Help: RAM Write with ASM for a specific instruction

[Bully@Wiiplaza]

Hey,
it would be great if someone could provide me a RAM Write template for this instruction: lwzx rX, rY, rX!

For lwzx rX, rY, rZ the template would be:

Code Select Expand

lis rX, 0xVVVV
ori rX, rX, 0xWWWW
stwx rX, rY, rZ

But this time, the destination and source register is the same.

Thx for answers.

I just did a code for Lego pirates that was similar lwzx r0,r5,r0

li r12,-1
stwx r12,r5,r0
lwzx r0,r5,r0

lwzx r0,r5,r0

thx man, it´s short and simple! ;D
Works.

Code Select Expand


li r12,0x7FFF #new value
stwx r12,r4,r0
lwzx r0,r4,r0

generally:

Code Select Expand


lis r12, 0xVVVV
ori r12, r12, 0xWWWW
stwx r12, rY, rX
lwzx rX, rY, rX

cool. :eek:
