Brief Intro
Here I've got a couple of routines for you. They are designed to get the minimum and maximum levels respectively.
Description
As you can see, the routines are pretty short and simple so I did not comment them on purpose.
Either way, here's a brief description of what happens:
- Get the Pokémon party level address into r1.
- Load the first value into r0, and assume it's the minimum (or maximum) value yet.
- Loop 5 times, and update the mininum (or maximum) value if needed.
- Get the LASTRESULT var address into r1 and store the minimum (or maximum) level.
The minimum routine, however, is slighty different because a zero-level is not an acceptable value so there's an extra check to take that into account (otherwhise as long as your team is not full, the minimum level would always be zero, which is no good obviously). That also means the routine will loop up to 5 times rather than always 5 as it happens in the maximum routine.
The Code
GetMinPartyLevel
- FireRed/LeafGreen
Code:
.text
.align 2
.thumb
.thumb_func
.global GetMinPartyLevel
main:
push {r0-r3, lr}
ldr r1, .PARTY_LVL
ldrb r0, [r1]
mov r3, #0x5
loop:
add r1, #0x64
ldrb r2, [r1]
cmp r2, #0x0
beq return
cmp r2, r0
bge next
add r0, r2, #0x0
next:
sub r3, #0x1
cmp r3, #0x0
bne loop
return:
ldr r1, .VAR
strh r0, [r1]
pop {r0-r3, pc}
.align 2
.PARTY_LVL:
.word 0x02024284 + 0x54
.VAR:
.word 0x020270B6 + (0x800D * 2)
- Ruby/Sapphire
Note: The routine is the same as the FR/LG one; just replace the bottom part with the following:
Code:
.align 2
.PARTY_LVL:
.word 0x03004360 + 0x54
.VAR:
.word 0x0201E8C2 + (0x800D * 2)
- Emerald
Note: The routine is the same as the FR/LG one; just replace the bottom part with the following:
Code:
.align 2
.PARTY_LVL:
.word 0x020244EC + 0x54
.VAR:
.word 0x020275D6 + (0x800D * 2)
