The reason why the 255 is the highest number for Sonic's life counter is because it support 8-bit integer. If we go below 0, the integer underflows to 255, and if we go beyond 255, the integer overflows to 0.

It also happens to sinistar as well. You basically die twice when you have one life left. And after that, you set it back to the max amount of life the game can handle.

There is 2 types of 8bit integers. Unsigned and signed. Signed lets the value be negative(range -128 to 127). Unsigned ranges from 0 to 255. The CPU of the Sega Mega Drive supports 32-bit integers that goes all the way up to 4 billion!(Unsigned. The signed one goes up to 2 billion)(also this is just an addition)

The spike glitch has always been really interesting to me. Obviously it was un-intended, as they fixed it in later games, but the reason it happens is kind of funny. In Sonic 1, you don't gain i-frames until after landing. Once hit, Sonic enters a state where enemies no longer collide with him, then once he lands he enters his normal state with i-frames. However, the spike uses the same collision as other scenery objects, so it's the 1 thing in the game that can damage you even if Sonic is in his special falling state, because naturally they didn't want him falling through the ground. I am not sure exactly how they fixed it, but either checking the state if he does end up colliding, or starting the i-frames right away but leaving the timer at 1 until he lands are both potential solutions. To know which one they used I guess you'd have to pay attention to if sonic blinks after getting hit before landing in later games.

The reason why on some emulators like Gens, Sonic appears on top of the ribbon on the title screen is due to the sprite limit being turned off, which is what cuts off a part of Sonic and thus prevents him from appearing on top of the ribbon.

the reason gaining +1 life from 255 effectively brings you to 256 is because when you're _at_ 0, losing a life brings you back down to 255, so you effectively have 255+1=256 lives. you normally can't be at 0 because hitting 0 lives via a death triggers a game over, but since you're instead hitting 0 _without a death,_ the game never bothers to check if you should game over, so you don't.

In marble zone you can actually push blocks by rolling into them so you don't have to hold the direction button. Don't know if it's a glitch or intentional. There's also something in spring yard that I like to call the inifinite skid were you if run down the hills you can hold sonic's skid animation with the waving hand indefinitely even as you bounce around on bumpers and ending when you even land on a solid platform.

14:41 Tap/click Read more for full explanation The reason why Sonic can gain 255 lives is because of an integer underflow. So if the life counter is 1 (Internal value is 1-1=0) and you get Sonic to die twice, the Game Over check is skipped, as the game checks to see if the internal value is 0 or not, but that check happens _after the death animation is finished and the live counter has finished decrementing the internal life counter_ This bug also happens in Sonic 2 (MegaDrive/Genesis) Chemical Plant Zone. So 1-1-1=-1, but since the life counter is an 8-bit unsigned integer (positive numbers + 0), it will wrap around to 255, then decrement by 1, which means the internal value is 254. For Sonic getting a life increments it to 255, but making Sonic to get one more life resets the internal life counter _back to 0_ so that means if Sonic lose a life when his life counter is 0, all 256 tries are essentially wasted, as the game checks if the external life counter is 0 (internal is 255) or not when decrementing (incrementing does no effect) before setting the GameOver flag in the game after the death animation is played and the internal counter is completed the decrement process. It's the same thing with Pacman's Level 256 glitch. P.S. I'm speaking from decino's perspective.

@whiteeeveeangel 2 жыл бұрын

yes and no. It has less to do with with it being an 8-bit integer and more with hexadecimal counting. Instead of normal decimal that most people work with (0-9, 10 unique characters for each place, thus the reason it's called "deci"mal, since deci is 10 in Latin), hexadecimal, logically, has 16 unique characters, 0-F. This is where the 8-bit integer comes in. Most life counters in older games were 2-digit (0-99, which is 100 unique values (1-99 plus 0), but because the coding behind a 2-digit number requires 2 bits and those bits are written in hexadecimal, they can technically go between 0-FF (usually with a coded limiter to prevent earning more than 99, but that's beside the point). FF in hex code happens to convert to 255 in decimal (16x16=256, just as 10x10=100 in decimal), which is why you see so many things in older games cap off at 255, but just like decimal's 0-99 is actually 100 unique numbers, the 0-255 of hexadecimal is 256, the obvious 1-255, as well as 0.

7:03 I have a hypothesis on why this happens and I don't know a lot about how sonic 1 works so if I get something wrong then that's why. Ok so the background changes how it moves with sonic and goes up down left and right accordingly. So what I think is happening is that when you die in water something in the code messes up and freezes the background until the level restarts. So when you get a game over it freezes the background and doesn't reset the background because the level never reset. Yet again I'm not coding expert and don't know much about how sonic 1 works so if I get something wrong you can comment it or propose a different theory on how it happens.

The Spike and Drowning Glitch can be explained by Programming. When Sonic Drowns, the game says "Play this Animation." Which is Sonic's Drowning Animation. This Animation overrides the "Hold Pole" Animation. So far, so good. The Drowning Source code says "Take One life from Player counter." Still good. BUT. Here's where the mess happens. While the Drowning Animation happens, the game is ALSO doing the "Push Sonic" Effect. Which, causes the Glitch. As Sonic is NOT told "Do NOT move Horizontally while dying." As that Condition is, almost never gonna happen, Except in this case. So, Normally Sonic would play the "Floating" Animation when being pushed. BUT, we have a conflict. As the Drowning Animation is in action too. Then by pressing A, we interrupt the Drowning Animation because, Sonic is moving Horizontally. Then, we hit Spikes. Because we have no Rings, that means "Die." So, now, we have the game with a "Stack" of things to do. Sonic Drowning Code says "Take one Life." AND, the Spikes with Zero Rings says "Take one Life." We hit a problem. One Minus Two, is, negative One. BUT, the Integer is not a SIGNED value. AKA "Can be negative." Why? Because if lives ever reached Zero, Game Over. So why would they developers care if the value became negative. That, won't happen, right? It, does. So. The game says "Well. I can't have Negative Numbers. So logically, the next number is, 255" This is referred to as a Buffer Overflow. This kind of thing happens in other games too. Like Twilight Princess on the Wii where the game says "Horse name can be up to 8 Characters." BUT, if you were to manually edit the save file and make it longer then 8 characters the game won't stop, and could load, 3rd party code. That is a Buffer Overflow Exploit. Fun times with limited hardware.
