Back in the red/blue days, 10-year-old me was briefly obsessed with Missing Number. I noticed, after catching one just to see what would happen, that beating the Elite 4 afterward caused my winning pokemon images to glitch...one of them glitched into a sprite of Mew. After I realized Missing Number can evolve, I experimented for a pretty long time; convinced that there was some sort of massive secret locked within this glitched mess of pixels. As with almost all the "secrets" (more like child folk-lore) from those games, there really was nothing to find.

"Child folk-lore" is so fascinating to me. There's an academic term for this, "children's culture" -- the unique subculture created and maintained by children, with little to no influence from adults. Somehow through friendships with kids at other schools, cousins in other states and countries, etc. you end up with this global "children's culture" that propagates itself. Even as we grow out of childhood, new young children replace us and maintain many of the traditions and beliefs we left behind. I remember a Reddit comment where somebody shared some of the new Pokemon rumors he learned from his young child. The most fascinating thing was that corrupted versions of the same rumors from 20+ years ago still persisted among these young kids. Apparently this guy's kid heard about a secret Pokemon named "Mysterio" who could give you many items but at the risk of destroying your game. The legend of Missingno lives on, retained through oral tradition amongst children. That's pretty mind-blowing to me.

As a programmer who grew up with Pokemon Blue, this is particularly fascinating (though I want to know more about the decompression algorithm and should probably just go read it on the "pokered" project on Github). The workings of these older, simpler machines and the clever tricks they used to work around limited memory space and CPU speed are amazing to see. But this stuff is pretty much meaningless if you want to make modern games or software -- you shouldn't be doing anything like this, and if you do and it glitches out like this you just see "Segmentation fault" or a pretty backtrace pointing out the exact line in your code where the poo hit the fan.

I would've expected them to implement a small arbitrary line length and filesize limit, along with rejecting any files with non-printable characters in them sometime in the 00s. I know Notepad has a filesize limit, but it'll stop responding and get extremely sluggish long before you hit it, and I know many text editors in Linux have a line length limit, but they'll all open files with invalid bytes in them. I know multiple codepages are a thing, but even then, it's a rare find in modern computing. I get Audacity's raw audio option, since it's impossible for them to tell apart what's intended to be digital audio and what isn't. The raw audio format itself uses the entire byte range and has no parameters or headers aside from the waveform's samples themselves, making literally anything 100% valid raw digital audio. But afaik, the different plaintext formats don't use the entire byte range and positions for printable text characters, so invalid bytes should be possible to catch, and in fact are caught...

When you encounter a pokemon, the game looks for a bit representing the "seen" box in the pokedex. If it's 0, it flips it to a 1. This only works properly for pokedex numbers 1-151. Since missingno. has a pokedex number of 0, the pokedex is looking outside of the data it should. The bit it's actually checking is the largest bit of the byte that represents the quantity of the 6th item in your bag. So if you have less than 128 of the 6th item, the game finds a 0 bit at the point where missingno.'s "seen" data is supposed to be, and flips it to a 1. This adds 128 of the 6th item to your bag.

@smb85 dkc94 from my understanding, there are basically 256 spots for pokemon, and because your name is being written to the encounter slots for pokemon, it will look for whatever your name's letters point to in memory in terms of pokemon, and it will very likely stumble across an "empty slot", at which point you get a missingno or similar. So now everyone is please free to correct me, but with the exact same coding, if there'd been 256 legit pokemon, there'd have been no possibility of missingno's appearing because the letters of your name would always point to a real pokemon.

@@foamingstuffye3951 Fun fact - there are exactly 256 pokemon in gen II, and it uses the exact same system. Not only does it not have any glitch pokemon, but every gen I glitch pokemon will turn into a real pokemon if traded to a gen II game using the time capsule. If anything like the Old Man Glitch were to exist in gen II, it would not make any glitch pokemon.

Fixing garbage data ... hmm is it even possible?

@olbluelips 3 жыл бұрын

Well, the data isn't an image in the first place, so it would look like garbage no matter what. Maybe you could set reasonable top-left offsets, but it wouldn't look normal

Wow, you are unbelievable, such a good explanation of this, I didn't expect to find this level is depth

You do a really good job of explaining complicated things at a good pace in simplistic ways, and the graphics really help. A lot of similar channels don't give you the pause to appreciate what was just said before continuing.

I'm impressed by your level of knowledge on this, it answers a lot of questions! So excited to go watch the follow-up video now, I was wondering if you could "fix" those sprites what they'd look like :D

Man you put so much work into these videos its beyond impressive. When I caught Missingno on my Blue cart it completely ruined the cartridge's ability to keep a save game. Even after swapping the battery in the cartridge, which I thought would remove any altered data, it STILL wont keep a save.

SRAM doesn't lose its data immediately when it loses power, it may keep bits and pieces for a while, you can help it out by shorting out the pins (e.g. with a screwdriver) in the battery socket. If you are sure the SRAM is completely cleared, and it's still not working, then I congratulate you on breaking the laws of physics.
