| 8167 | CP (IY+$0F) | Is is the current room for the current character? | ||
| 816A | JR Z,$8175 | Jump forward if it is. | ||
| 816C | LD A,(IY+$0F) | Otherwise copy the current room to the demo mode room flag. | ||
| 816F | LD ($813A),A | |||
| 8172 | CALL $B952 | Draw the room. | ||
| 8175 | CALL $81AE | Move everything on screen. | ||
| 8178 | XOR A | Read all keys. | ||
