Removing the professor's speech in BW1

[AriTheSmol]

I'm trying to make a hack for black 1, and one of my goals is to remove the professor's speech and the character select screen, but I cannot find any tutorials or leads for the life of me. So far, I have gathered the following:

- The text for the section is in text file 44 of the game text
- The code is somewhere in one of the overlays (google overview said it was in 27, but it's not a reliable source)

Anyone got any pointers or anything? (I also sent this in the discord server for this site as well as some other romhacking servers; I am a desperate man)
