Now, to jump to the toilet-display routine even in "Master Bedroom",
we'd have to replace these two RET instructions with jumps to 38298.
Unfortunately a RET instruction is one byte long, while a JR
instruction is two bytes long (the second byte is the operand that
tells it by how many bytes to jump forwards/backwards, as a signed
value from -128 to +127). So to make this change would entail
shunting and relocating of code.
Beg to differ. All you need is a little spaghetti.
9539 20 -> 18
9567 B7 -> B6
959A 3A -> C0
959B 20 -> CD
959C 84 -> 3B
959D FE -> 95
959E 21 -> 00
959F C0 -> 00
