work with the Japanese names and cannot work with the official romanization, such as in the case of
this comic strip of Larry that works only because the Japanese name of Larry is written like "Rally", while its official romanization ("Larry", like the English name) wouldn't work.
Furthermore, the official romanization itself evolved, with Yossy in Super Mario World becoming Yoshi in modern material or Kamek becoming Kameck (lately, the letter "c" has been added to the official romanized names, and is even found in the games' data, with MK8 short form of Toadette being "Knc", which means "Kinopico").
For these reasons, I'm wondering if we should at least add the official romanized names along the Japanese names, as "Jap", using "JapR" for a romanization of the Japanese names that sounds more like they actually should be pronounced in Japanese.
