Todo_Door_Reset D037 LD A,$01 Writes $01 to the address contained at (depending on which door is currently being actioned);
Address Door
Door_Char_Buffer_01 Door 1
Door_Char_Buffer_02 Door 2
Door_Char_Buffer_03 Door 3
This is the first byte of character state data.
D039 LD L,(IX+$0A)
D03C LD H,(IX+$0B)
D03F LD (HL),A
D040 LD DE,$D2AD Writes Prep_Bandit_Draw_Close to the address contained at (depending on which door is currently being actioned);
