Here all the messages that could not be displayed in the hack will be displayed, in hexadecimal order, just like lunar. To make it easier to identify which level the message is, I will put the name of the level and the screen where the message would be displayed, so that we have a context of the story, which I will also put in.

Following this format:

Level:
Message:
Screen:

Note: Ignore db""; this is part of the message code; I just got too lazy to remove it. Remember that there can be two messages on the same level; here they will be displayed like this:
ex: message 01
message 02

db "forest, but now we"
db "will finally be able to leave "
db "Here, as a reward, I will."

Note: This message is incomplete, as it would need another one, but since I still need to configure the Toads, it was left like this.
