[ASM & Hex] Pokemon species

[feight0]

I want to just make a simple ASM where i put the index of a pokemon in the party into 0x8001 then i get the species of that pokemon written into 0x800D (or LASTRESULT), this is what i have:

.text
.align 2
.thumb
.thumb_func

main:
push {r0-r4, lr} @I'm using 4 registers, I think this should be enough
ldr r0, .SLOT @Load the index of the pokemon
ldrh r0, [r0] @change it into half-bite i think
mov r1, #0x64
mul r0, r0, r1 @change the index into a number we can handle
ldr r1, =(0x2024284) @load the pokemon data
add r0, r0, r1 @take the pokemon data at index in the party list
.... @need help here
ldr r4, .VAR @take 0x800D
str r0, [r3] @write the species to give that number back
pop {r0-r4,pc}


.align 2

.VAR:
.word 0x20270B6 + (0x800D *2) @change to any 2 byte free space in RAM
.SLOT:
.word 0x20270B6 + (0x8001 *2) @slot of Pokemon we want to check

From what I gathered until now I know that a pokemons Data structure has a Data part at offset 0x32 and that the species of the pokemon is at offset 0x0 of that Data. So in order to get that species I would need to just navigate to that offset. This code is probably not good, I tried my best by looking at other code in the ASM thread but I'm still a beginner. If someone has any idea how I can get the code to work pls respond and thank you in advance.

You don't need ASM to do this? special2 0x8001 0x147 will do pretty much exactly that: scan a party slot (0-5) read from variable 0x8004 and return that species ID to variable 0x8001.
Of course if you're doing it specifically to learn ASM then that's fine, but otherwise you're wasting your time

Thank you for your response. I was making another function but I thought maybe starting with something ez to learn ASM was better. Didn't know there was already a function.
