Halfman, to get a real "custom" script you have to make it yourself.
For this, you need notepad, brain, keyboard and ability to use them simultaneously.
If you can't, ask someone you know that can. He doesn't have to be necessary eA scripter or w/e.
About warper, open some Warper script that you have, and that has all needed + unnecessary warps.
Look for map names you don't want to have in, like abbey02, abbey03, tur_dun04.
See when are they triggered. Backup your file, delete a part you think is not needed. Try using script, see if it throws any errors. Try again.
Like that, you will get some basic experience of scripting, which leads you to even more experience of scripting, and makes you able to do things you want without relying on others. And that's useful for both you and "others".
Plus it's more secure. If you make a script yourself, you can make sure it doesn't have any exploits or stuff. If someone gives you a script, how can you be sure it's safe without checking yourself~?
Well if you really are lazy or have absolutely no knowledge in programming/scripting, then I may be able to do that for you if you give me the source script.
Have a nice day~
