[Script✓] Pokémon FireRed: Disabling the One Island event (SOLVED)

Pok?mon FireRed: Disabling the One Island event (SOLVED)

I'm working on a simple romhack for a friend of mine, who wanted something different from a standard randomized Pok?mon FireRed playthrough. As a part of this, I want to disable the One Island event that takes place after beating the Cinnabar Gym.

If possible, I want to change the script so that instead of giving you the option to go to One Island, Bill instead gives you HM06 (Rock Smash). However, although I can find the strings of the event with Advance-Text, when I search for the offset of these strings XSE comes up with nothing.

Alternatively, I just want to disable the event entirely. I have noticed that the script that triggers upon defeating the Gym Leader is different for Blaine in comparison to that of the other Gym Leaders, so I assume the event must be activated here, but I don't know which parts are safe to erase and which parts would break the game when erased.

Could anybody look into this and give me a hand?

The full script can be found at 0x166FCD. I have no idea why its not showing up properly in A-Map, but oh well :/

Here's an edited version of the script which has Bill give you HM06:

Just compile it and don't do anything with the offsets it give you. Since we're unable to properly edit it in A-Map this script will go to 0x166FCD before immediately branching away to the new dynamic offset chosen for @Repoint.

Oh, thanks for the response, i want to change this script too. I have a question, Where is the location of these script in the A-Map? I tried to searching this script, but i can?t find it.

 

[Ebontope]

I've just been able to test this script and it worked like a charm! Thank you so much!

It doesn't seem to be displayed in A-Map at all for some reason. But by making 0x166FCD redirect to a new script, you can essentially change the event to whatever you want.

I see, one question, How do you know that this offset (0x166FCD) corresponds to the One Island Event? which program indicates this? thanks. I have this dude because I´m searching scripts that no appear i n the A-Map (For example, the first battle agaisnt the Rival in teh Oak's Lab and this one).

I was able to find the correct offset by opening a ROM in a HEX editor, going to 0x166F88 (the incorrect script offset displayed in A-Map) and backtracking until I reached the start of the script.

The first battle with your rival is actually fully visible in A-Map. The three script tiles in the middle of the lab have a second layer underneath, just move the ones on top out of the way and you'll be able to see it.
