  • Emulator - Gens TEST 10
  • Takes damage to save time
  • Abuses programming errors in the game
  • Aims for fastest time
For a long time, nobody had taken it upon themselves to timeattack a Sonic game. Then came Sprint, doing Sonic 3 & Knuckles. Then came Xebra, who started doing Sonic 1 but got sick of it and gave up. Sonic 2 got a similar treatment from Hero Chaos Chao. After several exceptionally poor quality Sonic 2 speed run submissions (ranging between 30 and 40 minutes long), I decided that my first timeattack would be of this game.
So here it is, after months of hard work and a short hiatus.
Level times: (TSC records in parentheses)
  • Emerald Hill 1 - 0:18 (0:20)
  • Emerald Hill 2 - 0:36 (0:38)
  • Chemical Plant 1 - 0:17 (0:22)
  • Chemical Plant 2 - 0:51 (0:53)
  • Aquatic Ruin 1 - 0:19 (0:24)
  • Aquatic Ruin 2 - 0:38 (0:43)
  • Casino Night 1 - 0:25 (0:34)
  • Casino Night 2 - 0:55 (1:05)
  • Hill Top 1 - 0:39 (0:48)
  • Hill Top 2 - 0:48 (1:03)
  • Mystic Cave 1 - 0:28 (0:40)
  • Mystic Cave 2 - 0:37 (0:49)
  • Oil Ocean 1 - 0:26 (0:38)
  • Oil Ocean 2 - 0:48 (0:59)
  • Metropolis 1 - 0:54 (1:12)
  • Metropolis 2 - 0:50 (1:30)
  • Metropolis 3 - 1:30 (2:33)
  • Sky Chase - fixed length auto-scroller
  • Wing Fortress - 1:42 (1:56)
  • Death Egg - 0:42 (0:49)
Quirks/Glitches:
  • In Oil Ocean 2, falling into the sphere cannon after being injured by the spikes causes Sonic to gain some unusual abilities, allowing him to run and jump as if he were Super Sonic. This glitch lasts until he performs a spindash.
  • In Death Egg Zone, the explosions are replaced with animal graphics, apparently because I defeated the bosses too quickly.
Enjoy!

Wow, is this the first “serious” Sonic TAS ever made? I beleive it deserves a better YouTube encode.

That'd be this movie, actually Funny enough, the improvement to that TAS was also published earlier than Sonic 2, by about 4 days :P

The subtitle placement here isn't great. I'd start them at around 0:11 (after the transition ends) and put them at the bottom, with the second subtitle being 4 lines instead of 2. The rest is good, though, just fix that and it's good to go.

NES TAS of 2011
Subtitle positioning is absolute (don't ask me why, it's because avisynth is disgusting), and aspect ratio correction for Genesis stretches the video vertically instead of horizontally like most systems. So if you put subtitles at the very bottom, the preview uses 512kb mp4 settings so it looks ok (it's ok in that encode too), in primary mkv they are slightly out of bounds, since we don't pre-stretch primary encode. So only the SD mkv needs to be redone again. EDIT: Actually hold on, the youtube encode shows only a few minutes of duration in MPC-HC, but plays fine beyond that. I'll see how well yt decodes it.
Warning: When making decisions, I try to collect as much data as possible before actually deciding. I try to abstract away and see the principles behind real world events and people's opinions. I try to generalize them and turn into something clear and reusable. I hate depending on unpredictable and having to make lottery guesses. Any problem can be solved by systems thinking and acting.

Oh I see. The problem is that VirtualDub doesn't really show what the Modern HQ MKV shows, so I would have to use trial and error to figure it out. I'm guessing an offset of at least 1 or 2 pixels from the edge of the screen will do, right?

If you wish to sorta simulate how it looks like on the modern MKV encode, you can set handheld to true and set the subtitle positioning this way. Do bear in mind that it affects the positioning for the other encodes.

Here's the update Modern HQ encode. The subtitles shouldn't be cropped off. https://mega.nz/file/Dl9FXSaB#W0ZsEV-uhFkygLGZZKwZXOTAuofJg40dwFrpM34GZbk
