Thank you for your elaboration on the page for [[Professor Oak's lab tilemap corruption glitch]]! [[User:Sherkel|Sherkel]] ([[User talk:Sherkel|talk]]) 12:09, 14 February 2019 (-06)
: Thanks! I'm still trying to figure out the seemingly random circumstances that cause the sprite overflow. Currently the most useful clue I have is the characters ":" and "e" on the first line of the corrupted tilemap, which are hex 9C and A4 respectively. Those should correspond to the OAM entries of a male aide who is 4 pixels away from being fully off-screen. <s>This is interesting because the player walks at 2 pixels per frame, meaning that it's not a simple off-by-one-frame error.</s> I need to understand more about the overworld loop and sprite updating to make sense of this.

:: Never mind, I just realized that all sprites are drawn 4 pixels higher, meaning that when the player walks up, they are designed abruptly disappear when they are still on screen by 4 pixels. Therefore the glitch indeed happens on that one exact frame. [[User:Bbbbbbbbba|Bbbbbbbbba]] ([[User talk:Bbbbbbbbba|talk]]) 18:02, 14 February 2019 (-06)
