Official SRS

Tetris Worlds and Tetris DS are based on the Tetris Guideline, including SRS. They have the following behavior:

iiii

Rotated left

i
giss
gissjjj
gij

Soft dropped

gss
gssjjj
giiiij

Rotated right

But the wall kicks are not symmetric, as TW and TDS prefer to kick up rather than down when rotating left:

iiii
zzt
lllzztt

i

i
zzt
lllzztt

Rotated right

i
zzit
lllzzitt
lit

Soft dropped

iiii
zzt
lllzztt
lt

Rotated left

However, an extra block impedes the choice of the upward kick position:
