What about VLDRs?

you can just move values into the register being loaded. Because really all a VLDR is doing is loading a value, so moving a value into the register is the same thing to a computer

 

For example

VLDR S3, [R4, #0x38C]

can be changed to 

VMOV.F32 S3, #20.0 <--- this 20 can be anything you want in the limit of [-31.0,31.0]

I tried that and game crashed (probably NPC then?). Had one last question. What is DCFS?

Thanks a lot :D
