• I reset the game to skip a logo. And I start the game.
• I create a Thief who has 18 Strength.
• I pick up the Thief and the Cleric who exists from the start of the game. and organize a party.
• I go to an elevator on B1F, and go down to B4F.
• I go to a room and beat a monster, and open a chest to trigger a Teleporter trap. The Teleporter brings me to the second elevator. I go down to B9F with the elevator.
• I encounter a group of monsters, because I was obliged to raise an alarm on B4F. But they are friendly, so I just leave without fighting.
• I go to a room and beat a monster by Cleric's dispell, and open a chest. A trap is Mage's Misery and it doesn't affect my party at all. I find a Epee of Excellence, a Ring of Movement, a Dagger of Thieves from the chest.
• The Thief equips the Epee of Excellence, and invokes the special power of Dagger of Thieves. Now, the Thief is a Ninja.
• The Cleric equips the Ring of Movement.
• I turn to south and encounter a group of monsters. I use Ring of Movement and teleport my party to the front of Werdna's room.
• I break into Werdna's room and surprise Werdna and his guests. The Ninja attacks Werdna and decapitates him. The Cleric dispells a Vampire Lord. And, at the next turn, the Cleric dispells a Vampire. Now, Werdna and his guests are beaten. I find the amulet!
• I use the amulet and teleport up 10 floors, and return to the castle. The Ninja is honored for recovering the amulet. The Cleric... oh, he is drowned in the castle moat :)

Basically, I manipulate luck by trial-and-error method. I let my bots generate random inputs, and bots continue the trials until they find the optimal solutions.

Lags often occur in this game because the random number affects the flow of codes. For example, when you go up/down to another floor, some lags can occur (probably, they are caused by the code initializing floor data). I tried avoiding lag as possible as I can, using bots.

In NES version, we can't create a Ninja/Lord at the start of the game. When we create a new character, we can get at most 29 extra points.

Teleporter never changes the floor. So I need a Ring of Movement to teleport to B10F.

The Ninja needs Epee of Excellence to hit Werdna. There is roughly a 2% chance that he decapitates Werdna with the weapon.

There is roughly a 5% chance that the Cleric dispells Vampire Lord or Vampire.

The Thief who exists from the start of the game is useless. To hit Werdna, the Ninja (changed from the Thief) must have 17 or 18 Strength and Epee of Excellence.

I don't touch the game switches. I think the wire-frame display would not be familiar to the users of NES version. And disabling music or sound would make the run tasteless.

That's why player's inputs affect the random number. Inputs of direction keys are processed in the NMI routine, and the needed clock cycles depend on whether a player made inputs or not. So the random number changes by player's inputs. But, the random number changes only a little by a input at one frame, so we often need to make inputs for a certain period to manipulate luck.
