Continuity mistake: Bargain Bin: When the 8-bit Simpsons are headed for the furnace, they are almost half way down the line to the furnace. When the level starts, the 8-bit Simpsons are suddenly next to the platform Homer and Bart stand on, hardly anywhere near where they were a moment ago.
Continuity mistake: Bargain Bin: The wall behind the 8-bit Simpsons in the "Escape from Krusty Island" game is grey, but as the level starts, the wall behind them is black.
Continuity mistake: Bargain Bin: After completing the level, the Simpsons arriving in the theatre. No-one is shown in the ticket box, but when it goes back to the game, Professor Frink has suddenly appeared in the ticket box.
Continuity mistake: Bargain Bin: In the final part of this level where you have to save the 8-bit Simpsons from being thrown into the furnace, if there are only a few seconds left on the clock, the 8-bit Simpsons will appear next to the furnace. If you then pull a lever, a huge curtain will close the furnace. As the curtain is placed, the 8-bit Simpsons will have vanished from in front of the furnace, even if the lever is pulled only a few seconds before the clock finishes counting down.
Other mistake: Bargain Bin: Whenever Homer and Bart fall off the platform, they would usually die from the fall. As they hit the ground, they go through some random object on the floor. If there is no object on the floor, then they just land on the ground, but still continue to act as if they are falling.
Plot hole: Bargain Bin: After Homer and Bart save the 8-bit Simpsons from being burned in the furnace, Homer and Bart run into an elevator while the 8-bit Simpsons remain inside the "Escape from Krusty Island" game. When the elevator opens, the Simpsons walk into a theatre and discover the 8-bit Simpsons are there waiting for them. How did they get there so quickly? There certainly would be no time for them to escape the game and get to the theatre before the Simpsons did as the Simpsons had a huge head start on them.
Audio problem: Bargain Bin: When Homer asks "You like doughnuts too?" to 8-bit Homer, the poorly rendered Homer mouths the word "too" as well, but nothing is heard.
Continuity mistake: Bargain Bin: In the wide overview shot of Homer and Bart exiting the elevator into the theatre, the 8-bit Simpsons aren't there. A few shots later, the 8-bit Simpsons suddenly appear.
Audio problem: Bargain Bin: Just after Homer and Bart save the 8-bit Simpsons, Homer and Bart run into the elevator. Will Wright then says "Who put you up to this? Was it those jerks at EA? They're jealous of me, you know?" His mouth reads something totally different when he says this.
Continuity mistake: Bargain Bin: Throughout the opening cutscene inside the Game Engine, all five Simpsons are shown together, but in the shot where Bart says "And poorly rendered" and Marge says "Which one is supposed to be me?", Lisa has vanished and reappears in the next shot.
Continuity mistake: Bargain Bin: When the Simpsons arrive in the Game Engine, they keep switching from all even with each other to Bart and Lisa standing in front of Homer and Marge.
Continuity mistake: Bargain Bin: As soon as the level starts, Marge, Lisa and Maggie vanish from next to Homer and Bart.
Continuity mistake: Bargain Bin: At the start of the intro cutscene, the alien Mothership hovers over the Simpsons' front yard. In the next shot, when the Simpsons run outside, the Mothership hovers over the yard a second time.
Other mistake: Shadow of the Colossal Donut: Homer and Bart's main and only objective in this level is to open each of the three hatches inside Lard Lad and rip out the circuits inside him. To open the hatch, Bart will need to launch a slingshot at Lard Lad's hatches. After the hatch is opened, and the circuits have been ripped out, the hatch will always vanish completely.
Revealing mistake: Invasion of the Yokel Snatchers: When Homer and Bart watch the mall be invaded, the citizens being sucked into the ship are just the same people repeated three times.
Bug: Day of the Dolphin: In the underground aquarium scene where you have to defeat Snorky, switch to Lisa and use her Hand Of Buddha power to move the jellyfish and place them on the hexagon-shaped grey platforms on the left corner on the screen. If you place one of the jellyfish on the platform and drop the other one, the jellyfish you dropped cannot be picked up a second time. It will just be stuck on the ground.
Continuity mistake: Day of the Dolphin: During the intro cutscene, Captain McAllister is untied from the ropes. Part of the rope he holds in his hand, then eventually he drops the rope. As soon as the level starts, the rope he dropped is no longer visible.
Continuity mistake: Enter The Cheatrix: During the final boss battle between Bart, Lisa and the Ape, you have to strike the ape with Lisa's hand lightning and battle Kung fu fighters entering through elevators. If you completely ignore these fighters and just go straight to taking the ape down, the ape will die after 3 lightning strikes and fall into the game waste stuff. The conclusion clip starts to play where Professor Frink gives the manual to Bart and Lisa, and yet the Kung Fu fighters don't seem to be there anymore, even if you didn't bother to take them down.
Plot hole: Enter The Cheatrix: The level shows Bart and Lisa chase the ape holding Professor Frink. Each part of the level consists of Bart and Lisa running through each place the ape went through. If that is so, while it has been shown to jump a few meters, it doesn't make sense how the ape was able to jump over two huge buckets of blood that was almost five times as more as a jump than it can usually handle. Even if the ape swam through the blood, there should still be blood on it or Professor Frink's clothes.
Deliberate mistake: Enter The Cheatrix: Any time in this level that shows one player jump into a pipe, the next scene shows two players exiting the pipe at the same time.
