[@OctagonalSquare]

Fun little thing that is kinda mentioned. As you said at the end, your color palette is determined by the power up status. I know some people are like “how come there is a small fire Mario sprite?” Well that’s because it’s just a palette swap. All they do is switch which color goes where, and the sprite just says which color in the palette, not specific colors. So technically all sprites have a massive number of variants

[@MegaZeta]

If you want to get into "technically", sprites on this system _don't_ have a massive number of variants in that way. Palettes are heavily restricted by everything else on screen at the same time. It's one reason why Mario is the colors he is.

[@OctagonalSquare]

@@MegaZeta well I just mean that you could theoretically use any of your palettes on a sprite. Yeah, there’s a limit to how many unique colors can be on screen and such, but the fact is, there is a way you can display tons of different variants for each sprite

It would be really cool if you could get Small Fire in newer games when collecting a Fire Flower while being Small Mario Also, I think the counter-intuitive Super/Small values, with Super Mario being 0, and Small Mario being 1, is because Mario was always going to be 2 tiles tall, but they implemented the shrinking later

[@saltygibus5746]

That would be pretty fun! Maybe it'd be part of it's own power-ups based on heat mirages. Mirage Mario, if you will. He could fire fireballs like normal Fire Mario, but these ones merely stun enemies instead of KOing them, along with giving Mario the ability to break bricks and do Super Mario things with the Small Mario hitbox.It'd also transition you to Small Mario immediately on hit--basically, an Expert Mode version of the Fire Flower.

@@ToaderTheToad True. But it also fits how not one Power-Up is objectively superior to another.

[@koopakape]

Makes a lot of sense, considering in the last Mario game before this, Wrecking Crew, he was always 2 tiles, and ever since SM64 it's been very established that his "super" state is his default and in most games he never shrinks.

[@ToaderTheToad]

@@koopakape Yeah I always found it weird, especially since Donkey Kong actually has a similar sprite to SMB's Small Mario (Yet he's not depicted as being small in most non-sprite interpretations)

[@leroyvisiongames2294]

The reason the value for small Mario is “1” is because his placeholder graphic was a 16x32 rectangle, meaning his large size was originally the default. The size-changing mechanic was still conceived early in development, but they didn’t come up with that idea until they were already in the midst of sketching out his sprites on graph paper (in old development footage, you can see early designs for Mario’s death animation using the “big Mario” sprites, as well as some unused poses of him scratching his chin. The death animation also originally had two frames for him flailing his arms like in Mario Bros. arcade. The “small Mario” sprites probably took up the memory that was originally reserved for these extra animations)

I think it's pretty cool that Small Fire Mario was directly mentioned in the NES Remix games for a couple of challenges where you have to beat levels as Small Fire Mario.

I know there’s a “Death Mario” that’s basically a grey Mario that can’t be killed, but he can’t go down pipes. Apparently, this is because he’s actually the Tanooki Statue in that state.

@@fastbreak333 Yep. If you tanooki while getting a powerup, you become that powerup but grey. another side effect is you can stomp anything tanooki can, but you almost never see this without a cheating device because the places where you can get it 'naturally' have no enemies (to my recollection).

What I especially love about this glitch is that it's technically canon to the Mario Movie universe See, in the movie, Super Mushroom's powers are actually unique benefits, instead of just being a gateway to a better one. In the movie, we see Mario with a Cat Suit and a Tanooki Suit, but he isn't Super Mario size for either of these, and it's safe to assume the Fire Flower works the same way, even if we don't see him use it in the movie

[@NiGHTSnoob]

I had this happen once when I was a little kid like 25 years ago and I thought I just misremembered. Thank you for solving this mystery for me.

[@saeklin]

Having an epiphany right now because I just realized Small Mario is really just Regular Mario. Big Mario is the powered-up state making him a giant that can go head-to-head with Bowser, quite literally. And also, its clear that the Fire Flower originally didn't also make Mario big. He'd need to find both the mushroom and the fire flower to achieve Big Fire Mario. All this time I thought that small Mario was like a weakened state and that big Mario was the default. This changes everything about how I perceive the scale of the monsters in the first 3 games.

[@otakubullfrog1665]

When it comes to boolean flags in programs, while zero is false and one is true, the reason that the values often seem counterintuitive when reverse engineering a program is because you don't know how the programmer was thinking about state. If the programmer was thinking about it as a flag for whether Mario was small instead of whether Mario was big, the true and false values make perfect sense. Since setting a flag usually indicates that something has changed, perhaps big Mario being considered the normal state suggests that he was at one point going to start the game that way (sort of like how you start with the armor in Ghosts 'n Goblins).

[@Roxrock]

There is also glitched powerups in smb3 that you can access with ACE. It might be possible to change your powerup state as well, you can with game geni codes. In smb2U, I found a code that lets you choose your charecter twice, creating weird conglomerates of the two you selected, although their more glitched charecters than powerups.

[@ZaCloud-Animations___she-her]

Ooh, I'd love to see that! 😲

[@SomeGuy712x]

I remember discovering this on my own way back then. For whatever reason, I tried to jump on Bowser and the axe at the same time, got the shrinking sound, and expected to start the next level small. However, I stayed big, and to my surprise (and the surprise of others watching me), the next power up was a mushroom that shrunk me, and I soon got small fire status afterwards. Also, when I got hit and grew, someone else watching me said something like, "Oh, if you get hit again, you'll just shrink.", but I figured that the next hit I took while big would actually kill me, which was correct. (I think I ended up losing that particular life by falling into a pit, so we didn't actually see at the time that getting hit while big was fatal.) Oh, and doing this glitch while small and dying is amusing, especially since the game will usually play the death music again after the victory music finishes.

i could kinda see a hack being made around these counterintuitive variables. the usual mushroom and fireflower would still change marios state, but changing his size would be done by some other means such as collecting a separate pickup or jumping on a p-switch-like tile. would probably make for some interesting puzzles should the hacker also patch out wallclipping maybe

[@chappieenzijnvriendjes6336]

This is interesting because even modern Mario games use this mechanic. That's why you can interchange suits and powerups - they're handled independently.

[@nakano15]

I believe the mario collisio height might also be related to the size value. If, let's say, the collision height calculation is 64 - 32 * MarioSize, then setting size to 2 invalidates any kind of collision above Mario. I wonder what happens if a value over 2 is set.

Still unknown to me is how Fire Mario colors are on the small sprite and how the game knows to put it in that state on small Mario after getting a fire flower.

[@Suspinded]

This is explained starting at 4:30. Color palate is tied to the power up state. Palate is separate from the shape. It just defines the paint colors in the paint by number way sprite drawing is handled.

[@cornbreadbutcringey5723]

color information is separate from the sprite itself on the nes, so 'small fire sprites' don't really need to exist. actually, big fire sprites don't exist either. nor luigi sprites.

If you want new Mario powerups that no one has seen before, when I was a kid I noticed that all of the Game Genie powerup codes for Super Mario Bros 3 were the same except for a few characters, so I put different characters in those spots to see what happened, and in some cases it did actually result in some funny glitch powerups.
