Sonic Forever: The Epilogue Expansion

By KarlEmerald


Welcome to The Epilogue Expansion, a mod for Sonic Forever that adds brand new art, music, and characters. Journey through South Island once again as Mighty or Ray, or perhaps pick someone you're familar with already and see the new art. All characters are now in the style of Sonic 1, so no Sonic 3 Knuckles or over colored Amy.


As mentioned before, every character has been visually overhauled. Sonic has some tweaked and edited sprites, along with some new, customizable animations. Tails, Knuckles, Amy, and Super Sonic have been converted into the Sonic 1 art style and now fit alongside the blue hedgehog. The three even have brand new palettes to boot, they are also customizable.


  • Hammer drop and wall jump as Mighty The Armadillo
  • Soar through the air and attack with your tail as Ray The Flying Squirrel
  • A brand new options page has been added to customize your experience. Palettes, animations, music, and moves are customizable.
  • The Sonic Team screen now displays the DeltaConduit logo along with a little animation that is randomized everytime. There are about 20 animations, can you discover them all?


In order to play the mod with your current save data, you need to bring over your save data into the mod. In order to do this, you would need to:

  1. Copy the SData.bin file located in the main Sonic Forever folder.
  2. Paste the SData.bin into the folder of The Epilogue Expansion mod.

Overall, we hope you enjoy this mod. This mod started as a simple skin mod, and it has grown to be something more, with even more to come. Have fun!!!

Sonicfan101 @ 2023-10-24 09:48:56

Does this work on android, it just crashes

WorksOfMagic @ 2023-10-27 02:03:25

According to a reply one of the dev team members did on the REMS Discord, the mod has yet to be tested on Android. Thereforew even if it did work, it'd still be missing key touch control functions.

Probably, instead of the game crashing, there should be an Android screen and how to fix it, just remove this mod

Sonicfan101 @ 2023-11-02 08:51:41

Yeah they should

BTW I saw a YouTuber who made a tutorial how to run it and it HAS the touch controls

Souplike @ 2023-10-24 14:33:55

It back!

ok, but for real, the extra characters and options are all really great. Loved playing as Ray specifically. Good job and keep it up guys. (also Xan did a great job with the thumbnail artwork)

I don't know how to play with the mod on Android without the data.rsdk file or without the sonic forever mod... Could you by any chance help?

DenverMoon @ 2023-11-03 08:20:47

I have the data.rsdk file and the sonic forever mod and it just crashes for me when I try to start a level with this mod

Sockmistress @ 2023-11-01 11:54:24

Is it just me or does combining this with Karl's unique act palettes and act tracks mod change the music?

DenverMoon @ 2023-11-03 08:20:14

Anyone know how to play this on android?

resett @ 2023-11-15 13:47:56
