Plot hole: Level Five: After finishing the mission to defeat The Dirty Bubble atop the Sea Needle, the game completes, the Dirty Bubble is stopped and Bikini Bottom is saved from the little dirty bubbles infecting them. After saving the day, the game lets you go back to Bikini Bottom to finish off some other missions, but despite this the citizens are still infected by the little dirty bubbles and if you go back to the Sea Needle, the Dirty Bubble is still waiting there and reading to be battled again.
Bug: Kashyyk Training: If you get smashed by one of the logs whilst training, you go straight through the log.
Factual error: On the Solar level, the other Star Fox team members only take damage from heat while they are talking. Being on the Lylat System star, they would be constantly taking heat damage just like Fox.
Bug: Not sure if this can be done on today's consoles but, this could actually be accomplished on the original NES. Two controllers must be plugged into the NES. Take a heavy item [i.e. A book or stapler.] and place it on the right directional button on the second controller and keep it there. Next, fall into a pit and wait for an enemy to go over the pit. When this happens, Megaman's energy will be completely depleted. After that happens, press the jump button on the first controller and Megaman will jump out of the pit and will now be invincible throughout the rest of the level as long as the right directional controller on the second stays pressed down. Note: this will only work when playing the first part of the game which involves Dr. Wily's minions but, won't work when the player makes it to Dr. Wily's lair.
Other mistake: In the opening sequence, Dr. Wily's name is misspelled Dr. Willy with two L's as Base's container is opening. This mistake is carried over to Mega Man Legacy Collection 2.
Audio problem: Several lines in this game are said where the character's mouth is out of sync for at least a third of the line. Especially Doc's lines.
Character mistake: When Fatman begins to explain the 'party' rules, he says "If you prefer to stay in ONCE piece..." This is a spelling error, as he should have said 'ONE piece'.
Continuity mistake: In the original Xbox version, after retrieving Jagger Valance's package and giving it to him, he tells you how to escape from Butcher Bay. After he does, kill him. Later in the game, after making it to the Space Port, a ship will be there waiting. When entering the ship, Jagger Valance will be there attempting to open the door to the cockpit.
Bug: If an NPC zombie is too close to certain obstacles, they will appear to be crouched on the ground. The Collision is just enough to cause them to not be able to make any sideways movement unless they are activated, thus they will just be crouched on the ground slowly rotating around. It is comical for a group of zombies to be doing this while occupying the same space, as they have a dog pile effect making a tower of crouched rotating zombies.
Other mistake: Kaiser-Friedrich Museum: At the beginning on the bridge you see several Russian soldiers. The ones just walking idly about on the bridge seem to be blind idiots. They just run into things causing collision and so, they just stand there walking in place against obstacle. Sometimes they turn a bit and keep walking until they hit the next obstacle.
Other mistake: When Set takes control of a robot, he uses it to grab and pick up Frau Engel by her face causing damage. When Frau Engel stands up and looks directly at Blazkowicz, her bottom jaw is dislocated and most of her lips have been torn off, making talking impossible. But, when she threatens Blazkowicz, she is speaking in completely coherent sentences.
Bug: In this game, unlike the sequels, the CPU players will go after any item that spawns with reckless abandon. If there are just two level 9 CPU players on the stage, and an item spawns, they will both go for it. If they are equal or approximately equal distance from it on opposite sides, they will steadily walk towards it. Once they get within a certain distance of each other, their Level 9 defense programming kicks in, and they will shield roll past each other, and the item. Get up, and do it again, and again, and again bringing the fight to a standstill until the item fades away.
Continuity mistake: At the end of the Crossroads level you are at a corner building. During the battle a tank comes and shoots at the building in which you exit the building through a doorway that had planks boarded to it. During the ending cutscene you are in the building again and in the background you can see the doorway with planks boarded to it.
Other mistake: Playing Spain in this game gives you a bonus to attack Indian villages, however, actually attacking Indian villages lowers your overall score.
Factual error: Paul Chuck talks a lot about how good Lammy's guitar is going to be, because of the wood they make it out of. However since it is an electric guitar the shape and material of the body would not actually make any difference to the sound.
Bug: When taking off in the glider with the tow-plane, if you are using the virtual cockpit view, you can see the tow-rope through the glider instrument panel.
Continuity mistake: When Anderson is talking to Pops, Anderson says 'Colonel'. Pop's rank is a 2nd Lt, and Razgriz/Wardog Squadron is only Captains. in fact, the only Colonel in the game is Perrault, the Base Commander on Sand Island.
Bug: When you get the fireball effect (when exiting the orbit or at very high speeds) if you try to turn too much with the Delta-Glider that comes with the game, after a while the ailerons (which are also the elevators) come off yet you can still pull up or pull down without any movement of the elevator (which are the ailerons and are removed) but you cannot turn at all.
Continuity mistake: When going into any level where you play as Coco, we see Crash going into the teleporter, but why would Coco be there when the level begins, as we never saw her stepping into the teleporter.
