Help/Support Hacking VMOV.F64

[Ted2 39.2k iPhone 13 Pro 16.0 Donor]

So I've never worked with vectors, so I read @shmoo his tutorial on it. But I'm not sure what to do.

 

This is the code: 

VMOV.F64        D16, #2.0   <------->
STR             R0, [SP,#0x3C]
STR.W           R0, [R5,#0xCF4]
MOV             R0, #(cfstr_Acceleration_0 - 0x392CE4)
ADD             R0, PC  ; "acceleration"
STR.W           R0, [R5,#0xCBC]
VMOV            R2, R3, D16   ?????
LDR.W           R10, [SP,#0x98]
LDR.W           R0, [R11]
MOV             R1, R10
BLX.W           _objc_msgSend
MOV             R7, R7
BLX.W           _objc_retainAutoreleasedReturnValue

 

The one marked with <------> is the correct value, but I need to set it to like to #100+.

The one marked with ??? calls the VMOV.F64 (i think, it's the only function with D16 in it)

 

So how would I set the first function to #100?

 

Thankyou in advance!

Mod the VMOV.F64 D16, #2.0 to VMOV.F64 D16, #100.0

is the VMOV the starting of the function?

Yes
