This is a brand new 3DS port based on the HW version of the decompilation. It uses Citro3D for the graphics backend, SDL 1.2 for the audio backend, among the usual dependencies.
Note: Please be aware that the load times for Sonic CD 2011 3DS Redux remain unchanged and are similar to those of other 3DS ports, which can range from 8 to 15 seconds on O3DS. However, N3DS users may experience slightly improved load times. Besides that, this version of the game should be a relatively smooth and trouble-free port.
Features
- Built on recent decomp source, as of Feb 2025.
- Both Old and New 3DS supported.
- Fast hardware (GPU) rendering by default.
- (NEW) Software renderer supported, but slow special stages on N3DS, and slow in general on O3DS.
- (NEW) FMV playback (Currently slow on O3DS and choppy on N3DS, use ffmpeg to scale down OGVs).
- (NEW) Mod support, set up and install them as you normally would.
- Stereoscopic 3D support (hardware renderer only).
- Remappable keys in settings.ini (uses bitmasks from libctru).
- Access dev menu at any time by pressing SELECT.
Installation
Support the official release
Without assets from the official release, this decompilation will not run. You can get an official release of Sonic CD from:
- Windows:
- Via Steam, whether it's the original release or from Sonic Origins
- Via the Epic Games Store, from Sonic Origins
- iOS (Via the App Store)
- Android:
- Via Google Play
- Via Amazon
- A tutorial for finding the game assets from the Android version can be found here.
Even if your platform isn't supported by the official releases, you must buy or officially download it for the assets (you don't need to run the official release, you just need the game assets). Note that only FMV files from the original Steam release of the game are supported; mobile and Origins video files do not work.
Instructions
- Dump the DSP firm from your 3DS, make sure it's at
sdmc:/3ds/
. This is necessary for audio to work. - For the best experience, use Data.rsdk from the official mobile version and place it at
sdmc:/3ds/SonicCD/
. - For the best experience, copy the decompiled scripts from here to
sdmc:/3DS/SonicCD/Scripts/
.- Make sure to set
TxtScripts
in settings.ini totrue
after doing this.
- Make sure to set
- (Optional) To slightly improve loading times, extract Data.rsdk contents to
sdmc:/3ds/SonicCD/Data/
.- Make sure Data.rsdk itself is removed from
sdmc:/3ds/SonicCD/
or setDataFile
in settings.ini to blank.
- Make sure Data.rsdk itself is removed from
- (Optional) For FMV playback, copy the
videos/
folder from the original Steam release tosdmc:/3ds/SonicCD/
.- To ensure the best playback performance, scale down the OGV files to 400x240 using ffmpeg:
ffmpeg -i input.ogv -s 400x240 -c:v libtheora -q:v 7 -c:a libvorbis -q:a 4 output.ogv
- (Optional) To set up mods, place any mod folders into
sdmc:/3ds/SonicCD/mods/
.- Also copy the decompiled scripts as instructed above if you haven't already, as most mods require them.
