Chriskid198:
well, you almost have it right. Just fix the tiles so that they line up/look right. I think it looks correct so far. The corrupted border tile... not completely sure, but try filling it in with a tree sprite and see how that works.
IceArceus:
Open Advance Map and your rom in there, and find where you want your character to be. Then click the Events tab and scroll all the way down. Add 1 to the Person events, and click Change Events. Look at the farthest upper left tile on the same map, and drag the player sprite to where you want him to be. Mess around with the Picture No. for which sprite the character uses. As for his script, use HxD to find a suitable empty spot(Free Space Finder isn't what I like to use; I like HxD better because you get to choose), and type in that offset in Script offset. Then, go into XSE, open your rom, go to THAT offset, and type out your script. If you need help, I might be able to assist with the format. Once you're done, click the gear button; the one whose alt message is Compile. That saves the script to the offset you're at, which is what you want. I don't really like Script Generator all that much because it seems to choose a random empty spot, and it wastes space because there's other empty spots that aren't used right before it; EX: 08800000 is empty, and it chooses 08810500 or similar.
