It's really amazing that they're able to not just take over the game program, but actually patch their own subroutine in and then resume the game as normal while retaining control.
If that console could exist, how could be possible to input something into it? NES does not have proper keyboard accessory, which would allow that to happen.
if im not mistaken then SMB3 is canonically a show like you may whitness in a theatre so this whole TAS was mario changing the script and having fun doing so.
I'd love to have been the kid in like 1990 who somehow did juuuuuust the right insane button presses somehow fast enough at the right place to make this kinda thing happen. Next-level cheat codes; just make the game behave however you want with jazz hands and an imagination!
Normally this would be very hard to do with an NES game because the NES has 2kB of RAM, and most games make use of all of it or close to all of it. SMB3 however has an extra 8kB of RAM inside the cartridge which is used to store the level maps because they have breakable blocks, so the maps can't stay in ROM, which is static.
The ROM chips in the cartridge have the data encoded as physical wires, so its impossible to write to them without actually changing the chips themselves. You can stream data into RAM though, in this case from the controller which is what this TAS does. Every disk based console does this too, though from an optical disk instead of from the controller port.
ROM files are 40K, so technically the NES has 40k, the VIC-20 has 5K, 2K used by the system, and that doesn't support sprites and is very limited unlike the NES.
This TAS is just literally ridiculous in so many ways. The "color-a-dinosaur" is literally a work of art for NES programming. Also, changing the pattern banks is so LOL. I didn't even know NES Mario 3 even had Speed Booster mechanics from Super Metroid for executing this arbitrary code. It may have also predated said game as well. There's also this "ShellShield" which may just be an early mockup of the actual Shell Shield from Paper Mario: The Thousand-Year Door for that matter, but these debug features can also allow you to shift between forms. Those messed up auto-scrolls really do put things out of place. And of course, you can also disable them too! Last but not least, Bowser taking over 30 fireball hits? He would be toast instead with one Koopa shell! This apparently did predate a very similar feature included in the limited-time battle royale game Super Mario Bros. 35, or did it? And also, I noticed that the life counter jumped straight to 99 at the end of the TAS.
I watched this several times, and I never noticed that the "Color a Dinosaur" part was actually running a paint-like program (I thought it was like a hard-coded cutscene, or something).
This is legit? WTF? How must that have gone down? "I'm bored.... Let's play Super Mario Bros. 3 and heavily reprogram it from INSIDE THE GAME! With a console and everything. Let's add elements from Super Metroid and stuff! YEAH!!"
+Lord Tom In the Author's comments in the video you state that the shinespark works in 5 directions. Why didn't you go the full 8 directions? To save coding time?
+TheSuckerOfTheWorld I thought that was how the Super Metroid one worked; can you do one downward in SM? All 8 wouldn't have been more work particularly.
Honestly I wish games still had this type of stuff in them. Too bad the internet would ruin it now. I never knew about this untill today. And thats how it should be. But now everything is found like in a week or few days of release
Well the Shigeru Miyamoto stuff was a joke; that screen was entirely programmed by the TAS creator. There's no "real" debug screen, just whatever the TAS creator can program into the game using the game's inputs.
@@randomguyontheinternet7940 I mean, sort of? It wasn't in the original game, but the way the TAS works, it basically recreated Color a Dinosaur within the game.
When I first watched this, I couldn't believe it was actually being emulated. I thought someone had just animated it! Clearly, I didn't see the rapid button inputs in the bottom left as I didn't realise the 6502 code execution pointer had jumped to the memory address of the controllers. This was clearly before I had discovered 'Retro Game Mechanics Explained', and before subtitles were added to this video. Also, I never knew the NES ran on Unix. (joking) (7:53) Hmm yes Mario just casually sliding through a wall.
They take advantage of very precise frame and pixel perfect automated gameplay that allows them to write the console's random access memory exactly the way they want to through gameplay. Then, their final glitch before the console goes completely nuts allows them to run what they've written by playing the game as if it were actual processor (computer) binary language. This bit of code starts listening for controller inputs and treating them as new applications to run. Those random controller presses you see displayed in the lower left corner are not random. They are telling the console what to run next. They still have the cartridge on, so they can also call real game functions and elements through their glitch as well. It's insane.
This is possible because RAM memory is just a reeeeaaalllly large string full of data, and old games have no error-handling. This can be exploited to force the console to read pieces of data in the wrong format. Imagine... A computer trying to play a picture as if it were audio (I'm sure you can't, it's not really easy lol). In this case, it reads sprite/gameplay data as if it were code. But unlike the previous picture example, where it'd just actually play a lot of cybernetic computery noise and blow your eardrums, the gameplay data here has been cleverly manipulated to be actually fucking meaningful. This makes it mesmerizing to see in action.
@@3lH4ck3rC0mf0r7 yeah its insane to think for someone like me who dosnt know coding but I kind of get it because with the cartridge its not like the levels are already made on the cartridge right, its just the string of data and then when played it gets told what to show n how to play.

ASM for old processors is fun! But for modern ones it can be your death sentence... start out with something simple... just make something that can play different sounds based on button presses or something like that. Maybe put something on the screen!
I understand that the effects of the glitch are caused by the X position of the enemies in 7-1, and the code is activated by touching the glitched music note, but what I never saw explained is, what causes the wrong warp itself? It's the act of going down the pipe from that glitched position at 2:44 what causes it?
By playing the game normally you're already doing arbitraty code execution with controller inputs but at a user level that it won't harm a normal game play. That and the fact levels do not let you stay long enough to see things going apeshit once things reaches 999999999 or 255, which, takes almost a life time through normal means (see the 256 error in PacMan, or how Yoshi and Mario NEEDS to cross a certain gate to keep the game's balance due to dev's overlook as an example). Only glitches let you get things go apeshit faster. In this case, the wrong warp can result in infinite endings if some part of the code has been touched up already (moving to X location, knocking X enemies in X positions, etc). And since the devs didn't overlook the warps at the pipes, you can glitch through them almost anywhere. Carrying whatever code mentioned above with them with epic proportion results. That means if you can somehow manage to get 28000 lines of code in the brief moment the wrong warp happens, you are literally writting a new game in ram using existing data off the cart. Edit. Didn't check the comment was 4 years old. YOu might know about all this by now. :P
