Finding and exploiting hidden features of Animal Crossing's NES emulator (2018)

This video was how I found the James Chambers blog and submitted the story. It's good and uses the medium well. The YouTuber demonstrates the letter score system in real time with a custom romhack.

Here is how I summarized the video elsewhere:

> In the English release of the original 2001 Animal Crossing game, they checked capitalization, English trigrams, runs of repeated characters, ratios of spaces to non-spaces, and sentence length in order to score your letters to villagers and simulate the villagers understanding the letters. Capitalization is worth more than trigrams, so the game is vulnerable to spamming a capital letter followed by a period with some spaces thrown in.

From what I can tell, some debug symbols failed to be removed from release versions of the game:

Also, there were source code leaks for the iQue version of this game and other Nintendo games and consoles in 2020, but I don't know if that contributed anything additional in that regard:
