I've noticed this game tries to write to the hardware vectors, which I'm certain is a bug.

Any idea what the first part of this code is supposed to do? Going by the PRM, it's reading the 3rd byte of the Winchester size, but I'm fairly certain it's meant to read something else:

MOV R0, #&A1
MOV R1, #&BF
SWI XOS_Byte
ADR R1,&8F14
STR R2,[R2,#1]
STR R2,[R2,#2]

MOV R0,#&15
SWI XOS_Word
MOV R0,#&100
SWI XExS_MusicFade
