SMS (Store to raM Short address) is a Super FX instruction that stores a value to the Game Pak. The bank must be specified with RAMB.

Let:

R11 = abcdh
RAMBR = 71h

After executing this program:

 Syntax              Opcode
 SMS (194h), R11     3e ab ca

We have:

(71:0194h) = cdh
(71:0195h) = abh
