The reason why you're able to go past the edge of the map and into the void and go so far to the right that it warps and eventually crashes the game is because when you defeat the boss, the boss' object code begins to slowly shift the far right boundary or increment the value of the far right boundary (in other words) until it gets to a certain point and then stops and at that point the boss object basically deletes it's self. However due to the way they programmed it, it doesn't check if the far right boundary is already set to it's intended value or higher than the intended value and therefore it keeps going and doesn't stop. If the game didn't crash it would have eventually looped around to 0 and continued until it got to where it should be. In a rom hack this can be easily avoided by directly setting the far right boundary value instead of slowly incrementing it and checking if it's in the correct position.
This act is left over in the final version of sonic 1 by putting the act number in object 3A from 1 to -1, it will load an empty backgroundless green hill with a title card: "Green hill zone zone" and after a second the game will crash, and the disassembly you are using will corrupt. EDIT: I'm not sure what it was meant to be, but in the data of the game this act is referenced as -1
Something similar happens in a sonic 1 april fools remake in spring yar- er i mean sparkling act 2 and you can keep doing by refreshing that clone spawn.
I might know why Sonic's Sprite starts glitching, if you place 2 Sonic's in a level (Using Sonic ED2 or something like that) the Sonic controlling the camera will start glitching out while the 2nd sonic will be completely fine, since they both use the same art, when they are not in the same animation one of them starts glitching (when they both stand they look fine). My theory is that the level loaded (or possibly reloaded) another sonic when you were in the "Parallel Universe" which is why sonic started glitching.
oh yeah, that happens in Sonic 3 when you place the Surfboard animation in Angel Island. Although why the game would load another player object is beyond me
"if you place 2 Sonic's in a level (Using Sonic ED2 or something like that) " Or, if running an emulator, hook something like Cheat Engine into it, find the object index you are at in object placement mode, and change it to Sonic. Moving is dmn near impossible though hahaha
Maybe… In Sonic 3 & Knuckles, looking underneath each level's loopback shows that the background tiles are stored underneath the level, and the prototype's Flying Battery background doesn't loop properly, so it starts using level tiles in the background. This also appears to share similarities with two games that released after Sonic 1; Corn Buster, and Super Smash Bros. Melee. Corn Buster has a debug feature enabled by default, where the player's arkanoid thingies are always moving upwards, which eventually reaches the end of the screen. Each level's background is long enough to wrap around exactly when the player goes up to the second loopback. Issue is, the further loopback a player heads on towards, the less stable the game will get; I remember making it to the second loopback in the first level, and the game musta been pulling from a different line of code, because then the game suddenly crashed. Super Smash Bros. Melee is only similar because Green Hill's disappearing background is similar to SSBM's Home-Run Contest arena where, if entered via the debug menu, and the player has the camera focus on Player 1, the loaded area won't refresh to appear infinite, since the game only keeps track of Player 2 by default.
Two reasons as to why I think the game crashes is that either there's to much memory being stored that the console just can't handle, or if said memory is being loaded in way to fast for it to handle and just gives up. But I don't have an exact reason to it as I'm not in an area of expertise in this stuff, not by a long shot.
Yeah, it says illegal instruction. I didn't understand what it meant exactly, but I searched and it's quite interesting. "Illegal instruction means that there's a byte in the assembled file which doesn't represent a valid CPU instruction. E.g. 0x90 is NOP, but 0xff probably doesn't map to a valid instruction. When the CPU comes to a byte it can't understand, it throws an illegal instruction exception." The text message is essentially a crash handler. Other possible messages are "LINE 1010 EMULATOR" and "LINE 1111 EMULATOR".
Super interessante, esse protótipo pode não ter muita coisa, mas o que contém de novo é bem Interessante. Me faz questionar se algum dia encontraremos o Protótipo da Tokyo Show.
Isso me lembrou de quando eu usei o Vinesauce ROM corruptor no remake do protótipo do vídeo, o jogo tava tão bugado que ao acessar a green hill zone, aparece uma mensagem rara e nunca vista antes, ela dizia "Privilege Error" e uma linha de códigos.
No. An illegal instruction happens when you either crash the game or abuse debug mode. An illegal instupruction is what happens when the game gets confused and asks for something that isnt in the games rom. So then it crashes or the game gets fucked up.

If you fly up in this act at the start, there’s some tiles and level chunks!

The game spawned another Sonic, who was cycling through different animations. That always messes with Sonic's sprite tiles
that's the thing, why would the game just spawn another Sonic out of nowhere?

I have a feeling the developers literally just copied and pasted the level layout and forgot to remove the Sonic Object and Motobug Object

Or, if running an emulator, hook something like Cheat Engine into it, find the object index you are at in object placement mode, and change it to Sonic. Moving is dmn near impossible though hahaha
You probably mean RAM editing. I'm pretty sure cheat engines don't work with emulators
srsly, these comments are encouraging me to learn more about this game, assembly programming, hex editing and other stuff like that
I guess you went so far out it started to read the background data as level data..?
