Hi, it´s me again. Recently I read Zdawg´s rom hacking document and there I found one sentence related to script inserting and extracting that says: "If I'm not mistaken, YOU CAN WRITE LONGER THAN HOW LONG THE ORIGINAL SENTENCE IS!!! (- this is for script editing) ". Is this true? Also, can you tell me where can I find Jair's Script Inserter or extractor since it isn't here on Zophar or at Rom hacking?

It all has to do with pointers. A pointer's (usually) just a two- or three-byte address written in a way the machine can understand that tells the game where the start of a string is.
You can move end-of-string codes around all you want, that's not the issue. The issue is that the next string will still start in the same place, so instead of displaying what it's supposed to, it'll display the new data that you overwrote the old data with.
Am I making sense?
Incidentally, Script-I and Script-E were wonderful tools for their time, but for excellent script extractors and inserters, you'll want (respectively) the latest versions of romjuice and Atlas. Both, I think, can be found at romhacking.com.

Don't hate pointers. They're much easier than they seem. Seriously. Once you've figured out exactly what they are and how they work, you'll slap yourself and go "OH!"
