If you need a Script and you don't want to take up new space, you can copy this one, I use it for my hackroms.
What you should do is copy it into the original Move Remember script and that's it!
(What you do is check an item, and if you have it, it will let you remember the moves for free. In this case, check the item "Teachy TV"
that we got at the beginning of the game, but it would work with any other item).
And a little video, if you want to see it in action:
