Code working fine on dolphin, but crashing on wii

[jawa]

When loading a course on my wii with this code enabled, the game crashes. However, on dolphin, it runs just fine!
How do i fix that?
Code:
#address = 80590400
lfs f1, 0 (r31)
loc_0x0:
  lis r12, 0x8000
  ori r12, r12, 0x1D0
  lbz r10, 0(r12)
  cmpwi r10, 0x1
  beq- loc_0x1C
  b loc_0x34

loc_0x1C:
  .set GRAVITY, 0x40360000

  bl float

  .long GRAVITY

  float:
  mflr r11
  lfs f10, 0 (r11)
  lfs f13, -0x70 (r3)
  fmuls f13, f13, f10
  lfs f1, 0 (r31)
  fadds f1, f1, f13
