56361 OR A
56362 RET Z Decrease *EventTimer by one.
56363 DEC A
56364 LD (25759),A
56367 OR A Return if the timer is still running.
56368 RET NZ Jump to Dispatch_Events with *PendingEvent.
56369 LD A,(25760)
56372 JP Dispatch_Events
This entry point is used by the routines at Handler_MovingObjects and Handler_Enemies.

56379 XOR 255
56381 LD (IX+9),A
56384 LD A,(IX+8)
56387 DEC A Return if the vertical delta is now zero.
56388 XOR 255

Pause_LeavingRoom 56403 PUSH AF Stash AF on the stack.
56404 LD A,(25762) Jump to Pause_LeavingRoom_Done if *CurrentRoom is zero.
56407 OR A
56408 JR Z,Pause_LeavingRoom_Done
56410 LD BC,1000 Call JumpTable_Delay with a pause of 1000.
