Bug: A rather infamous shortcut glitch is in Wario Stadium, where the very first hill after the starting line is high enough that if you hit it at an angle you can completely jump over the wall. This cuts off a significant portion of the track, putting the player way ahead. Then on top of that, if you turn around and hit a part of the wall just right at a good angle, it will cause you to jump back over the wall before the finish line, cutting off the full track. Do it right, and you can complete the full three laps in under 30 seconds.
Bug: Woodman Stage: After defeating the second Friender enemy (the large fire breathing blue cats), if you hang to the right of the screen when jumping down to the next area and are still hanging in the air when the screen scrolls over, MegaMan will phase right through he wall instead of going under it, just before reaching the third Friender.
Factual error: In the original English NES copies of this game, at the end of the game it says the Robot Masters are made by Dr. Right instead of Dr. Light. Dr. Right is his name in the Japanese version.
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.
Character mistake: After the Duo stage, ProtoMan says "What happend?" Happend should be happened.
Other mistake: When you finish the classic mode, there's a credit. When you see Charles Martinet's name, it says "Martinee" instead of "Martinet."
Other mistake: Intro Mission 1: Once the characters get their powers, pressing Z uses up their "Cosmic." Cosmic is the blue bar underneath the green health bar. On Mission 1 of the Intro level, it is before the cosmic cloud hits the station, thus none of them have any powers or cosmic yet. However, you are controlling Ben in a space suit out on the space station, and he has a blue bar of cosmic below his health. If you hold down Z, you see the Cosmic begin dropping from 100 and the blue bar move.
Bug: So far, I have only found this glitch in Dust Bowl on the second capture point in stage 2. On the Red Team side, exiting the starting room, you see a folding down garage door that is always shut. Sometimes, it will be off set. The door is not connected right, and actually sticks out into to the walk way. Players can walk through it, and can't go in the door though due to an invisible wall.
Continuity mistake: Prologue: The lipstick Padme drops in the opening clip vanishes as the level starts.
Bug: Space Construct: About two thirds of the way through the map, you come to an S shaped thin blue path that has gravity lifters turned sideways along the edges at some points. The lifters there to push you off the path if you don't hit the spot just right. Sometimes when jumping over the lifters and a high speed and landing on the path, the Spectraball will suddenly become lodged into the path, stuck through it. You can not get out and have to restart from last checkpoint.
Continuity mistake: Episode 1: Night of the Mutants - In the sewer, Sketch has to defeat Stigril. After doing that he then climbs down the comic strip and lands in another part of the sewer, where there are two barrels set on fire. Destroy these and leap to the next part of the comic. Visible to the left hand side of the image, is a skeleton. As Sketch leaps over the next part of the comic, the skeleton vanishes from shot.
Continuity mistake: Principal Skinner is shown in Bart's Nightmare with very tan skin and brown hair, instead of the yellow skin and grey hair he is usually seen with in the show.
Revealing mistake: The Apocalypse/Mayhem: During the cut scene before your first battle with Straga, various Angels and Demons are fighting. It shows one Minion Demon holding an Angel Soldier, and in the over head shot he's holding the Angel's torso up off the ground. When it cuts to a side angle just before the Demon rips out the Angel's throat, suddenly the Angel is not only on the ground, but almost completely inside the ground with just part of his face and torso sticking out in a bad animation moment.
Revealing mistake: Lockdown: In the Med Lab section of the space station, there are plants growing along the walls and the floor in one hallway. If you go past and into the next room, some of the leaves of a bush are sticking through the wall in a clipping error.
Other mistake: In a lot of older games, a 2D sprite would just be flipped showing a character turning around, so older games it would be normal to have an item in a character's left hand but turn around and it be in the right. However this game is a 2.5 D game with 3D characters and most of them don't have this issue. Like Auto having a hook like extension as his right hand with it staying consistent to his right if he turns around. However when Rock (MegaMan) rushes in after Dr. Wily breaks in, he has a vacuum like broom device in his right hand. When Dr. Wily lifts off out of there, Rock turns around and suddenly the broom jumps to his left hand, staying towards the screen. You even see it stay in his right hand as he's turning but then suddenly jumps to his other hand.
