Scripting (cutscene and dialogue editing) is more challenging, but it has its own tutorial video. See the [[FAQ#Scripting|scripting]] section for more information.

=== After playing for a while, I decided I want to change some of the settings. Can I use the randomizer to make that change without affecting anything else? ===

No. If you saved the settings and seed used for randomization, you could load them into the randomizer, change whatever settings you want, and then randomize a new ROM with them. Although even if you do that, you'll likely get a completely different result.

Maybe. If the hack has made important internal changes to the game, the ranomizer might not be able to randomize it. If you get errors, try disabling some of the options.

=== How do I add new Pokemon? ===

The easiest thing you can do is replace some of the unused slots with the new pokémon you want to add. These are the slots that can be replaced:

These slots are labeled “??????????”, and can be found in entries #537-551. They aren’t used anywhere so feel free to replace them with other pokémon you want to add to the game.

Only certain Unown letters are needed to complete Aegis Cave (specifically, letters I, C, E, R, O, K, S, T and L). If you need extra slots you can replace the rest of Unowns with something else. If you do it, make sure to remove them from Aegis Cave’s pokémon spawn lists.

These entries can be found at the bottom of the list, and are labeled “reserve_xx”. These entries can’t be used inside dungeons since they don’t have stats, so you can’t edit them to add new pokémon, however they can be used as actors (NPCs) in cutscenes.

SkyTemple also includes the experimental ExpandPokeList ASM patch, which can be used to expand the available slots. Keep in mind that we still don't know if the patch can cause issues when applied, so it's advised to only apply it after you run out of unused slots. If you do so, make a backup beforehand.

=== How do I add new dungeons? ===

=== How can I edit items? ===

=== How can I edit moves? ===

In order to do this you will have to write ASM code (you can also use the [https://asmeditor.skytemple.org/ EoS code editor] by Techticks if you prefer a GUI, although you should keep in mind that it’s a bit outdated and it’s missing many of the functions that have already been documented) and then import the .asm file as a move / item effect in SkyTemple with the “Import code” option found in the “Move effects” / “Item effects” menu.

SkyTemple includes the AddTypes patch that can be applied to add the fairy type to the game. Adding more types would be more complicated, since there’s only one unused type string (neutral), which is replaced by fairy when applying the AddTypes patch.

Even after applying the patch, you’ll still have to manually assign that type to pokémon and moves, as well as implementing new moves yourself.

Boss battles take place in fixed rooms (aka fixed floors), which you can edit in the “fixed rooms” section. There are some things you should know about them:

The list of entities, pokémon, items... that can be placed in fixed rooms (which you can edit by double clicking the “fixed rooms” option) can’t be expanded, so you will need to replace some entries there if you want to add new bosses. The pokémon list has some unused Groudon entries starting at #101 that you can replace.

You can use the "Go to" button under the music list (or manually navigate to "Lists > Dungeon music") to see and edit which 4 songs are included in each random entry (under the "Random music" tab).

=== How can I change the pokémon that are added to your team during certain dungeons (like Bidoof during Craggy Coast)? ===

To change the data of these pokémon, as well as which dungeons add them to your team, you can use the "Lists > Guest Pokémon" menu, available after applying the EditExtraPokemon patch.

Unfortunately, this is not inside the script engine and is hardcoded. You can individually change each question and answer in text strings, but not the test logic or weights assigned to each answer, or any other parts of it such as the background or BGM. Starter choices, however, can be modified in “Lists” → “Starters”.

Yes, you can apply the ChooseStarter patch to do this. If you also want to remove the personality test you can also apply the SkipQuiz patch.

This kind of editing is known as [[scripting]], since you will need to modify the game’s scripts. You can find a tutorial [https://www.youtube.com/watch?v=6SfThAf_sos here], and a playlist with multiple tutorials [https://www.youtube.com/playlist?list=PLeoQCzDApD5Kmp0eRA947oPelXunAtqWv here].

Go to script “S02P01A”, then under “Acting (ssa)” open “m00a01a”. Scroll down until you see “case 28” (Should be line 270 if you haven’t made any changes to that file yet). Copy the contents of case 28 except its last line, which should be<syntaxhighlight>

Internally, scripts are stored in a binary format that uses .ssa/.ssb files. SkyTemple decompiles them to a custom language created by Capypara called [[ExplorerScript]] to make it easier to edit them and then compiles them back to the format used by the game. You can find the ExplorerScript language specification [https://explorerscript.readthedocs.io/en/latest/language_spec.html here].

You are missing some Windows files required to appply patches and run the randomizer. Visit [https://www.microsoft.com/en-US/download/details.aspx?id=48145 this link] and download both the x86 and the x64 versions of the C++ Redistributable, then install them, restart the randomizer and try again.

==== I tried to randomize my ROM and I'm getting errors or strange side effects, such as all the NPCs being randomized to the same pokémon. What happened? ====

This can happen if you try to re-randomize a ROM that was already randomized before. The randomizer cannot work with ROMs that have already been randomized, you need to use an unmodified ROM.
