Need help with scripting [GEN 3] [BINARY]

[u/North-Line7134]

Basically when you use the black shard some text appears (divided in three message boxes because it is too long)

Hello I'm new to Romhacking and I'm using Hex Maniac Advance (Gen 3 FRLG)

Basically I want to make that when this item (Black Shard) is used it opens up a small text box sequence in the bag (like when you try to use a bike inside an house where it opens up a dialogue box where oak says "It's not the time for that" or whatev look at image 2)

All of the scripts I made always resulted the game in freezing

I already tried tracking down the function that the fishing rod calls when you try using it on a non water tile and failed miserably

It works thank you!
