  1. It's not a script.
  2. I don't change anything, I just assign a values for both. Pretty different.
  3. You should read the tutorial again, I guess.

it is A instead of C right?
I did something wrong though the script freezes before the guy even faces player
which is weird cuz i called the asm after faceplayer, then called buffernumber 0x1 LASTRESULT (for the secret id) and buffernumber 0x2 (for the trainerid)
the music keeps playing so i think it's my problems with asm.
well anwyays here's my attempt for FireRed.
Spoiler:

.text
.align 2
.thumb
.thumb_func
.global lesson1

main:
push {r0-r1, lr}
ldr r0, .PLAYER_DATA
ldr r0, [r0]
ldr r1, .VAR
ldrh r0, [r0, #0xC]
strh r0, [r1]
pop {pc}
push {lr}
ldr r0, .PLAYER_DATA
ldr r0, [r0]
ldr r1, .VAR2
ldrh r0, [r0, #0xA]
strh r0, [r1]
pop {r0-r1, pc}

.align 3
.PLAYER_DATA:
.word 0x02024EA4
.VAR:
.word 0x0201E8C2 + (0x800D * 2)
.VAR2:
.word 0x0201E8C2 + (0x8001 * 2)

i haven't tried debugging it just yet....
Yes, it's 0xA instead of 0xC as it's 2 bytes before. Aside from that, your whole ASM routine is screwed up. Please read the guide again, as I never used .align 3 anywhere, for example. Your push/pop usage is also wrong.

I used the right offset (0x820000), it had plenty of free space, and yet nothing worked and my ROM got screwed up... And yes, I did assemble the fr lesson, I double checked it.
That's just because you screwed up your ROM. Remember you can't simple insert the new routine pasting it somewhere. That way, you increase the ROM size and screw up all the data after because the pointer will be mostly broken. So, when pasting, make sure to overwrite the right amount of space.
