Sonic 2 Metropolis Endless Fall Glitch

This is, perhaps, the fastest of all 2D games you’ve seen which really gives meaning to „Sonic“. From the top of the screen to the bottom in just 1/30 of a second or 128 pixels per frame max. That’s how fast you can get and this is one of only 3 Sonic levels where this is possible (this one in Sonic 2 and two others in Sonic 3). There are 5 parts to this video. The first 3 parts is where I play as Sonic with Tails. The last two are as Knuckles. In the first and fourth parts, I show you how you get it set up, which requires debug. The second and fifth parts are where I perform the stunt itself. The third part is a slow-motion version of it, played at half speed. After reaching 128 pixels per frame falling, Sonic suddenly goes up at 128 pixels per frame. This is due to variable overflow. Either an 8-bit or 16-bit variable is used for fractional parts given what I see when doing this. If it weren’t for variable overflow, you’d have seemingly unlimited speed. It takes just short of 10 seconds to get to 128 pixels per frame. The screen only scrolls at 16 pixels per frame which is far too slow to keep up with this.

Trying to keep up with the Fastest Falling Human Being in the Planet…at 160mph Average Terminal Velocity for my Crazy-Super-Loco and „Cement Block“ Friend, Daniel Perez….Notice that we pretty much are „wrestling“ our way out of the plane, during the fall…and beyond…. Fun Times….Live to Fly Another Day….

  1. thumps up if you were moving your head to the slow-mo music at 2:40

  2. lol…

  3. SEG-

  4. @ulillillia And if he were to land on a solid object in game, he’d be perfectly fine. -_-

  5. @ulillillia well yeah,but im saying it hypothetically

  6. sonic just passed the speed of light. And ulillillia knows a loooot about the genesis sonic games’ programing. He converted a video game fall into a real fall, including factors such as acceleration time and increased gravity. Thats just awesome.

  7. Given that it takes 594 frames to accelerate to 128 px/fr and that gravity is apparently 4 times higher than normal, this points to about 38,000 pixels for the falling height. I don’t know the exact scale to convert to real world units, but I’m assuming it’s around 5 cm per pixel. With that, you’re looking at a fall spanning 1.9 km (1.2 miles).

  8. SONIC IS FALLING OFF THE EMPIRE STATE BUILDING

  10. @ulillillia Okay, that sounds pretty cool. Thanks!

  11. Debug mode is a special otherwise hidden mode in the game that allows you to, to a limited extent, create miniature levels using the various game objects. Yep, you can place them anywhere you want. Look up one of my „fox splasher“ videos and you’ll see what I mean. Find that same spot in the game and you’ll see things are much different. It’s a lot of fun too and it’s exclusive to the Genesis era games (no later than Sonic & Knuckles’ release). See GameFAQs for more detail.

  12. What is debug mode?

  13. No, I didn’t replay the video. Try it yourself. This is even possible without debug, but it can only be done in Desert Palace and it takes a while to do that because it takes very precise jumping and use of the spin dash.

  14. your not falling endlessly, you just replayed the video

  15. The only way is Knuckles in Sonic 2.

  16. how do you get the rings monitor using the debug?? i just get the 2 arrows one and i can only use it once (break it)

  17. @SmokieRSWC „I HATE SCYTHERS!“

  18. It’s Sonic 2 and Sonic 2 & Knuckles. It makes no difference what system it’s on – Metropolis and debug mode are needed. Don’t want debug mode? It can be done in Sonic 3′s Desert Palace, but only with Tails.

  19. what game are you playing this on?

  20. I FOUND OUT THIS GILCH BY MYSELF TOO!

  21. The camera only scrolls at 16 pixels per frame at the max, extremely slow. Sonic 3 & Knuckles caps at 24 instead, still rather slow and easy to get. 32 is be better, but even then, there are many places it can be reached without debug mode or Knuckles’ gliding – past Carnival Night 2′s boss (requires Tails to lift Sonic), Ice Cap’s mountain (Knuckles only), Mushroom Hill 1 and 2, and Lava Reef 2 (just before where Knuckles is encountered – take the big fall to death) are some examples.

  22. Only in Sonic 3′s 2-player mode. Play Desert Palace with Tails. See my „Sonic’s fastest speeds“ video for Sonic 3 on how to do it. It does take great skill though but it’s entirely doable.

  23. Can you make this happen WITHOUT Debug Mode?

  24. Wow hes so fast he can fall faster than the camera

  25. @SmokieRSWC Ok. Just makin sure you weren’t some Pokemon fanboy lol
