The Nintendo 3DS version of Sonic CD 2011 3DS has been revamped, known as Sonic CD 2011 3DS Redux. It is a new port specifically designed for the 3DS console, utilizing the hardware version of the decompilation. The game's graphics are powered by Citro3D, while the audio is supported by SDL 1.2 and other standard 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 the most recent decomp code base (as of Feb 2023)
Runs full speed on both O3DS and N3DS!
Stereoscopic 3D support
No laggy/slow special stages
(Hopefully) less crash-prone than the other existing 3DS port
Remappable (keyboard) keys in settings.ini (Uses bitmasks from libctru)
And just like the other port, dev menu can be accessed at any time by pressing SELECT

SUPPORT THE OFFICIAL RELEASE OF SONIC CD

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.

Setup

You need to dump the DSP firm before running the game, otherwise there will be no audio.
Using Data.rsdk from the mobile version is highly recommended; see known issues below for reasons why.
Just copy SonicCD.3dsx (or install SonicCD.cia) and Data.rsdk to /3ds/SonicCD/ on the SD card.
Don't copy over an existing settings.ini; this might result in unexpected issues (i.e. no input). Just let a new settings.ini be generated on first startup before modifying anything in the config.
FMVs are currently unsupported, so don't bother copying them. You'll only need the Data.rsdk for now.
Similarly, mods are temporarily disabled as there is currently a linker error when trying to build the relevant code (undefined reference to pathconf in a part of std::fs)

Currently Unsupported

FMVs
Mods (linker error when trying to compile the relevant code (undefined reference to `pathconf` in a part of std::fs))

Screenshots

Known Issues

When using non-mobile Data.rsdk, the floor in special stages is graphically broken (no LOD tiles?).
When using non-mobile Data.rsdk, Tidal Tempest is completely graphically broken (black screen/garbage).
When using mobile Data.rsdk, the pause button is mapped to the B button, and pausing doesn't work at all in special stages.

FAQ

Q: Can the D-Pad and Circle Pad both be mapped to movement at the same time?
A: Not yet. For now, choose one you feel most comfortable with and modify the keyboard mappings in settings.ini, using the key button masks defined in libctru.
