The Pokemon Crystal intro is fairly complex to modify and requires quite a deal of assembly knowledge to modify. Thankfully, if you're planning on giving your hack a new story, it's not hard at all to just remove the intro. This change will skip straight to the title screen directly after the game freak intro with ditto plays.

Go to [/engine/movie/intro.asm](https://github.com/pret/pokecrystal/blob/master/engine/movie/intro.asm) and search for "IntroScenes" in your text editor. You should see something like so:

```
IntroScenes:
	dw IntroScene1
	dw IntroScene2
	...
	dw IntroScene27
	dw IntroScene28
```

This is the section in which Crystal loads sections of the intro (i.e. Unown appearing, Suicune running). It should be fairly obvious what to do here: just remove lines IntroScene1 through IntroScene27.

It should now look like this:

```
IntroScenes:
	dw IntroScene28
```

Compile and load the ROM. It should now do exactly as described above, with no errors. 

Optionally, if you want to reduce space, you can also remove these intro scenes entirely, and it will still work. Not far from this you'll see "IntroScene1:". All the code for the intro scenes are right next to each other, so you can simply highlight from here all the way down to before `IntroScene28:` is mentioned delete everything selected. Make sure, however, you don't remove the `NextIntroScene` code. This is still required to switch from the Game Freak logo to the title screen.
