GBA ASM Programming

[Blah]

I have a problem with your first routine. Here's what I got https://i.imgur.com/obuckLm.png
My code:

Spoiler:

.align 2
.thumb
main:
push {r0-r1,lr}
ldr r0, pokemon_data
ldrh r0, [r0]
ldr r1, var
strh r0, [r1]
pop {r0-r1, pc}

.align 2
pokemon_data: .word 0x02024284 + 0x54
var: .word 0x20370D0

I also tried those ( 03 B5 02 48 80 88 02 49 08 80 03 BD 84 42 02 02 D0 70 03 02 ) assembled numbers and still got the same result. Why is this happening?

Hi. If I'm understanding this correctly, you're trying to check the Pokemon's level (hence 0x02024284 + 0x54) ? Well a Pokemon's level is 0-100, which can be represented in hex as 1 byte (0x64 being 100)

    ldr r0, pokemon_data
    ldrh r0, [r0]

You're loading a half word (2 bytes) which is going to load something extra as well. Try ldrb instead of ldrh.

That routine seems to be a failure. You're trying to load the level but you're loading a halfword (two bytes).
Change "ldrh r0, [r0]" to "ldrb r0, [r0]"

It worked perfectly. Thank you!

The link is broken, I'd love to try this out, could somebody post a working link or file? I'll give you my email if I have to.

To those talking about the broken link, I have a mirror for the compiler (but the compiler only):

I saw you asking for the compiler a lot of times in lot of threads so I got it for you.
get it from the attachment :)

Oh brother, the "ASM pack" has been removed from Dropbox. Where can I find this??

 

[Bnthomason]

Where do I find the Asm code? It's not on the page? Trying to understand asm as painless and easy as possible, but I can't find the asm code needed for this project... anyone have a backup?
