It checks your bag if you have the Exp. Share. If you do, then your team will each get 50% of the experience (I suggest you turn your Exp. Share into a Key Item if you want to apply this into your Ruby hack but I really suggest you either hack Emerald or FireRed instead...). The experience gain is reduced to 50%, regardless if you have the item and who's active during the battle. (It's why I decided to remove the feature in the next beta of my hack.)

Constant Base Power For Hidden Power [FR]

Starting with XY, Hidden Power's base power was fixed at 60. Prior to this, it varied between 30 and 70, based on the Pokemon's IVs. To force the game to read the base power from the move data table, null out the strh at 0x0802B722.

Basically, replace:

Code:

0x0802B722: 28 80

with:

Code:

0x0802B722: C0 46

After you've done that, HP will use the base power in the table as its base power. Unfortunately, in a vanilla FR it is listed as 0x01, so it will be very weak until you change it. Change the byte at 0x8251721 to 0x3C to give it a base power of 60 (as in XY).

This effects both the actual damage calculation and when you view the Known Moves screen.

(Not So) Hidden Power [FR]

By default, Hidden Power will always display as a Normal-type move. By modifying the routines for displaying the types of moves, we can force it to display as the actual type.

Unlike the earlier parts of this post, this requires some free space. Here's the code:

As usual, insert it at an offset ending in 0x0, 0x4, 0x8, or 0xC. For simplicity, I'll refer to this offset as A.

Now, we need to modify the routines to call this new code. There are two places to modify.

Code:

0x08030984: 00 48 00 47 xx xx xx xx

Code:

0x081368CC: 00 49 08 47 yy yy yy yy

The x's are A + 0x01, in reverse hex, while the y's are A + 0x35, also in reverse hex.

This affects the type icons on the party menu (as well as when learning a new move), and the type listed when selecting an attack.

This does not affect the type displayed by the TM Case. As that's not associated with a particular Pokemon, it just reads the type from the move data table. I actually suggest changing Hidden Power's entry in the table to be ???-type (change the byte at 0x08251722 from 0x00 to 0x09), so it will show as that in the TM Case, and the actual type everywhere else.

I didn't bother to force it to calculate and display the base power for Hidden Power, as I prefer the constant base power anyway, but if this was any indication, it would be pretty easy to do.

Check/Count a Specific Pokémon Species in the Party (FR/LG/Em)

So I'm not sure if there is a way to do this by scripting in these games, and I saw that trading-style thing post just a few above, but I wrote up a quick bit of ASM code to count the number of a specific species of Pokémon in the party, as a bit of practice for myself, and I thought I would share it.

The reason I wrote is so that it could be mainly used as a checkpartypokemon-like command in a script.

It works for FireRed and LeafGreen with no changes, works for Emerald by performing the changes given, and will probably work with any game as long as you find the matching offsets. ;)

Anyway, here's the ASM for FR/LG:

Code:

.text
.align 2
.thumb
.thumb_func
.global CountPartyPokemonSpecies

main:
	push {r0-r7, lr}
	mov r5, #0x0 @ This means fail
	ldr r6, var
	ldr r7, party_amount
	ldrb r4, [r7] @ Get Pokemon count from r7
	cmp r4, #0x0
	beq exit
	ldrh r3, [r6] @ Get the species to check
	cmp r3, #0x0
	beq exit @ Don't allow Missingno. This doesn't limit the species from going up, though.
	mov r7, #0x0
loop:
	ldr r0, first_pokemon @ Offset of first Pokemon
	mov r1, #0x64 @ Length of Pokemon RAM data
	mul r1, r1, r7 @ r7 holds current index
	add r0, r0, r1
	bl decrypt_poke_species @ Get this specific species.
	mov r9, r0
	pop {r0-r7}
	cmp r9, r3
	bne next
	add r5, r5, #0x1 @ Increase the counter
next:
	add r7, r7, #0x1 @ Increase party index
	cmp r7, r4 @ And compare against the number in the party
	blo loop @ I could use a bls here?
exit:
	str r5, [r6, #0x10] @ Store the result (r5) in r6 (the var -- 0x800D)
	pop {r0-r7, pc} @ Return

decrypt_poke_species:
	push {r0-r7}
	mov r1, #0xB @ This is the index for the Pokemon species.
	ldr r2, decrypt_poke @ Call the Pokemon decryption code
	bx r2
	
.align 2
party_amount:
	.word 0x02024029
first_pokemon:
	.word 0x02024284
var: @ Got this beauty from HackMew.
	.word 0x020270B8 + (0x8004 * 2)
decrypt_poke:
	.word 0x0803FBE9

And to work for Emerald, you need only change the end stuff:

Code:

.align 2
party_amount:
	.word 0x020244E9
first_pokemon:
	.word 0x020244EC
var: @ Got this beauty from HackMew.
	.word 0x020275D8 + (0x8004 * 2)
decrypt_poke:
	.word 0x0806A519

Some of it is based off some stuff from HackMew's Pokemon take away code, so yeah.

And of course, here's a sample script explaining how to use it:

Code:

#dynamic 0x800000

#include stdpoke.rbh

#org @start
lock
faceplayer
bufferpokemon 0x0 PKMN_MAGIKARP
setvar 0x8004 PKMN_MAGIKARP // Change this to the species you want
callasm 0x08XXXXXX // This is the offset of the routine + 1
compare LASTRESULT 0x1 // The count is stored in 0x800D
if B_>= goto @some // It will be 0 if there is none, or 1-6 for the count
msgbox @m1 MSG_KEEPOPEN // It also counts eggs, so yeah...
release
end

#org @some
buffernumber 0x1 LASTRESULT
msgbox @m2 MSG_KEEPOPEN
release
end

#org @m1
= You don't have any [buffer1]!

I hope someone finds this useful, even if for just an example for beginners to learn from.
Enjoy~! ^_^

EDIT: I added Emerald, although I didn't test it. ;)
EDIT 2: I tested the Emerald code, and it works. ^_^[/spoiler][/QUOTE]

    @NOTE: this function as it is appears at least 37 times BEFORE it does here in the Ruby ROM.  It appears even more often in Fire Red.  PLEASE, don't come to me saying that you found an equivalent offset claiming 20996 in AXVE equals E8C in BPRE.

it's just a matter of finding the rough same in fire red at the moment, specifically 20274. haven't even started on the other routine because all of this was really done this morning (shhhhhhh)

EDIT: accidentally disassembled the other routine referenced that we haven't found as well while disassembling what the first one references :P
coolio. meanwhile, i'm actually going to check out one of the other routines because really it doesn't seem equal ahaha

EDIT: ok i'm ****ing dumb

Code:

branch point AXVE:  
        20280
return point AXVE:  
        2028C (notice how it's literally branch +0xC)

branch point BPRE:  
        21CCE
return point BPRE: (one of what we're looking for)
        21CDA

return point 2 AXVE:
        202A0
return point 2 BPRE: (other of what we're looking for)
        21CE8

magically, when looking it up in IDB, almost everything matches! imagine that :):):):):):):):):):):):):)
here's bpre's routine, credits to andrea~ and the_learner (for making it relatively easy to find two addresses; he already found them). i did practically nothing except be stupid and look for something that was literally right under my nose the whole time
as usual, untested
