This run of Sonic The Hedgehog 2 consists of collecting all the Emeralds and getting the true ending (with Super Sonic). Also consists of Few times saves in some zones and beating the previous times. This run also finds new gltiches and zips that were never seen in previous runs.
Game objectives
- Gens11b with Camera Hack and Solidility display.
- Contains speed/entertainment tradeoffs
- Aims for in-game time instead of real-time
- Takes Damage to save time
- Forgoes time-saving glitches
- Genre: Platform
Now, before I say anything. Just to clarify, we used inputs from the Previous Movie by Aglar and Zurggriff. Credits go to them for the movie inputs as well. You may ask, why 100 percent of Sonic 2. This game never had a TAS of 100%. So me, Shiro Paradox decided we should do a 100 percent TAS of it.

General Information Relevant To The Submission
The following information is not new to speedruns of this game, rather, it is here for convenience.
- The game has a hidden in-game timer that counts the frames. It does not increment during lag frames or while the game is paused.
- On horizontal ground, Sonic will lose speed when rolling. While holding forward when running, Sonic will maintain speed. When traveling down slopes, Sonic accelerates faster while rolling than running. Transitioning from rolling to running is done by jumping or falling off the ground.
- Sonic will lose horizontal speed if the vertical speed is upward and less than 4 pixels per frame. This is avoided when possible by jumping from slopes that give Sonic a downward vertical speed or by bumping a ceiling.
- Spindash release speed is controlled by how many times the buttons A, B, or C are pressed and how long the spindash is held before being released. The first button press sets the held spindash speed at 8 pixels per frame. Subsequent button presses raise the speed by 1.5 pixels per frame and each frame the spindash is held lowers the speed by 1/32 of the held speed value. The range for spindash speed is bounded to a minimum 8 pixels per frame and a maximum of 12 pixels per frame and the release speed only occurs in increments of 1/2 pixel per frame. Thus, it takes 6 button presses to release a maximum speed spindash.
- Zips occur when Sonic is inside solid terrain. The game ejects Sonic at speeds up to 32 pixels per frame in the opposite direction that Sonic is traveling. This is useful for performing a level wrap but is also good for just going fast.
- Special Stages have a little thing in them, they have lag frames in them. The devs added lag frames because if there were no lag frames in the special stages, you wouldn't control Sonic/Tails properly and the special stage would move fast. They also changed the aspect ratio of it as well.
Stage By Stage Comments
Emerald Hill 1
Here in act 1, I got few things I have to say. There are lot of different routes I could have chosen, but the fastest and the most suitable route was the one I chose. This is nearly the fastest and most optimized route and ring planning I chosen. After getting the first emerald, I head towards the speed monitor to gain and maintain my speed. This route wasn't as optimized as it should but it is still the fastest way to get to the 2nd checkpoint. With that out of the way, we'll just slide our way to get the 2nd emerald. Now the 3rd checkpoint; this one was the most optimized route I have done. There are 2 routes, the loop de loop one and the above the loop one. The loop de loop one was 5 to 6 seconds slower due to the ring placement and not enough rings to get to the checkpoint. The other route that I choose here had a better ring placement(meaning it had few ring boxes). Now that the 3rd emerald has been collected; We can now finish the stage as normally.
Emerald Hill 2
The route I originally choose to begin with had less rings (about 3 to 2 rings). But by the power of 2 players, I managed to get Tails to get extra rings in the bottom path of the level, where the speed shoes monitor is placed. After getting the 4th emerald, I headed towards the left, where I was greeted with few rings and a ring monitor. After getting the monitor and passing the loops with great epic ness; I was once greeted with 2 pathways. If I chose the upper path, I would have more rings but reach the checkpoint late, but if I chose the bottom path I would have less rings but reach the checkpoint early. That being said, I choose the bottom path because yes. But wait; I am 3 rings less than to get the stars to appear. No problem, I'll use Tails to get the 3 rings that were floating where the ring monitor was. After getting the 4th emerald, I immediately took the top path as it had plenty of rings. After getting the required amount of rings, we get the checkpoint, enter the special stage and finish to get the sixth emerald. Now that we have 6 emeralds, we can know beat the bo- nope we have 1 last emerald to collect. After collecting the rings that had the same route as before, I managed to get over 50 rings, beat the special stage and collect the very last Emerald. Now Sonic can be Super Sonic. But we wont use Super Sonic for now as we have to beat the first boss.
Chemical Plant 2
This zip was found by CubbyCubbyCat at the Classic Sonic Speedruns, they found out that it is possible to get a time save in this zone by going to the top path and using the blocks to make Sonic upwards and being at the very edge of it to get to the zip area. Forgot to mention, that part doesn't crush you. So after that investigation, Tee-n-Tee found an even better route and it was insane to begin with. There is a part of the level that is slightly open and that part, you need to make the game to think that you're on the top path instead of the downwards. With that in mind, the loop section would be open and you'll be able to go in that area without the wall stopping you. With that 2nd clip done, there is a 3rd clip that you have to do very precisely. Basically you have to go to the loop and make the angle where you're going to the right with sufficient speed, then you can or have to clip through the loop and meet in a ground where you'll find emptiness. With the right speed and subpixel (I believe subpixel is included), you can clip through the wall/block and reach the boss. This trick saves a lot of time. Done by Tee-n-Tee!
Casino Night 1
Now, this strat was found by Joeybaby69 over on CSSs and he found out that you zip through the end of the stage by going to that position and ducking down. Whilst ducking down, make sure you jump at the right moment with the right subpixels. Other wise, you'll either die by the blue block, or you'll die at the bottom of the stage or you'll get stuck. This strat is pretty easy and tough at the same time. Me and Kaan55 got the same time :D.
Metropolis 1
This strat was again found by Joeybaby69, he found out that, you can get at the very last pixel of the crushers and stand on it. With that in mind, if you duck and make the camera pan down and as soon as the crusher is about to go up, quickly jump on it or walk on it at the very last pixel. And while the camera is moving in the Vertical Position, you now have slope glitch and you can now jump and go downwards to the path where the curve section is and zip through the level with great ease. Done by me.
Sky Chase
Honestly I don't even know how Shiro got 1 frame time save from it. Maybe because of Super Sonic, which we now used only in this zone.
Wing Fortress
Now, before you ask I don't know what happened here. Shiro lost time here due to the disappearing platforms. I think and for sure think that those platforms were on power on cycle. So maybe just our luck.
Improvements
Currently, We don't know. However, accepting improvements if we find.

feos: Claiming for judging.
feos: The game doesn't dictate when you have to enter the bonus stages to collect the chaos emeralds, it just sends you there if you touch a checkpoint while having 50 rings, which is possible in any level, and as this run shows, in the same level too. Since there's no in-game limit on where you need to collect the emeralds, we don't want to impose artificial limit that makes the run more different from any%, because full completion aims to be the most objective goal, together with fastest completion.
While most of gameplay in this movie is similar to [3584] Genesis Sonic the Hedgehog 2 by Zurggriff & Aglar in 17:40.08, we don't have a global site goal to have less content as long as it's unique, at least not anymore. As I said in this post and it's recently been made official: We want to embrace what our content creators are interested in doing, which will make them happier and they will contribute more cool movies. We don't want to tell them what to do by limiting which categories we want to showcase on the site. It doesn't make people happier when they don't feel that our obsoletion or rejection is natural and makes sense.
So as long as there's content difference in different goals eligible for Standard - for example in this run getting all the major collectables gives you better ending - we will not demand them to be "different enough" to be published side-by-side like we do with Moons.
Accepting as a new branch.
