I am currently making a Rom hack for fire red. I am having trouble with creating a person event to give the player the national pokedex after they get the regular pokedex. I created the person event with advance map and then used FreeSpaceFinder and XSE with a national dex script I  found on the internet. I think the issue is either the script is written wrong or my FreeSpaceFinder isn't working properly. If anyone out there has a script that works or knows where to get one it would be much appreciated.

UPDATE:

I went in and changed a few things with the script i found on the internet and was able to get the character event to talk through the first text box, then the second was blank and the game froze. I feel like I am getting closer to the solution but any advise or tips would be helpful. Here is a copy of the script i used.

#dynamic 0x80000

#org @start
lock
faceplayer
msgbox @talk1 0x6
special 0x16F
msgbox @talk2 0x6
waitfanfare
closeonkeypress
fadescreen 1
setflag 0x1208
fadescreen 0
release
end
