Coding Questions and other Quandaries

[Vega]

At first glance, you can chop down the source to something like this. Btw I have no idea what any of the checks are for. I don't own the game and have never made codes for it.

lbz r4, 0x7 (r31)
lis r12, 0x803A

cmpwi r4, 0
lhz r11, 6862 (r12)
beq- check_bit_19
cmpwi r4, 1
lhz r11, 8262 (r12)
beq- check_bit_19
cmpwi r4, 2
lhz r11, 9662 (r12)
beq- check_bit_19
cmpwi r4, 3
lhz r11, 11062 (r12)
bne- original_instruction

check_bit_19:
cmpwi r11, 0x1000 #Considering this appear to be a bit check, I would try to use andi. instead
bne- original_instruction #If using andi. switch this to beq-

mr r4, r0
addi r4, r4, 1 #Instead of doing addi, there may be a way to implement subic. with a free check against 0 due to record bit usage. Retweak rest of code for check against 0 instead of seven.
cmplwi r4, 7
ble- store_it

li r4, 0

store_it:
stw r4, 5344 (r31)

original_instruction:
lwz r4, 5344 (r31)

NOTE: On the discord screenshot you gave me, the source doesn't use the actual original instruction. The original instruction uses r3 as the source register, not r31.
