Sonic 3D Blast is an isometric platformer/collectathon by Traveler's Tales for the Sega Genesis/Mega Drive.

General Info:

In-Game Objectives:

This is a fairly straight-forward run. The game is pretty well put together and doesn't include much in the way of exploits, clips, glitches, etc. There are 2 instances of intentionally taking damage. There are no deaths. No use of Level Select. Flickies can be grabbed by Sonic or by other Flickies already following Sonic. The objective of this TAS is to collect 7 chaos emeralds while progressing through the game as fast as possible.

Movement

Movement optimization was key. I ended up doing a lot of experiments in addition to referencing other work done in the game. I have a full google doc here, but the TL;DR version is as follows:

Emerald Route

This category requires collecting the 7 Chaos Emeralds, which are found on a successful completion of Special Stages. There are 20 different instances for which Sonic can enter a Special Stage within the game. Only needing 7 of those, we needed to route the best viable opportunities to do this. In order to enter a Special Stage, Sonic must collect 50 rings and take them to Knuckles or Tails. This route was determined by figuring out which entrances would take the least amount of time loss versus completing the stage normally, needing at least 50 rings within the routing and having a convenient access to Knuckles and/or Tails. The Special Stage entrances used in this route are:

Note: The Times for these stages are slower than IL World Records due to the fact the ILs of this game do not include emerald routing.

One additional tech used for the emerald routing is Freed Flicky Flagging (found and named by Zurggriff). Not known if this mechanic was intentional, but it allows Sonic to automatically collect any Flickies that are freed from enemies upon exiting a Special Stage. This is seen in Diamond Dust 1 and Diamond Dust 2.
