Also I found that offset in fsf, and used it in my first script, that was practically the one in the tutorial and it had the same problem until I made it like the first script in my post there.
Oki, I changed the offset of the script, and the offset of the event's script in advance map to 71A794 and it works
So how do I replace scripts offsets? :/
Also the with the script, she always says "How's Pikachu?" :/ What'd I do wrong there?
#Erase 0x812345 0xFF
Just change "0x812345" to the location where your script starts, and also change "0xFF" to how many bytes you want to erase. Hope that helped.
I will edit later and answer the other questions...
