Genesis Sonic 2 & Knuckles 'any%'

This project began long ago and I thought do it myself but I have learned that aid is important and with Tee-N-Tee, Aglar, WST, and Hat, could make this movie completely.


  • Emulator used: Gens 11b + Camhack + SolidityViewer + (partial)HitboxDisplay + LUA HUD for Genesis Sonic games + Predict Animals
  • Aims for fastest in-game time
  • Abuses programming errors
  • Manipulates Luck (Some time)
  • Contains Speed/entertainment tradeoffs
  • Take damage to save time

About movie

As I said earlier, this project is a long time in my head, and I was inspired when this thread started to realize the project of 'S2K ringless' (which is to be published shortly) and I could make this movie complete with these authors that helped me and let me take some excellent zones (which will also be in the movie 'S2K ringless').
I was also inspired by the movie Aglar (Sonic 2 TAS), possibly causing an update of it (already talked too: P)

Tricks and glitches

Look at the sky

This trick is difficult to carry through It. Only serves to zones where it is fighting the boss, and to fighting, there is a height limit, that however if it's jump high, it will not show on the screen and the character will disappear and the display will remain intact while you are fighting the boss. But if there is a high jump and the boss appears when the character is flying over the limit, the limit breaks and when the capsule is broken, the character can look up and lose sight of the animals, so it will disappearance or to save some frames. Only it applies in most zones, because in zones like CP2 becomes impossible to do a high jump, because I do not have a way where you can climb to jump higher and manipulate the limit.

Into the objet

This is easy to do, if there is a box attached to the wall. Knuckles makes a jump and before I fall and break the box, make a small flight to into the wall. This is done if is well positioned between the wall (left or right) and the box (Bottom side), sometimes varies the pixels to be taken to do so. Thanks to this, I can saltearme many places (This is used very often in MZ) and save me a lot of time in-game.

Level by Level comments

Emerald Hill 1

This zone has become a "multiple" work, because we have made a frame wars to optimize this level, which was achieved so far. Luckily in the loops, it could take a reasonable velocity, and disappear the display quickly to manipulate objects and move forward without frustra with the objets.

Emeralh Hill 2

Here I worked and optimized everything I could. For faster to make the loops or other shaped like Sonic's route I take, I can't get same time (in-game) in his movie, and takes 1 frame slower than Sonic's TAS. Here I applied the trick "Look at the sky" (which I explained above) and manipulate animals in the capsule for that them not jump high and do not deviate from the screen and thus make them disappear to return to normal display.

Chemical Plant 1

This is achieved thanks to the trick or glitching that was made with Sonic (Here's a demonstration (By WST)), and has performed with Knuckles and has also achieved, but not as fast as Sonic, so it takes speed a bit ahead to make glitch. I don't know because it is the reason, I have tried thousands of times as it has done with Sonic but not as fast as expected.

Chemical Plant 2

This time, I made a different segment. This is where the character is more stuck because there objects that moving that it becomes impossible to handle, for example, after the first loop to jump on the highest platform. That makes me a little time delay, but only just. Then everything normal until it reaches where the boss fight and manipule explode of boss and animals go in another direction to break capsule and save frames
This also makes losing frames at the start of the next zone, but recovers in CNZ, I don't know as I did, but I was able to recover what was lost in this zone.

Aquatic Ruin 1

In the beginning it's all pretty easy and optimal to make glitch, made in Sonic TAS. Taking or attempting to take the same speed out of the camera to not be delayed and lose speed and time (frames).
With the flight of Knuckles, it is further optimized when entering the top of the loop, and make "more fast" the process of zone.

Aquatic Ruin 2

This does not explain well as possibly Tee-N-Tee knows how to do. From my point of view, this is making the same glitches but so Knuckles left in the air to fight the boss quickly.
Are same glitches,use trick "Look at the sky" with some pauses in-game to do it faster and can regain frames lost previously.

Casino Night 1

This place is one of the easiest and best time to do it. Since it takes the lower path where you can go through the solid for easy entry into the wall and quickly finish this act.

Casino Night 2

At first, I take a leap to land on the trampoline fastly and save 1 or 2 frames. Then I make "Into the objects" trick and so we can quickly end the zone to reach the boss, and the use of manipulation of the capsule to finish this.

Hill Top 1

I took the same route as Sonic, and have taken an advantage where I can saltearme much of the lava zone to not waste time until the wall is up and passed over it without dead crushed.

Hill Top 2

Is taken a route where travels faster in some places, although there is some glitch that can be done, but I don't know yet

Mystic Cave 1

Same Sonic's route. Except for some places where I can move faster because Knuckles does not jump high, so it does not benefit me much.

Mystic Cave 2

Aglar has managed to make this beautiful zip (CP1 style) to stand a good way to defeat the boss faster

Oil Ocean 1

Same Sonic's route. This time in the beginning is pulled faster on oil.

Oil Ocean 2

This is one of the zones that cost me more to do, a matter of speed and jumps, but I've been able to optimize effort and achieve a reasonable time.

Metropolis 1

I have taken new routes and new zips, which is faster to move forward, because the level no have limit higher and lower where they can collide in this zone.

Metropolis 2

Nothing out of the ordinary ... has been manipulated to lower the platform faster, but it does not so fast and the level of Sonic, so it is slower.

Metropolis 3

It has managed to better optimize this part, beginning on the trampoline to go down and perform faster glitch along the way.
In the box it makes me slow some frames, so I see impossible, but it has been achieved.

Wing Fortress

A new discovery of a glitch that is from the beginning and Knuckles can easily pass through walls and get to defeat the boss quickly

Death Egg

Knuckles's jump is enough to attack the boss as in S2, waiting a little the first hit

Posible improvements

So far nothing. In the future I will see if there is any improvement available.

GoddessMaria: Judging.
Samsara: File replaced with a 245 frame faster file. In the future, please post updated files in the thread instead of in the submission text.
GoddessMaria: Alright. So with this one, the question I find myself repeatedly asking in my mind is the potential improvements. I've not been able to notice anything, but at the same time I'm feeling a bit off about this run. Despite that, I believe that this is good enough quality to accept this to Moons.
Spikestuff: Less than 24hours? Alright, Publishing.
