    The implementation of ROCK CLIMB in BPRE

    This post will only deal with the "rock climb" selected by the player in the pokemon selection scene, so please do the script on your own if you want to use rock climb by talking to a rock.
    This hack can judge the "playerfacing" and the number of the blocks you will climb.
    1. Firstly we will repoint and expand the RAM location for TMs: (found from Development: More TMs/HMs - The PokéCommunity Forums Credit goes to Taの境界)
    at 0x99E6A：
    Code: 
    01 48 00 47 00 00 FF FF FF 08
    FF FF FF 08 is the pointer to ram.asm (thumb mode +1)：
    ram.asm:
    Code: 
    .text
.align 2
.thumb
.thumb_func
.global tm_slots_hack

main:
ldr r0, ram
str r0, [r1, #0x18]
mov r0, #0x3B
strb r0, [r1, #0x1c]
ldr r0, return
bx r0

.align
ram:.word 0x0203c000
return:.word 0x08099e74+1
    0x203c000 is the free ram location.

    2. Use JPAN's save_block_hack to save properly.
    link: The PokéCommunity Forums - View Single Post - Research: FireRed Pokédex Hacking
    Or use the patch instead: JPAN's Save Block Patch for FR » Romhack.me - ROM Hacking Community

    3. tables and codes
    1)repoint the table at 0x45A76E, replace 0c 00 with the move id of rock climb (swapped), and put 0c 00 after it as the end. (special move table)
    2)repoint the table at 0x45A80C, add the move id (swapped). (TM table)
    3)repoint the table at 0x45A37C and add an pointer to the description text. Please make it short like other texts in this table. (description text pointer table)
    4)repoint the table at 0x45A618 and add [pointer to move name] A5 45 12 08 at the end of the table. (name_table)
    5)copy these data to 0x3D4D6C as item picture and palette data.
    Code: 
    C8 1C E9 08 64 1E E9 08
    (in item picture & palette table)
    6)copy these data to 0x3DEBCC as item data. (in item table)
    Code: 
    C2 C7 A1 AA FF 00 00 00 00 00 00 00 00 00 5B 01 00 00 00 00 E5 75 48 08 01 00 04 01 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
    Please edit the description pointer to your new description!
    7)edit the table at 0x252BC8 to enable some pokemon to learn the HM. This table is made up with bitfield, which means that you should convert it into binary to see the real data. 1 = learnable 0 = can't learn(TM learnable table)
    For example, data for bulbasaur is "20 07 35 84 08 1E E4 00"
    We divide it into 2 parts: "20 07 35 84" and "08 1E E4 00"
    Then swap them, so we get "84350720" and "00E41E08"
    Convert them into binary: "10000100001101010000011100100000" and "111001000001111000001000"
    get them together in the reversed order:
    "11100100000111100000100010000100001101010000011100100000"
    It's in the order of "HM08, HM07,.........,TM01"
    So if we want bulbusaur to learn HM09 we edit the higher part "111001000001111000001000"
    We change it into "100111001000001111000001000"
    Then we convert it into hexadecimal: "4E41E08"
    swap it to get "08 1E E4 04" and we absolutely use it to replace "08 1E E4 00".
    So you can see that we will always only deal with the higher part, I convert the lower part to just make things clearer

    8)repoint the table at 0x45A788 and add [XX XX XX 08 0D 00 00 00] to the end of it. (function table)
    XX XX XX 08 is the pointer to the following function: (thumb mode +1)
    check.asm: (main ROCK CLIMB function)
    Code: 
    .thumb
.align 2
push {r4, lr}

    change the 0x8kkkkkk & 0x8jjjjjj to the offset+1 of the following routines.

    code1：(get "playerfacing" in var_0x800C)
    Code: 
    .thumb

call_via_r2:
bx r2


call_via_r3:
bx r3

    change the "0x80" in code2 and check.asm to the behavior byte you selected for the "rock climb" tile block.

    4. fix the badge check routine so that it will check the 8th badge for the HM09 you added: (untested)
    place this at 0x12461C:
    Code: 
    00 48 00 47 MM MM MM 08
    MM MM MM 08 is the pointer to the following routine: (thumb mode +1)
    Code: 
    .thumb
.align 2
add r0, r4, #0
cmp r4, #7
blt checkbadge
mov r0, #7
cmp r4, #0xc
beq checkbadge
ldr r1, =0x8124627
add r1, #0x32
bx r1

checkbadge:
mov r1, #0x82
lsl r1, r1, #0x4
add r0, r0, r1
ldr r1, =0x8124627
bx r1

    5. An example: (Haven't edited the text and name yet)
    1_zpspkko0bn2.gif
    1_zpsdwugkkzw.png


    At last, I have to say that i haven't tried to teach the HM to a pokemon, so if there's any problem, simply follow a reply in Development: More TMs/HMs - The PokéCommunity Forums to delete the animation of learning TMs, but I think there's no problem)

    As you can see, I have done the main part, but I can't ensure there's no glitch in this hack. So please contribute to it! I'm so tired with it so i won't touch it recently...

    Edit: Here is a simple looping script to get all of the TMs and HMs as the cheats for the game won't work:
    Code: 
    #org @start
lock
faceplayer
setvar 0x8004 0x121
goto @snippet2

//---------------
#org @snippet1
release
end

//---------------
#org @snippet2
additem 0x8004 0x1
addvar 0x8004 0x1
compare 0x8004 0x15C
if 0x1 goto @snippet1
goto @snippet2

    Edit2: Source codes and binary files uploaded.

    Edit3: Corrected a slight typo. Codes reuploaded.
    But please pay attention that "8RRRRRR" & "8SSSSSS" are not in the attachment and they're shown as "8CCCCCC" & "8DDDDDD" in the files in the .zip archive so that they can be compiled successfully. If you don't understand, please simply follow the post and neglect the attachment. So is the offsets included in the script file (scr.rbc) because they use the offset in my test ROM XD

    Edit4: added explanation to bitfield.

    • Events that happen daily:



    First of all, this uses the Day/Night System's clock, or you can use ShinyQuagsire's RTC, which I'm fairly sure are one and the same anyway. Either way, you have to have that in the game or this won't work for obvious reasons.


    Insert this into free space.
    Code: 
    .thumb
start:
 push {r0-r7, lr}
 ldr r0, =(0x20370D0)
 ldrh r1, [r0]
 mov r2, #0x4
 mul r1, r1, r2
 ldr r0, =(0x3005546)
 add r0, r0, r1
 mov r1, r0
 mov r2, r0
 add r0, #0x1
 add r1, #0x2
 add r2, #0x3
 ldrh r3, [r0]
 ldrb r4, [r1]
 ldrb r5, [r2]
 ldr r6, =(0x300553C)
 ldrh r7, [r6]
 cmp r3, r7
 bcc x800D_1
 strh r7, [r0]
 ldr r6, =(0x300553F)
 ldrb r7, [r6]
 cmp r4, r7
 bcc x800D_1
 strb r7, [r1]
 ldr r6, =(0x3005540)
 ldrb r7, [r6]
 cmp r5, r7
 bcc x800D_1
 strb r7, [r2]
 ldr r0, =(0x20370D0)
 mov r1, #0x0
 strh r1, [r0]
 pop {r0-r7, pc}
x800D_1:
 ldr r6, =(0x300553C)
 ldrh r7, [r6]
 strh r7, [r0]
 ldr r6, =(0x300553F)
 ldrb r7, [r6]
 strh r7, [r1]
 ldr r6, =(0x3005540)
 ldrb r7, [r6]
 strb r7, [r2]
 ldr r0, =(0x20370D0)
 mov r1, #0x1
 strh r1, [r0]
 pop {r0-r7, pc}
    This hack uses variable x800D for almost everything. So each event that happens daily is supposed to have a number attached to it using x800D, like so.
    Code: 
    #dynamic 0x______
 
#org @start
setvar 0x800D 0x_ (set 800D to the table entry.)
callasm 0x8(offset where you put my the previous ASM +1)
compare 0x800D 0x0
if 0x1 goto @1 (if x800D is the value of 0, then the event has already happened today)
compare 0x800D 0x1
if 0x1 goto @2 (if x800D is the value of 1, then the event has not happened that day)
    Please credit if you use this, and report any bugs here or by PM/VM, thanks.


    ~EDIT~ It was pointed out to me that this doesn't work over save data outside of save states, that was an oversight. I'll fix it as soon as I can.

    Pre-battle Mugshot Hack in BPEE

    I don't hack Emerald but my friend jirachiwishmaker requested the code, so I will share it.
    This is a port of Jambo51's codes in this thread to Emerald Version
    If you still don't know what it is, please take a look at this picture:
    7-8_zpsiwx42jwk.png

    1. Make these byte changes:
    Code: 
    0x147C6A - 00 00 00 00 (disable the palette mixing)
0xB13FD - 78 (for safety's sake)
0x5C8F90 - CD 6A 0F 73 51 7B 93 7F D5 7F FF 7F (filling the palette...)
0x5C8F70 - CD 6A 0F 73 51 7B 93 7F D5 7F FF 7F
0x5C8F50 - CD 6A 0F 73 51 7B 93 7F D5 7F FF 7F

    2. Insert these 3 ASM codes in free space and change bytes accordingly:
    insert 00 48 00 47 AA AA AA 08 at 0xB0F44, in which AA AA AA 08 is the pointer to the following routine (thumb mode +1)
    Code: 
    .thumb
.align 2
ldrb r2, [r4, #7]
cmp r2, #0
beq normal
ldr r0, =0x80B0F5D
bx r0

normal:
ldrh r2, [r4]
lsl r0, r2, #2
add r0, r0, r2
lsl r0, r0, #3
add r0, r0, r1
ldr r1, =0x80B0F4F
bx r1

    insert 00 48 00 47 BB BB BB 08 at 0xB5E78, BB BB BB 08 = pointer to the following code (thumb mode +1)
    Code: 
    .thumb
.align 2
cmp r4, #0x47
beq normal
cmp r4, #0x48
beq normal
ldr r0, =0x2038BCA
ldrh r0, [r0]
lsl r5, r0, #2
add r5, r0, r5
lsl r0, r5, #3
ldr r5, =0x806E4C4
ldr r5, [r5]
add r0, r0, r5
ldrb r4, [r0, #3]

normal: 
add r5, r1, #0
add r6, r2, #0
mov r9, r3
ldr r7, [sp, #0x34]
ldr r0, =0x80B5E81
bx r0

    insert 01 49 08 47 00 00 CC CC CC 08 at 0x147C42, CC CC CC 08 = pointer to the following code (thumb mode +1)
    change 0x8FFFFFF to the palette table in your ROM and it can have 255 custom palettes.
    The table's structure is [pointer1][pointer2]........................
    Every pointer will point to a 16-color uncompressed palette (32 bytes)
    Code: 
    .thumb
main:
 ldr r1, ramoffset
 ldrh r1, [r1, #0x0]
 lsl r0, r1, #0x2
 add r0, r0, r1
 lsl r1, r0, #0x3
 ldr r0, trainertable
 ldr r0, [r0, #0x0]
 add r1, r0, r1
 ldrb r1, [r1, #0x1]
 cmp r1, #0x1f
 beq oldway
 cmp r1, #0x26
 beq oldway
 ldr r1, ramoffset
 ldrb r1, [r1, #0x7]
 sub r1, #0x1
 lsl r1, r1, #0x2
 ldr r0, table2
 add r1, r1, r0
 ldr r0, [r1, #0x0]
 b back
oldway: ldr r1, table
 mov r2, r8
 mov r3, #0x26
 ldrh r0, [r2, r3]
 lsl r0, r0, #0x2
 add r0, r0, r1
 ldr r0, [r0, #0x0]
back: ldr r1, return
 bx r1

.align 2
ramoffset: .word 0x02038BCA
trainertable: .word 0x0806E4C4
table:  .word 0x085C8FDC
table2:  .word 0x08FFFFFF
return:  .word 0x08147C51

    To activate it in a script, you can use this format:
    Code: 
    trainerbattle 0(type, you can change it to fit your script) 0x50(your chosen trainer's ID) [b]0x0100[/b] @pointertomsg1 @pointertomsg2
    0x0100 means the first palette in your custom table at 0x8FFFFFF, and 0x0200 means the second, ...... 0xff00 means the 255th palette.

    Some sample palettes in the original game: (If you don't change the tiles and tileset, please build your palette in this format using APE)
    Code: 
    D5 18 CE 39 52 4A D6 5A 5A 6B 17 5C 59 64 9B 6C DD 74 1F 7D CD 6A 0F 73 51 7B 93 7F D5 7F FF 7F
    Code: 
    D5 18 CE 39 52 4A D6 5A 5A 6B 41 07 A4 13 C6 1B E9 27 EF 3F FC 45 3E 4E 7F 56 BF 5E FF 66 FC 45
    Give credit to Jambo51 (for the routines for BPRE) and jirachiwishmaker (for finding some offsets) if you use this hack. I only adjusted the routines so that it will be compatible with Emerald's RAM structure and fixed a small glitch in Jambo51's code1. So no credit needed for me, if you don't want to make your credit list long.

    insert 01 49 08 47 00 00 CC CC CC 08 at 0x147C42, CC CC CC 08 = pointer to the following code (thumb mode +1)
    change 0x8FFFFFF to the palette table in your ROM and it can have 255 custom palettes.
    The table's structure is [pointer1][pointer2]........................
    Every pointer will point to a 16-color uncompressed palette (32 bytes)
    Code: 
    .thumb
main:
 ldr r1, ramoffset
 ldrh r1, [r1, #0x0]
 lsl r0, r1, #0x2
 add r0, r0, r1
 lsl r1, r0, #0x3

 bx r1

.align 2
ramoffset: .word 0x02038BCA
trainertable: .word 0x0806E4C4
table:  .word 0x085C8FDC
table2:  .word 0x08FFFFFF
return:  .word 0x08147C51

    To activate it in a script, you can use this format:
    Code: 
    trainerbattle 0(type, you can change it to fit your script) 0x50(your chosen trainer's ID) [b]0x0100[/b] @pointertomsg1 @pointertomsg2
    0x0100 means the first palette in your custom table at 0x8FFFFFF, and 0x0200 means the second, ...... 0xff00 means the 255th palette.

    Some sample palettes in the original game: (If you don't change the tiles and tileset, please build your palette in this format using APE)
    Code: 
    D5 18 CE 39 52 4A D6 5A 5A 6B 17 5C 59 64 9B 6C DD 74 1F 7D CD 6A 0F 73 51 7B 93 7F D5 7F FF 7F
    Code: 
    D5 18 CE 39 52 4A D6 5A 5A 6B 41 07 A4 13 C6 1B E9 27 EF 3F FC 45 3E 4E 7F 56 BF 5E FF 66 FC 45
    Give credit to Jambo51 (for the routines for BPRE) and jirachiwishmaker (for finding some offsets). I only adjusted the routines so that it will be compatible with Emerald's RAM structure and fixed a small glitch in Jambo51's code1. So no credit needed for me, if you don't want to make your credit list long.

    Pre-battle Mugshot Hack in BPEE

    Click to expand...

    Still don't get the mugshot. I have inserted the routines and done the byte changes correctly but still the mugshot do not appear. Assuming I have modified the script too.

    EDIT: It works fine when I use 0x0001, 0x0002, and so on. 0x0100, 0x0200, and so on which are standards to be used for mugshots do not activate well unless you have a palette on that 0x100 slot.

    Sorry, I've corrected routine 1 & routine 3... Now it should work fine with 0x100, 0x200, ... ,0xff00

    Please look at following words if you want the custom moves!!!
    Firstly to use custom moves you need a routine written by FBI and modified by me which was originally posted here:
    Code: 
    0x3EA46 - 01 48 00 47 00 00 XX XX XX 08 //hook
    and XX XX XX 08 points to (+1):
    Code: 
    0C B4 1B 48 1B 49 00 F0 21 F8 0C BC 00 28 1E D0 16 4D 00 24 29 1C 09 78 00 29 13 D0 02 21 61 43 49 19 09 88 40 46 14 4B 00 F0 1D F8 01 34 04 2C F0 D1 00 04 49 46 0D 0C 00 9B 10 49 48 45 05 D1 0F 49 08 47 0C 4B 00 F0 0E F8 F2 E7 08 47 40 46 21 1C 00 93 10 B4 08 4C 00 F0 06 F8 10 BC 00 04 49 46 0D 0C 07 4B 18 47 20 47 C0 46 BE 70 03 02 [FF 40 00 00] (Here means var 0x40ff) 69 E5 06 08 B1 E8 03 08 61 EA 03 08 57 EA 03 08 51 EA 03 08

    How to use:

    Code: 
    lock
faceplayer
setvar 0x40ff 0x1 //custom move trigger
setvar 0x8000 0x19A //species
setvar 0x8001 0x28 //level
setvar 0x8002 0x8F //item (This won't work, so you can't make the pokemon hold an item because another routine clears it. I don't know the reason and I can only wait for fixing. )
setvar 0x8003 0x1 //moves
setvar 0x8004 0x2
setvar 0x8005 0x3
setvar 0x8006 0x4
setvar 0x8007 0x1F //max IVs
setvar 0x8008 0x1F
setvar 0x8009 0x1F
setvar 0x800A 0x1F
setvar 0x800B 0x1F
setvar 0x800D 0x1F
setvar 0x800F 0x1 //shiny
callasm 0x8MMMMMM //offset of the ASM function +1
dowildbattle
setvar 0x40ff 0x0 //make it normal
release
//Here you can insert other codes. 
end

    The item will be cleared by another routine (around 0x44446), so I hope that someone can fix the bug to make the routine more perfect. :)

    Pokemon Obedience via Level and Happiness!


    How it works:
    If your Pokemon outlevels the level your badges say you can control, it will disobey you if it's unhappy. The concept was pretty simple sounding, but there was a lot of work that went into it. This should keep some similarities to the anime.
    I should note that if your Pokemon loves you, and you don't have the badge to train it, it will still listen to you :3

    This one is called love.asm

    How to insert:
    Compile and insert into freespace the following code:
    Spoiler:

    Here's a compiled version:
    Code: 
    82 24 24 01 00 22 20 1C 15 4E 00 F0 28 F8 01 28 04 D1 01 34 01 32 08 2A 1A D0 F4 E7 0A 20 82 22 12 01 A4 1A 44 43 14 34 28 88 78 43 0D 4E 80 19 38 21 0D 4E 00 F0 13 F8 A0 42 09 DD 28 88 78 43 08 4E 80 19 20 21 08 4E 00 F0 09 F8 7F 28 01 D9 01 20 01 E0 05 48 00 47 00 22 05 49 08 47 30 47 D1 E6 06 08 84 42 02 02 E9 FB 03 08 15 D4 01 08 2B D4 01 08
    Navigate to 0x1D3E0 and insert:
    Code: 
     00 48 00 47 XX XX XX 08
    Where XX XX XX is the reverse hex pointer to location you compiled the routine.

    I should mention there was a little bit of this routine which I'm skipping over. Basically it checks if the Pokemon is a Mew or Deoxys. It then checks if the Mew/Deoxys has it's obedience set. I find the need for this non-existent because the obedience is checked by happiness and badges my way. In the end, if you want to keep these two (rather pointless) checks, insert at 0x1D406.

    Sorry for the double post. I want to keep my routines on separate posts to help in formatting the first post's index :x

    Requested here: http://www.pokecommunity.com/showpost.php?p=8510180&postcount=1
    I made a special exception and decided to do it for her here by that I mean no other requests were on the table:)

    Hi, a completely noob in this type of scripts here.
    I just wanted to know how can i properly insert this Script because i obviously don't know how and because there isn't any cheat to make the Pokemons obey xD

    I tried to insert it it like this:
    1) Searched for a Free Offset in FSF, in the amount of bytes typed 256
    2) Went there in HxD and pasted the whole compiled script which you posted ("82 24 24 01 00 22" etc, etc)
    3) Went in HxD to 1D3E0 and then typed the pointer offset from FSF
    4) Saved, tried the ROM and then since the first second there was just a white screen

    Once again, this is the first time i ever try to insert an ASM script in a ROM, so please, try to not kill me xD ..

    EDIT:
    Nvm, reading FBI's guide to insert them, wish me luck.

    EDIT2:
    Okay, so, i copied the whole code into the
    Code: 
     tags, pasted it in a Txt file and saved it as "Love.asm" ([COLOR=Gray]replacing the .txt atribute[/COLOR])
Then, i've dropped the Love.asm to the thumb.bat and there's supposed to be a "Love.bin" file over there, which isn't :/
I'll try to compile it via CMD just like the tutorial says and see if it works that way, but in my 2nd try it didn't..

EDIT3:
Okay, trying to compile it via CMD it says:
"love.asm:0: Warning: end of file not at end of a line: newline inserted
Assembled successfully"
So.. i'll take that warning as a false alarm, i'll try to insert it in the ROM, wish me luck.

EDIT4:
Welp, didn't worked.
Opened in HxD the file "Love.bin", copied the whole thing, pasted it in an empty offset ([COLOR=Gray]82B31C[/COLOR])
Then, went to 1D3E0 and typed "00 48 00 47 1C B3 82 08"
Saved, went to a sign with a simple msgbox, typed the command "callasm 0x82B31D" just before the "end", compiled in XSE, put its offset in the sign's one at A-Map, and when i was about to test, there's just a white screen the whole time :c ...
I'm obviously doing something wrong, but a clue would be really appreciated u.u

EDIT5:
Okay, i somehow managed to insert it more correctly, but now, when i'm about to choose an attack, the game freezes ;_; ..
Is the whole thing compatible with Fire Red? xD

Mother of notifications I got from this post, lol. I think this specific routine is working, I've tested it a while ago when I was making it.

You don't use callasm, just use the compiled code snipplet, and paste it into some free space. From there you make a reverse hex pointer and place the hook at 0x1D3E0, then don't touch it, it's automated. If you're still having issues, please open your ROM in VBA -> disassemble -> (tick thumb) and in the goto space put in 0801D3D0. Print screen and paste the result in the ASM help thread or something. I'll assist with specific problems over there.

    Events that happen daily:



    First of all, this uses the Day/Night System's clock, or you can use ShinyQuagsire's RTC, which I'm fairly sure are one and the same anyway. Either way, you have to have that in the game or this won't work for obvious reasons.


    Insert this into free space.
    Code: 
    .thumb
start:
 push {r0-r7, lr}
 ldr r0, =(0x20370D0)
 ldrh r1, [r0]
 mov r2, #0x4
 mul r1, r1, r2
 ldr r0, =(0x3005546)
 add r0, r0, r1
 mov r1, r0
 mov r2, r0
 add r0, #0x1
 add r1, #0x2
 add r2, #0x3
 ldrh r3, [r0]
 ldrb r4, [r1]
 ldrb r5, [r2]
 ldr r6, =(0x300553C)
 ldrh r7, [r6]
 cmp r3, r7
 bcc x800D_1
 strh r7, [r0]
 ldr r6, =(0x300553F)
 ldrb r7, [r6]
 cmp r4, r7
 bcc x800D_1
 strb r7, [r1]
 ldr r6, =(0x3005540)
 ldrb r7, [r6]
 cmp r5, r7
 bcc x800D_1
 strb r7, [r2]
 ldr r0, =(0x20370D0)
 mov r1, #0x0
 strh r1, [r0]
 pop {r0-r7, pc}
x800D_1:
 ldr r6, =(0x300553C)
 ldrh r7, [r6]
 strh r7, [r0]
 ldr r6, =(0x300553F)
 ldrb r7, [r6]
 strh r7, [r1]
 ldr r6, =(0x3005540)
 ldrb r7, [r6]
 strb r7, [r2]
 ldr r0, =(0x20370D0)
 mov r1, #0x1
 strh r1, [r0]
 pop {r0-r7, pc}
    This hack uses variable x800D for almost everything. So each event that happens daily is supposed to have a number attached to it using x800D, like so.
    Code: 
    #dynamic 0x______
 
#org @start
setvar 0x800D 0x_ (set 800D to the table entry.)
callasm 0x8(offset where you put my the previous ASM +1)
compare 0x800D 0x0
if 0x1 goto @1 (if x800D is the value of 0, then the event has already happened today)
compare 0x800D 0x1
if 0x1 goto @2 (if x800D is the value of 1, then the event has not happened that day)
    Please credit if you use this, and report any bugs here or by PM/VM, thanks.

    Hi, I have a problem with this. The timed events are all working fine until I save and reload the game. It seems once you reset the game and continue from your save that the event shows as 'not happened' despite the day being the same as when I first activated the script. I think this is a bug. Is there any workaround?

    I use savestates because I don't quite trust the save data fixes that other people have provided. Savestates definitely work, but I hadn't tested that with regular saves. It was an error on my part to overlook that other people would use the regular save function. If possible, I'll come up with another routine that'll do the same thing but be incorporated to the regular save data.

    Reusable TMs in LeafGreen

    First posted by FBI here, these routines prevent the consumption of TMs like in the recent games.

    Prevent Consumption:
    0x124F50: 00 00 00 00
    0x125C58: 00 00 00 00
    0x124E84: 00 00 00 00

    Make it Ungivable:
    0x132690: 00 00 17 E0

    Make it Unsellable:
    0x1328FC: 00 00 00 00

    To remove the quantities showing up in the bag:
    Code: 
    .text
.align 2
.thumb
.thumb_func

main:
	cmp r5, #0x0
	bne end
	ldr r3, =(0x8131ED6 +1)
	bx r3

end:
	mov r0, r7
	mov r1, #0x8
	mov r2, r4
	ldr r6, =(0x8133588 +1)
	bl link
	ldr r3, =(0x8131ED6 +1)
	bx r3

link:
	bx r6

.align 2

    At 0x131ECC put:
    00 48 00 47 XX XX XX 08
    Where XX XX XX is the pointer to where you assembled the routine + 1.

    Finally at 0x131E7D change the byte to E0.

    Random Natural Number Generator in LeafGreen

    A port of FBI's Natural RNG, this was almost exactly the same. Just needed one offset changed.

    Compile and insert this routine anywhere.
    Code: 
    text
.align 2
.thumb
.thumb_func

main:
	push {r4, lr}
	ldr r4, =(0x08044EC8 +1)@gen random number
	bl linker
	lsl r0, r0, #0x10
	lsr r0, r0, #0x10
	ldr r1, =(0x020370B8) @convert to int between 0x0 to [var 0x8000] exclusive
	ldrh r1, [r1]
	ldr r4, =(0x081E4660 +1) @ this changed
	bl linker
	ldr r1, =(0x020370D0) @store in last result
	strh r0, [r1]
	pop {r4, pc}

linker:
	bx r4

.align 2

    To use it, set variable 0x8000 to the number of results you want, and it will generate a number between 0 and 0xFFFF exclusive. The result will then be placed in variable 0x8000.

    Reusable TMs in LeafGreen

    As part of an effort to encourage LeafGreen hacking, I've decided to begin translating various ASM routines from FireRed to LeafGreen. I decided to start with reusable TMs. First posted by FBI here, these routines prevent the consumption of TMs like in the recent games.

    Prevent Consumption:
    0x124F50: 00 00 00 00

    ldr r3, =(0x8131ED6 +1)
    bx r3

end:
    mov r0, r7
    mov r1, #0x8
    mov r2, r4
    ldr r6, =(0x8133588 +1)
    bl link
    ldr r3, =(0x8131ED6 +1)
    bx r3

link:
    bx r6

.align 2
    At 0x131ECC put:
    00 48 00 47 XX XX XX 08
    Where XX XX XX is the pointer to where you assembled the routine + 1.

    Finally at 0x131E7D change the byte to E0.

    Oooh~ This is cool! I remember that I chose LeafGreen above FireRed when I was a kid to be my first GBA game! Oooh~ The feels of nostalgia. T^T But you should have used and ported this one instead. It doesn't require a different routine, just a few byte edits, which I think is more practical. Just sayin'. :P

    Pokemon_XY said:
    I've found a way to make TMs unsellable:
    Code: 
    0x132924 - 00 00 00 00
    In addition, the quantity in bag when you buy TMs in the game should be hided, and here is a quick way to remove the box which shows the quantity for all items:
    Code: 
    0x9BCC2 - 00 00 00 00
    So here's the full code, no extra routines needed

    Reusable TMs

    Code: 
    0x1326BA - 17 E0 //can't hold as item
0x124F78 - 00 00 00 00 //can't delete
0x125C80 - 00 00 00 00 //can't delete
0x124EAC - 00 00 00 00 //can't delete
0x131EA6 - 2A E0 //fix the graphic
0x132924 - 00 00 00 00 //can't sell
0x9BCC2 - 00 00 00 00 //hide the box showing quantity

    I know we're already out-of-topic, sorry for that but :

    What is the point of hacking LG ? It's a waste of time.

    We should put all our effort together by hacking EM or FR to make more progress, there's no point on hacking LG/RUBY/SAPPHIR because they don't bring anything new/better while FR/EM have so much research done.

    Please don't tell me there's nothing to hack in these games anymore. There's plenty of things to do.

    Of course anyone can do whatever he wants, but for the sake of the hacking and the progress, we shouldn't encourage to hack other games than FR and EM

    • Meh, no one really cares. He just ported the stuff over, which is completely fine in my eyes. Lets let the folks hack what they wanna hack, sure some ROM bases are inferior, but if you don't care then whatever. I mean, all gen 3 ROMs are superior to gen 2 and 1 ROMs interms of coding and implemented features, yet people still hack those.

    EDIT: I lied, early gens have complete disassembly. Sorry folks :D
