i read most of it and it didn't tell me...
The guide is not going to baby you into doing it, it gives you MORE than enough information needed to learn to do it yourself.)
There are plenty of tutorials here on PC, if you don't have the initiative to at least look around for a bit, then you are not ready to ROM hack.
But since you are probably going to complain that you cant find it, I'll tell you how to do it.
There are 2 ways you can do this.
I will tell you the way I do it.
First of all, make sure this script is saved as an RBC file. (Do so by putting it into XSE and saving it...)
Now, click;
Tools
then click Batch Compiler.
Now, first, find the ROM you want to insert the script into.
Next, navigate to the folder where you saved the script.
Finally, select your script, and hit compile.
Now look for @start in the window that appeared, it should be easy to find.
Next to it should be an offset, copy that into the "Script Offset" place in A-Map.
Now simply make sure the person is configured to actually RUN the script...
(The first "Unknown" setting when you have a person highlighted in A-Map, should be set to 03)
And there you go.
