  • Aims for In-Game Time instead of Real-Time
  • Takes damage to save time
  • Heavy glitch abuse
  • Uses death to save time
  • Uses the hardest difficulty


So, the original idea was simply to try and get the original TAS to sync on console. As I was skimming through the inputs, I found a stray frame in Secret Base 2 and ended up discovering a few more frames due to a resulted desync. This lead me to coming across even more improvements than anticipated.

Stage by stage comments

Secret Base 2

A few frames were saved from an optimized jump and glide.

Casino Paradise 1

One of the bigger improvements as there was a route change. Rather than take the full top path, I take the path towards the Running Shoes monitor. I had originally dismissed this for years as it didn't seem faster. It starts off slower than the current route, but quickly picks up about halfway.

Casino Paradise 2

More or less the same route as the original movie, but more optimized.

Ice Mountain 1

Small optimizations here and there.

Ice Mountain 2

Minor optimization entering the boss.

Angel Island 1

Rather than resort to one long spindash, I utilized more glide cancels to reach a more favorable position.

Angel Island 2

Same as the previous run with some better optimization.

Egg Rocket Zone

Minor cleanup at the end of the act.

Cosmic Angel Zone

The other one with a significant time save. In addition to gaining frames by optimizing jumps half way, the bulk of the time save came from the better damage management in the boss fight.


I decided to try a few ideas to gain more speed after finishing the Sonic 1 boss without sacrificing time. One idea being spindashing from ground level and jump up. The other one, the one used in this run, utilizes a 10-rev spindash at the edge of the first platform and punch at the edge of the second one to reach the collapsing platform much faster. The rest is essentially the same.

ThunderAxe31: Claiming for judging.
ThunderAxe31: Accepting as improvement over the current publication.

EZGames69: Processing...
ThunderAxe31: File replaced with a resync for GBAHawk 2.0.2. No changes to actual gameplay, so judgement stands.
