Personal Mandela effect?

I recall there being a Catscratch video game on the Gameboy Advance. I mean, the only other underated Nicktoons of the 2000's, El Tigre and Back at the Barnyard, have video games either way, and Mr. Blik did appear as a playable character in the DS version of Nicktoons: Attack of the Toybots, but there is no Catscratch video game. But I remembered it, as a YouTube video (that is coincidently lost) of a GBA collection with Mario plushes, akin to SML's Wii game collection video, included the Catscratch GBA game. I even remember the label having a purple background with the Catscratch logo, The Nick Games logo. the THQ logo, if I'm not mistaking, I think I saw a Alcon logo, ESRB rated E logo, and the Nintendo Seal of Quality, plus some copyright stuff. The kid with the Mario plush said the game was bad or something and at the end of the video, Yoshi ate the bad games.

The video was probably the only time I knew of a GBA game based on Catscratch, and I'm surprised that years later, when THQ Nordic announced they're making Nickelodeon games with the licenses to the properties the original THQ used, with Catscratch being one of the properties, I all of a sudden remembered there being a Catscratch GBA game back during the peak of Nickelodeon video games, and when I tried looking for it on Google, all I got are images of the web games rather than a GBA game based on Catscratch. I even tried to find the specific GBA collection video with the Mario plushes since that's the only source of the lost Catscratch video game, but alas, the video was deleted I guess. But I swore Catscratch had a Gameboy Advance game that came out during the peak of Nickelodeon video game.

Similarly, I used to believe that the original Toy Story came out in 1986 for some reason, even though it came out in 1995.

Thing is, I had no idea that The Works even existed back when I believed that(this was like, 2010). I assume that the belief might've been inherited from my dad.

Or maybe his brother? I have no idea where the misconception originated from my perspective.

Jeez, I seem to have had quite the mandela effect on Ristar of all things. I used this longplay for reference & it's divided into rounds just like the game itself & are ordered by when they appear so you can follow along with the longplay when reading these:

Before the longplay begins:
1. IDK why, but when I first played this game, I thought this was a German game. How I came to that conclusion back then is a mystery & this was before I learned that German video games were mostly a C64/Amiga thing instead. For what it's worth, I DO have German roots on my mom's side.
2. I remember the Sega logo part being lower pitched than usual when I played it on Sonic's Ultimate Genesis Collection on PS3. This is not the case & it's only like that on AtGames machines.
3. I kinda also recall there being more to the 2nd opening theme, with the last note being on a different note.

Planet Flora:
4. Those redball flowers I could've sworn were more animated than they actually are, as in they had a glowing effect. In actuality, they don't glow.
5. The spiky bushes had a slightly bigger hitbox in my memories than what it actually is.
6. The 3rd background layer on planet Flora moves slower than I remember it. It was still parallax scrolling, but the 2nd & 3rd layers were moving at almost the same speed as each other, with presumably the 3rd layer only a few centimeters slower than the 2nd layer.
7. The bushy trees at the 1st polering I remember being angry faces & they didn't have that weird wheel-like nose in the middle. The bushes on top of the eyes I thought represented eyebrows; I remember the eyebrows being more jagged as well.
8. The top ball on the bonus level polering I remember being blue instead of gray.
9. This one might actually be true? I remember being able to throw the bonus level treasure once you got it in your hands & were quick enough. Can anyone verify this?
10. For some weird reason, I remember getting 21000 points at the height bonus in 1-1 because I went higher than I thought I would.
11. In 1-2, there is a statue in the background. Kid me thought it was some beaten up robot similar to the ones you see in Armored Core.
12. As a kid, the purpleness of the background meant that there was a fog covering up what was over there, not that it would matter since it's so far away.
13. I also remembered that you had to grab the tree thrice to chop it down, but in reality you only need to do it twice.
14. The place where the bonus polering was in 1-2 had more towers in my weird memories. The actual game has 5 of them, but I could remember it having 12 of them.
Not a Mandela effect: You can skip the 4th pole to the left & instead swing back to the 3rd pole on a higher level & immediately grab the 5th pole to the right.
15. In the big hut below the polering's place, there were more of those little blue crawlers in my memories than what's actually in there.
16. The strawberries the guy in the background throws I thought were something else that looked similar to a human heart & was like a bomb.
17. I remembered the 1st boss's name being Krio, but instead it's Riho.
18. Apparently I didn't notice the 3rd purple flower in the boss fight, thinking there was only one on each side.
19. Might be a weird regional/revisional thing. Whenever I defeated a boss, Ristar says "MA!". In the US version, Ristar just does a thumbs up in some bosses instead of always saying "MA!" after a boss is defeated? Weird.

Planet Undertow:
20. I remember the sand in the background being of a lighter green(specifically X11 green)
21. Those buildings I remember having weird lights in them instead of just having some red... thing inside of them.
22. I remember the music in 2-1 being 2-3 minutes longer than it actually is. Might have something to do with me spending a lot of time on that level.
23. The 2-1 miniboss crawlers throw things at you, but for some weird reason I thought those were shoes instead of rocks.
24. The pufferfish in the miniboss I remember being more panicked(as in twitching faster) when they got on the ground than they actually are.
25. 2-2 music I swore had a few more notes in the beginning bass segment than I thought.
26. The humming seems to be less faded than I remember it being.
27. I remember there being another bar before the PSG panic section of the music.
28. The underwater background I remember being darker, like noticeably darker in comparison. The closest blue I can think of that matches is International Klein Blue, but even that still is somewhat lighter compared to my estranged memories.
29. The wavy effect is much more noticeable than I remembered.
30. Bizarrely, I remember that you didn't have to hit the fans & I only hit them every time for fun. Nope, it's a required hitting.
31. I remember the bubbles leading up to 2-2's polering disappearing slightly faster.
32. In an inverse of 30, I remember having to defeat the last stoneface so that the end of level polering would show up. Nope, you don't have to, you can just get to the polering.

Planet Scorch:
33. I remember it being named Scorcha instead.
34. Those PSG notes I don't remember being in 3-1's music.
35. I remember the background being more vibrant, having some pyramids(or volcanoes?) deep within the background & a red sky.
36. The platforms at 19:24 I remember having a somewhat darker color, like about 4 shades darker?
37. The fireballs at 20:19 I remember being a bit of a dark red shade. I think it was specifically a maximum red?
38. The trap button near the sideways pole I remember making a sound when you press it, but oddly it doesn't make a sound?
39. I remember the 3-1 miniboss being a fair bit less forgiving.
For the rest of the stages, I got to them through the level select code.
40. I remember the 3-2's music sounding a bit different instrumentally: The dings were a bit more of a PSG/FM hybrid & the bass was somewhat louder.
41. The last few notes of the 3-2 music I remember flowing more naturally than how it actually is.
42. I remember the mole boss(Adahan?) not jumping until about 3 seconds into the main boss theme kicks in.

Planet Sonata:
43. I remember that the final song once you gave all 4 birds their meters combined both the intermission AND the ba's! Alas, it just plays the samples & not the intermission segment anymore.
44. For some reason, I always thought there was a futuristic car that would appear on the right side of the road on very rare occasions. Never happens in actuality.
45. The inside section of 4-1's background I remember being a bit more magenta as opposed to violet. It was still dotted though even on an analog TV.
46. I remember the 4-2 background being MUCH more vibrant & colorful, having some sort of crazy outdoor concert in the woods vibe in my strange memories.
47. I remember the song being a bit longer as well.
48. I don't remember the guitars being as quick to drop down in 4-2 as shown in the longplay.
49. The piano notes you grab made a different sound that was more similar to the stereotypical piano sound(something like this). Probably has something to do with me remembering having played some piano game on an iPad before whose name I can't remember.
50. The trumpet's faces I remember could do a tiny bounce in comparison to the big bounces the bongo drums do.
51. I could've sworn that the dark green crawlers would fall down when you hit the 3-hole thingies that are hanging on the ceiling & you would have to be very careful on where you land.
That's as far as I got. I used the level select to get here like I've said before.

Planet Freon:
52. I remember it being Frion instead.
53. I remember icing on the ice cream cones in the background having the 2 circles in the center, resembling eyes.
54. The gradient colors were different in my memories: instead of going from orange to magenta to purple, it went from cyan to medium blue to purple.
55. I remember the foreground generally being more purple & magenta than blue & cyan.
56. I don't remember any explosion noises when Ristar hit the snow in his zooming phase.
57. I remember him just going down the slope in his zooming form, THEN showing up again in skis. In actuality, he falls through the foreground.
58. Ditto for when he's skiing.
59. Alongside those little gem trees, there were gem bases of sorts that were shaped like wrenches whose heads were bent forwards(both colored purple of course)
60. Another absent background object I remember is a small pyramid for some unexplained reason. Maybe I remember 5-10 of them being in 5-1.
61. First level design difference! I didn't remember the treasure box at 41:30.
62. The spiky background objects were FAR more commonplace
63. The 5-1 miniboss I don't remember moving to the left side of the screen as much as shown in the longplay. You had to get a fair bit closer to him in order for the snowballs to land, which was somewhat of a risky move in certain circumstances.
64. I remember those trees being more colorful, having a "morning blue" sort of color on the body & the 2 small leaves being a darker orange, plus the top part being a seashell than a shake swirl.
65. The spike spitter looked similar to that weird plum-like plant in the layer 1 background, complete with the leaves & holes.
66. The underwater gray crawlers were more like the Star Light Zone's version of the Orbinaut, in which there were spikeballs all around him, making it harder to get to the crawler himself.
67. I remember the fish being red like they were on Undertow instead of yellow.
68. I remember the dashes only going in one direction. Right on platform 1, left on the other platforms. The path of the all-seeing creature was the only time I thought I saw them go both ways on a single platform.
69. I remember Itamor bouncing a lot higher.

Planet Automation:
70. Like with 5-2, I remember the background being more vibrant & colorful. The white void was more angular & simpler while the ooze was black instead of dark green. Those weird square towers were salt shakers, there were more Jetsons-esque houses, there were weird hexagonal stars of sorts, it was just so much stranger in my head.
71. The sliding scale robots I remember being a bit slower.
72. The robots who shoot 3 lazers I thought would only shoot when they detect you & would otherwise just buzz off out through the left side of the screen.
73. The spiked poles were violet as opposed to red.
74. I remember those bluelight/redlight helicopter robots having wings instead of just being a cylinder with a propeller... even though helicopters don't have such things, but ok.
I used level select to get to 6-2
75. I remember having to ram that erratically flying robot into that out-of-place wall in order to break it. There IS a later segment where you do just that with a 2-legged blue robot though.
76. For some reason, I misremembered the "going into a different layer of the factory" section as a gravity being flipped section where the controls are reversed.
More level select shenanigans to get to round 6's boss:
77. I remember that giant claw being much faster & more likely to follow you around than in actuality.

Final boss:
78. I never beaten the final boss, but I DO remember the 2 tubes on each side having their insides move downwards like DNAs.

And those are the mandela effects I have on Ristar. Man, there were A LOT more of these than I thought I had for this game. Guess it goes to show how little I've played of it since... mid-late 2021 I think? Man, I gotta replay this someday. Thanks for reading this if you have.

i used to think for the longest time the cover of pokemon red and blue were two vague dragon things. i ALSO remember in a mandjtv video on scrapped pokemon talking about said vague dragon pokemon, and how they were meant to be gen 1's "box legendaries" and that's why they're on the cover. it's so weird :/

On a similar note I also thought for a while that Gumby was from Aardman.

I also thought Alec Baldwin played Obi Wan so yeah.
