Bug: When playing in Free Mode in Chapter 3, "Azog the Defiler", if you skip the cut scene that shows Azog killing Thror, the next area where Thorin is supposed to battle Azog will not only show Azog completely missing but, none of his fellow Orcs will be there either. It will be a completely empty field. To make sure this doesn't happen, the entire cutscene must be viewed.
Bug: After about 10 minutes of gameplay, if you leave an area of the school and try to head to another, the screen will go black and the loading screen which shows a bubbling cauldron will appear. Unfortunately, the loading screen will not vanish but will remain. The only way to progress further if this bug occurs, is to reset the game console that this game is experiencing the glitch.
Bug: When attacking people in a restaurant, some of them that are sitting will slump over and 'die' with their heads on the table. Yet they are still alive in the game. But you can't lock on to them. You can't kill or hurt them ether. Blood splats, but nothing else. Punching, using melee weapons, shooting, using the chain saw, and even throwing grenades of other uses of explosives doesn't do a thing to them but splatter a little blood. Yet this supposedly 'dead' person will still talk to you if you bump them. Sometimes they'll still do the random compliment or insult and you can still have CJ respond to them.
Bug: After the S.S. Anne is gone, go to the guard that says that the ship is gone. After facing him, keep pressing right and then quickly push the START button. Save and reset. If everything's OK, you should continue facing right. Select a Pokémon that knows SURF and use this move. Instead of surfing to the right, you'll surf ON the guard! Press down twice, and you'll enter the S.S. Anne again.
Bug: If you drop paintbrushes out of your inventory, they float and are able to carry you on top of them, which you can do over and over to get really high on top of something.
Bug: If you fall in the water, your hat is temporarily removed, and when you go back to the surface, you have it on again. Well, if you get out of the water, and make Indy fall to the water just in the moment when he's putting his hat back on, it'll fall in the water and you can play the level with no hat.
Bug: There are certain parts of the game where you can play with the camera. In one of them, you can see through the Merchant's insides and you can see he's truly infected with Las Plagas! Watching him like this is really hilarious.
Bug: This glitch has been fixed in later versions of the game, but still works in the original NES version. When fighting the Yellow Devil, select your Elecbeam and fire it at the enemy's eye. As soon as you fire, start rapidly mashing the Select button over and over again as fast as you can till it hits. If done fast enough, the beam will instantly kill Yellow Devil in one hit.
Bug: On the road between Talewok or Gwernia and Erromon, there is an enemy rat that can cause the game to crash. When you come to the area with three signposts near a big lake, you're close to where he is. If you found this area earlier, it's the same spot where that hilarious cinema scene with the guy in the forest who was afraid of monsters occurred. Follow that path around the bend, through some pine trees, and you should come across a Giant Rat at the top of a hill. Try to avoid this enemy! Whenever I engage him, he causes the game to crash. I'm not kidding! The screen goes blank, and some text shows up and it actually says something like, "System Crash", and then some other text that makes no sense to me. My suggestion is to save near the signposts, then try to sneak past that enemy. If you engage him and nothing happens, don't worry about it. But if your system crashes, there IS another way to get to Erromon. You'll have to look for an opening in the wall along the road (you'll pass through some pine trees.) You should pass a treasure chest along the way. You'll emerge out onto a high plateau with another treasure chest. There's like a round, stony area in the middle of the plateau. You'll have to run down off of it and find the road. Continue taking the road West to Erromon.
Bug: When magnetic ceilings are found, and you fly towards the ceiling, while in midair, pause and take off the iron boots. You will be able to walk without iron boots.
Bug: In Hollow Bastion, right after you defeat the Maleficent Dragon and before you fight Riku/Ansem, during the movie scene where Sora sees Kairi on the ground in front of the keyhole in the hall containing the Princesses of Heart, Sora lifts Kairi and shakes her up and down to wake her up. The pendant on Kairi's necklace stays suspended in the air when he shakes her until the shot changes.
Bug: On the second floor of the house in Rangoon in which a man asks you to fetch his three llamas, you can walk through the right wall and walk around in the black border surrounding the room.
Bug: In the few instances where you can hit Marshal Jackson with the lightning cheat, he remains upright even after being depleted of his 2,500 life points. (I've tried that stunt in El Paso).
Bug: After getting all 120 stars and using the cannon to get to the top of the castle, if you walk around enough at the highest point you will fall through the roof and into a hidden dimension of the front wall. Going through the door itself will not let you escape, so you must jump through the wall to reach the outside.
Bug: In the Mars Lighthouse, in the same room you defeat the Flame Dragons in, return after you have defeated the Flame Dragons and fire off the cannon. A crack will appear where the ice was, even though there is no ice.
Bug: If you sprint forward, and then suddenly go backwards while pressing the button to crouch, the character should stay floating in the air somehow. You will move in slow motion, and when you reload, the character won't move a muscle.
Bug: In the England level when Alister and Zip are kidnapped, you can still hear Alister expressing his amazement over the headset when you perform a somersault.
Bug: When you get to the first downed life pod on the second level, if you park the warthog right at the top of the hill and get in the turret, when you look at the big structure, the landscape will change to a snow-covered hill that is a landscape from another level.
