Editing the Pokémon Blue title

I'm currently trying to edit the title so it reads "Green Version".

However, the map data (0x45a1-0x45a9) is only 8 tiles long when the code in Green Version (0x49db-0x49e3) is 9.

I'm basically trying to go from this:

61 62 63 64 65 66 67 68 50

to this:

61 62 63 7f 64 65 66 67 68 50

Is there anyway to add that extra tile without disturbing the rest of the code?

Replacing the pointer (459C-459D) with 507C will allow you to put the new data at 7C50. You can read more about pointers here:

You'll have to repoint the data to a spot with more space available and then that's it.

Alright, so far so good. I repointed the data to 0x7c60.

However now the text has to be recentered.

Is there a pointer for where in the VRAM the text is supposed to start, or for how far to scroll it?

It's right there with the pointer to the tilemap. Change the byte at 0x4599 to be 0x46 instead of 0x47 and it will be moved over to the left one tile from where it is in your screenshot.
