[Script] Help needed about a setmaptile error

[Entaro Ceraphenine]

Hello. This is my first post here.

I am working on a FireRed ROM Hack and in one particular map, the use of setmaptile creates errors. This is my script:

Spoiler:

#dynamic 0xA061A9

#org @main
checkflag 0x612
if 0x1 call @set
end

#org @set
setmaptile 0x39 0xC 0x91 0x0
return

And it is placed in the Script type '01 "setmaptile" script' in Advanced Map. But once I click save, it shows the error: AdvancedMapError(3): Cannot change byte at pos 0! Please contakt [email protected]

The last time I put this script in the game, the game crashed everytime a wild battle started. It either froze or restarted after selecting a move. I don't see any other errors occurring and the setmaptile itself works alright. And backup files of the ROM without the setmaptile script also works perfectly. So I am suspecting that the setmaptile script is the culprit.

Can someone tell me what to do? Thanks in advanced. Also, I am a bit of noob in scripting.

Maybe try a script like this:

EXAMPLE:

#dynamic 0x800000

#org @start
setmaptile 0xB 0xA 0x9 0x7
special 0x0
release
end

If you are new at scripting, try here.
