i post the routine already compiled:

03 B5 05 48 00 88 05 49 41 43 02 48 40 18 80 21 01 70 03 BD B0 43 00 03 C4 E8 02 02 00 01 00 00

80 21

80 21 corresponds to our mov r1, # 0x80 then to change the status of the pokemon for example we have to change the byte 80 ^^

here we are given vary status byte:
addormentato: 01
scottatura: 10
congelamento: 20
paralizzato: 40

if you have problem, wrote in the comment ^^
