Jon Burton, founder of Traveller's Tales and a leading figure behind many of its games, has just released a patch for Sonic 3D Blast (or Sonic 3D Flickies' Island, if you're living over in Europe) title "Sonic 3D Blast: Director's Cut." This patch includes multiple improvements over the original game, touting better controls, a world map, and Super Sonic, among other features.
Prior to release, Burton has documented the development of the patch for quite some time, originally announcing it in a 25,000 Subscribers video on his GameHut YouTube channel. Improvements to the game were announced as development gradually progressed.
The patch is available (in XDELTA format) on here. Do keep in mind that this is a patch, and does not contain any of the original ROM data.
Happy playing, and a big thanks to Jon Burton for making this all possible!
