Faster berry interactions (Emerald)
This is a tiny mod that makes dealing with berries (planting, watering, picking) quicker by removing some unnecessary dialogs.

Demonstration: streamable.com/fsn46f (sorry for the cheesy playername)

• Removes these messages:
  
  "[Player] put away the [berry] in the Berries pocket."
  "The soil returned to its soft and loamy state."
  "[Player] watered the [berry]."
  "The plant seems to be delighted."​
• If you have berries, skips the "It's soft soil" message and opens your bag immediately
• Merges the "Want to water[...]?" question with the growth stage message (e.g. ORAN has sprouted. Want to water[...]?)

Diff: github.com/dunsparce9/pokeemerald-tweaks/commit/40685e
In short: Only berry_tree.inc is edited. WantToPlant is replaced with ChooseBerryToPlant, BerryGrowthStage messages are edited to include the "want to water?" question (I couldn't find a way to add more text without displaying another message so I had to copypaste the same wailmer check for all 4 labels, sorry :D), CheckBerryFullyGrown is edited to skip to PickBerry, and messages that are now unused are removed.

Had to remove the https because this is a new account 🙃
I built and tested these changes with my old save, but feel free to test them yourself, this is my first mod so please tell me if it doesn't work.

Show Type Effectiveness In-Battle [EM]​

Now with Doubles, Flying Press/two-typed moves, and Inverse Battles support!
​

First thing you're going to want to do is to go into graphics\battle_interface, move text.pal to somewhere safe (I don't think the edits I made to this file harm anything, but better to be safe than sorry) and delete text.gbapal and text.gbapal.lz. Now, download the attached text.zip file, and move its contents (which is just a new text.pal) into the graphics\battle_interface folder.

Now, we get to the fun coding part!
Open up src\battle_message.c, search for sTextOnWindowsInfo_Normal, and add this to the bottom of this array:

Spoiler:

{ // 24 "type" super-effective
	.fillValue = PIXEL_FILL(0xE),
	.fontId = 7,
	.x = 0,
	.y = 1,
	.letterSpacing = 0,
	.lineSpacing = 0,
	.speed = 0,
	.fgColor = 6,
	.bgColor = 14,
	.shadowColor = 5,
},
{ // 25 "type" not very effective
	.fillValue = PIXEL_FILL(0xE),
	.fontId = 7,
	.x = 0,
	.y = 1,
	.letterSpacing = 0,
	.lineSpacing = 0,
	.speed = 0,
	.fgColor = 1,
	.bgColor = 14,
	.shadowColor = 3,
},
{ // 26 "type" no effect
	.fillValue = PIXEL_FILL(0xE),
	.fontId = 7,
	.x = 0,
	.y = 1,
	.letterSpacing = 0,
	.lineSpacing = 0,
	.speed = 0,
	.fgColor = 11,
	.bgColor = 14,
	.shadowColor = 11,
},

Now, open src\battle_bg.c, and add this to the bottom of gStandardBattleWindowTemplates (make sure you paste this before DUMMY_WIN_TEMPLATE, though):

Spoiler:

{ // super effective
	.bg = 0,
	.tilemapLeft = 21,
	.tilemapTop = 57,
	.width = 8,
	.height = 2,
	.paletteNum = 5,
	.baseBlock = 0x02a0,
},
{ // not very effective
	.bg = 0,
	.tilemapLeft = 21,
	.tilemapTop = 57,
	.width = 8,
	.height = 2,
	.paletteNum = 5,
	.baseBlock = 0x02a0,
},
{ // no effect
	.bg = 0,
	.tilemapLeft = 21,
	.tilemapTop = 57,
	.width = 8,
	.height = 2,
	.paletteNum = 5,
	.baseBlock = 0x02a0,
},

The final bit for this code belongs in src\battle_controller_player.c.
We're going to start by adding these defines at the end of the list of defines toward the top of the file:

#include "constants/battle_move_effects.h"
#include "event_data.h"

This is necessary for getting the Inverse Battle flag later on, and for getting the move effects for two-typed moves.

Next, define a new method at the top of the file. You can place it anywhere, but I searched for:

static void MoveSelectionDisplayMoveType(void);

And placed it above it. The method we are defining is:

static void MoveSelectionDisplayMoveTypeDoubles(u8 targetId);

The reason we're defining a whole new method for this here is because it's a bit easier than adding a 1 to every MoveSelectionDisplayMoveType call that happens in this file. If you wanted to, you could replace every MoveSelectionDisplayMoveType(); in the file to MoveSelectionDisplayMoveType(1); and replace the MoveSelectionDisplayMoveType method with the MoveSelectionDisplayMoveTypeDoubles method from later in this post and everything should work the same.

Now, we're going to be copying over the effectiveness table from src\battle_util.c of DizzyEgg's Battle Engine.
I placed this toward the top of the file, under "unknown unused data".

Spoiler:

#define X UQ_4_12

};

#undef X

(If you're not using DizzyEgg's Battle Engine for whatever reason, just eliminate the last line and the last column of this table to get rid of Fairy and it should work fine.)

Now, search for MoveSelectionDisplayMoveType(void), and add these three methods above it:

Spoiler:

static void MulModifier(u16 *modifier, u16 val)
{
	*modifier = UQ_4_12_TO_INT((*modifier * val) + UQ_4_12_ROUND);
}

u8 TypeEffectiveness(struct ChooseMoveStruct *moveInfo, u8 targetId)
{
	bool8 isInverse = (B_FLAG_INVERSE_BATTLE != 0 && FlagGet(B_FLAG_INVERSE_BATTLE)) ? TRUE : FALSE;
	
	if (gBattleMoves[moveInfo->moves[gMoveSelectionCursor[gActiveBattler]]].power == 0)
		return 10;
	else
	{
		u16 mod = sTypeEffectivenessTable[gBattleMoves[moveInfo->moves[gMoveSelectionCursor[gActiveBattler]]].type][gBattleMons[targetId].type1];

		if (gBattleMons[targetId].type2 != gBattleMons[targetId].type1)
		{
			u16 mod2 = sTypeEffectivenessTable[gBattleMoves[moveInfo->moves[gMoveSelectionCursor[gActiveBattler]]].type][gBattleMons[targetId].type2];
			MulModifier(&mod, mod2);
		}

		if (gBattleMoves[moveInfo->moves[gMoveSelectionCursor[gActiveBattler]]].effect == EFFECT_TWO_TYPED_MOVE)
		{
			u16 mod3 = sTypeEffectivenessTable[gBattleMoves[moveInfo->moves[gMoveSelectionCursor[gActiveBattler]]].argument][gBattleMons[targetId].type1];
			MulModifier(&mod, mod3);

			if (gBattleMons[targetId].type2 != gBattleMons[targetId].type1)
			{
				u16 mod4 = sTypeEffectivenessTable[gBattleMoves[moveInfo->moves[gMoveSelectionCursor[gActiveBattler]]].argument][gBattleMons[targetId].type2];
				MulModifier(&mod, mod4);
			}
		}

		// 10 - normal effectiveness
		// 24 - super effective
		// 25 - not very effective
		// 26 - no effect

		if (mod == UQ_4_12(0.0)) {
			if(isInverse)
				return 24;
			else
				return 26;
		}
		else if (mod <= UQ_4_12(0.5)) {
			if(isInverse)
				return 24;
			else
				return 25;
		}
		else if (mod >= UQ_4_12(2.0)) {
			if(isInverse)
				return 25;
			else
				return 24;
		}
		else
			return 10;
	}
}

static void MoveSelectionDisplayMoveTypeDoubles(u8 targetId)
{
	u8 *txtPtr;
	struct ChooseMoveStruct *moveInfo = (struct ChooseMoveStruct*)(&gBattleResources->bufferA[gActiveBattler][4]);

	txtPtr = StringCopy(gDisplayedStringBattle, gText_MoveInterfaceType);
	txtPtr[0] = EXT_CTRL_CODE_BEGIN;
	txtPtr++;
	txtPtr[0] = 6;
	txtPtr++;
	txtPtr[0] = 1;
	txtPtr++;

	StringCopy(txtPtr, gTypeNames[gBattleMoves[moveInfo->moves[gMoveSelectionCursor[gActiveBattler]]].type]);
	BattlePutTextOnWindow(gDisplayedStringBattle, TypeEffectiveness(moveInfo, targetId));
}

Obviously, you can remove the whole two-type move check if you're not using DizzyEgg's Battle Engine.

And in MoveSelectionDisplayMoveType, change this line:

BattlePutTextOnWindow(gDisplayedStringBattle, 10);

To this:

BattlePutTextOnWindow(gDisplayedStringBattle, TypeEffectiveness(moveInfo, 1));

Now, we just need to add calls for MoveSelectionDisplayMoveTypeDoubles. Search for HandleInputChooseTarget(void) and find the two places that use this switch statement:

switch (GetBattlerPosition(gMultiUsePlayerCursor))

Immediately after these switch statements, add this line:

MoveSelectionDisplayMoveTypeDoubles(GetBattlerPosition(gMultiUsePlayerCursor));

And you should be good to go!
Thanks to DizzyEgg for his hard work on the Battle Engine upgrade. The type effectiveness table and the MulModifier method made things very easy once I figured out how the palettes worked. I for sure would not have been able to do this without those.

Show Type Effectiveness In-Battle [EM]​

Someone on Discord gave it a shot and got an error. They then asked me if I got the same error, so I gave this a try as well and we got the exact same error.

I made a disposable branch pretty quickly to show off the exact changes to the code.
If it's not too much to ask, could you please check if everything's correct?

Man, I am not on my game recently, haha. In MoveSelectionDisplayMoveType, the line should be BattlePutTextOnWindow(gDisplayedStringBattle, TypeEffectiveness(moveInfo, 1));, I forgot to add in the "1" in my original tutorial. I'll edit it now. My apologies.

[Pokeemerald] Saveblock Cleansing

The game is saved in sets of saveblock chunks, 3968 bytes each. Saveblock2 is 1 chunk, while Saveblock1 is 4 chunks (15872 bytes). Unfortunately, the former only has 84 bytes remaining, while the latter has only 120 bytes remaining before these sizes are reached.

This removes some likely superfluous saveblock data to allow more custom data to be saved. Each section removed is given a define, so you can toggle on/off whatever you want. (see the top of include/global.h). In total, roughly 3082 bytes have been opened up:

Spoiler:

// free saveblock 1 defines
#define FREE_EXTRA_SEEN_FLAGS           //free up extra pokedex seen flags. Frees up 104 bytes
#define FREE_FIELD_3598                 //frees up unused saveblock data. 384 bytes

                                        //grand total: 3082

Here is the repo.
How To Add:

• git remote add ghoul https://github.com/ghoulslash/pokeemerald
• git pull ghoul saveblock

Other areas to clean more data that are not included in the repo (reduce to values of 1 to prevent compiler errors)

Tv Shows - 900 bytes - change TV_SHOWS_COUNT in include/constants/global.h
Record Mixing Apprentices - 272 bytes - change APPRENTICE_COUNT in include/constants/global.h
Mail - 576 bytes - change MAIL_COUNT in include/constants/global.h
Secret Bases - 3200 bytes - change SECRET_BASES_COUNT in include/constants/global.h

I don't expect that the base game will be affected by these changes, but if anything breaks please report it to me.

Showing IVs/EVs in Summary Screen [EM]​

I found another way to showing when page is Skills screen.
find static void Task_HandleInput(u8 taskId) and add code between else if

	PrintTextOnWindow(AddWindowFromTemplateList(sPageSkillsTemplate, PSS_DATA_WINDOW_SKILLS_STATS_LEFT), gStringVar4, 28, 1, 0, 0);
}

now if you are at stats screen,just press L button the regular stats will change to IVs,and if press R button, EVs will shown.
I didn't using DizzyEgg's colored-nature mod.

I found another way to showing when page is Skills screen.

Awesome job! My original code doesn't display the nature coloring when showing IVs/EVs anyway, so this is perfect.

EDIT: So, I modified this a bit to look a bit cleaner when using DizzyEgg's code anyway since I was bored, and I added another if statement to show the normal stats again when pressing Start. I have also added this to my original post.

I added one more else if in static void Task_HandleInput(u8 taskId) (and changed around the numbering a bit):

Spoiler:

        // show IVs/EVs/stats on button presses
        else if (gMain.newKeys & L_BUTTON)
        {
            if (sMonSummaryScreen->currPageIndex == PSS_PAGE_SKILLS)
            {
                BufferIvOrEvStats(0);
            }
        }
        else if (gMain.newKeys & R_BUTTON)
        {
            if (sMonSummaryScreen->currPageIndex == PSS_PAGE_SKILLS)
            {
                BufferIvOrEvStats(1);

Here's my version of BufferIvOrEvStats using DizzyEgg's nature-color mod:

Both are tested, and both work like a dream. Thank you for your hard work!

[Pokeemerald] Bag Sorting

When trying to implement this, pressing start functions fine, but pressing A on items in pockets that don't have 3 options by default (every pocket but Berries and Items) causes one of the sorting options to come up.

I pulled straight from your repo--is this happening on your end as well, or is this caused by something else I've implemented?

Pokemerald: Skip Rayquaza intro.
In src/intro.c, inside static u8 SetUpCopyrightScreen(void)
We replace

SetMainCallback2(MainCB2_Intro);

with

SetMainCallback2(CB2_InitTitleScreen);

Scrolling Multichoices In Scripts

I was asked to implement this, so here it goes. Just so you know, scrolling lists are already coded in, they're called list menus in pokeemerald. Check out list_menu.h and list_menu.c.

Updated lines in this spoiler:

Spoiler:

I put the code in script_menu.c, but you can put it whenever you want.
At the top of file make sure to include the header for the list menu. Add this.

#include "list_menu.h"

At the end of the file paste all this code. Updated lines in this spoiler:

Spoiler:

Then, add this macro at the end of asm/macros/event.inc.

	setvar VAR_0x8007, \show,
	setvar VAR_0x8008, \b,
	callnative ScriptMenu_ScrollingMultichoice
	waitstate
	.endm

How to use it? I provided two example sets of multichoices. Let me explain.

Spoiler:

Under the // Text displayed as options. comment I put all the strings that are displayed as options. Now, you may put the strings at any location, but keep in mind if the file location is different, you'll need to extern them.

Spoiler:

static const u8 sText_Example1[] = _("Example 1");
static const u8 sText_Example2[] = _("Example 2");
static const u8 sText_Example3[] = _("Example 3");
static const u8 sText_Example4[] = _("Example 4");
static const u8 sText_Example5[] = _("Example 5");

Then, under the // Sets of multichoices. comment I put all the sets of multichoices. What I mean by that is simply the options the player will be able to choose from. The syntax is simple, string name and id. The id is basically what you'll get in gSpecialVar_Result after the player chooses.

Spoiler:

static const struct ListMenuItem sSet1[] =
{
    {sText_Example1, 0},
    {sText_Example2, 1},
    {sText_Example3, 2},
    {sText_Example4, 3},
    {sText_Example5, 4},
    {sText_Example6, 5},
    {sText_Example7, 6},
    {sText_Example8, 7},
    {sText_Example9, 8},
};

And finally we have // Table of your multichoice sets. comment. As you may guess, this is the table with pointers to the multichoice sets along with the information how many options there are. Syntax is simple, set name and the number of options to choose from(I used a handy macro and advise you to do the same.)

Spoiler:

struct
{
    const struct ListMenuItem *set;
    int count;
} static const sScrollingSets[] =
{
    {sSet1, ARRAY_COUNT(sSet1)},
    {sSet2, ARRAY_COUNT(sSet2)},
};

Calling it from a script is simple, just use the macro you just put. The arguments are:
- set id(sScrollingSets table)
- window x
- window y
- amount of options showed at once on window
- whether the player can press B(if TRUE, the return value is 0x7F just as from normal multichoice)
Whichever option the player chooses is stored in gSpecialVar_Result.

Example:
scrollingmultichoice 1, 2, 3, 5, TRUE

I also have the code in my github branch called script_multichoice, so you can pull directly from it.

A couple of functions in this code are outdated. I have highlighted them in red in the spoiler below. Derived from GriffinR on the Discord. Would be great to add this update to the index at the start of this thread or to the original post.

[Pokeemerald] Pokemart Items by Badge Count

Shop Items have been based on badge count rather than city/town for a while, now. This repo sets up shop items based on Gen 8 badge counts.

The repo.

Usage:
Replace pokemart *itemList with:

pokemart 0

How To Add:

• git remote add ghoul https://github.com/ghoulslash/pokeemerald
• git pull ghoul mart-badges
• If you wish to change the item lists, just change sShopInventory_ZeroBadges (or whatever badge-count you care about) in src/shop.c

Alternatively, follow the wiki post

Hello everyone, just a quick post to let you know the main post has been given a long overdue update! Apologies for the wait. I've been away from the forums for some time due to virus-related family issues. Thanks for your patience and sorry again! x

 

[blakcat]

Yeah, it doesn't seem to work. I asked TheXaman about this on his profile back in March and he never really answered.
I guess this is a good time to post this. I really should have done it sooner, but I kind of forgot :P

Overworld 1HP Poison Survival [EM]
Some time ago, Blurose made his own version of this mechanic for his project in Pokeruby.
Some months ago, I ported it to Pokeemerald, and this seems to be a good time to post it here as an alternative.

The relevant modifications can be seen in this commit, it's veery simple.

A small issue I found with this: if the player has only 1 pokémon, the game will show the "{POKEMON} has fainted" instead of "{POKEMON} survived the poison", but the pkmn will still survive with 1 HP.

Uh... then you probably didn't apply all the changes shown in the commit.
The very last change done to the src/strings.c file shows very clearly how I change the text string labeled gText_PkmnFainted3 from "{STR_VAR_1} fainted…\p\n" to "{STR_VAR_1} survived the poisoning.\nThe poison faded away!\p".
I don't think you noticed it, but one of the 2 GIFs I uploaded in the very post you quoted shows how everything is working correctly, be it with 1 Pokémon on the party or more, in fact.

Change the title screen music [EM]​

In pokeemerald/src/title_screen.c, find this line:

[B]m4aSongNumStart([COLOR="Red"]MUS_TITLE3[/COLOR]);[/B]

Replace MUS_TITLE3 with the name of a different song. The names of all the songs can be found in pokeemerald/sound/songs/midi.

So for example, replace it as such:

[B]m4aSongNumStart([COLOR="SeaGreen"]MUS_SATTOWER[/COLOR]);[/B]

I know for 100% sure that I changed that string -- because I tested it and it was saying the correct thing -- but I think I know what may have happened. I think, when I merged a decap branch, it may have overwritten that change. Ive double checked, and it did get reverted (and I've now fixed it).

Thanks for the reply, and sorry about the false alarm.
