F641: Active Player Level
Used by the routine at PrintPlayerLevels.
Input
BC Player level as two digits
Calculate_ActivePlayer_Level F641 LD A,($5EA0) If ActivePlayer_Level is not FF jump to Calculate_Player_Level.
F644 CP $FF
F646 JR NZ,Calculate_Player_Level
F648 XOR A A=00.
This reads A into BC as two nibbles, e.g. level 21 would be 00010101 which returns 2101.
Calculate_Player_Level F649 CALL Convert_Base10 Call Convert_Base10.
F64C LD B,A B=A.
F64D AND %00001111 Keep only bits 0-3.
F64F LD C,A C=A.
F650 LD A,B A=B.
F651 RRA Rotate the bits of A right four times.
F652 RRA
F653 RRA
F654 RRA
F655 AND %00001111 Keep only bits 0-3.
F657 RET Return.
This entry point is used by the routine at PrintPlayerLevels.
Calculate_InactivePlayer_Level F658 LD A,($5EA4) If InactivePlayer_Level is not FF jump to Calculate_Player_Level.
F65B CP $FF
F65D JR NZ,Calculate_Player_Level
F65F XOR A A=00.
F660 JR Calculate_Player_Level Jump to Calculate_Player_Level.
