Help/Support Return true in armv64 & bx lr

[Ted2 39.2k iPhone 13 Pro 16.0 Donor]

Hey,

 

So in armv7 I had this code:

PUSH            {R4,R5,R7,LR}
ADD             R7, SP, #8

I changed it to

MOV R0, #1

BX LR

 

Now I wanted to do this on amrv64 too,

So I looked up some tutorials & I thought this would be the right code to do:

MOV W0, #1

RET

This crashed the game once I selected the item.

MOV X0, #1

RET

This didn't had any effect.

 

Anyone knows what I do wrong?

 

Thankyou in advance!

Why would that return to true?

Wouldn't that skip the whole function?

find CMP and change 1 to 0 

1 = true   

0 = false

CMP ============ #0
or
CMP ============ #1
