Question. Aside from banner.bin which holds the game icon, do you recall the alternative game icon found in NSMB's files, specifically in the /ipl/ folder?

According to the wiki, it's used solely for DS download play:

File path	description
/ipl/	Contains bitmap and palette for the DS Download Play banner icon

However, I seem to recall having to change it in the past (and not just banner.bin); I think some flashcarts or emulators might use it, and I wanted to verify this claim as there is nothing to back it up aside from my memory; I may very well have it the other way around.

This is not some important question, but I'm writing up whatever documentation and tutorials I can; I'd like to be accurate where possible.
