Sonic CD on PC: RSDKv3 Decompilation

RSDKv3 Decompilation is a complete decompilation of Retro Engine v3 that lets you run Sonic CD (the 2011 release) natively on Windows, Linux, macOS and Android. Compared with the official PC version it offers a sharp pixel-perfect display, fully remappable controls via settings.ini, window shortcuts and support for the mobile and updated scripts; compared with the mobile versions it uses the PC rendering backend and supports palettes (such as Tidal Tempest’s water). It also includes a built-in mod loader.

Without the assets from an official release it will not run: you must buy or officially download the game (Steam, Epic Games Store or Sonic Origins, Nintendo Switch, iOS or Android) and extract its data. GigaROM hosts neither the engine nor the game; the download comes from the official page.

• Windows (x64 or x86), Linux, macOS or Android.
• The assets from a legally obtained official release of Sonic CD (you do not need to run it, only its data files).
• FMV videos are only supported from the original Steam release; mobile and Origins videos do not work.

1. Download the latest release from the official page (“Go to official project” button).
2. Get the data files from your official copy of Sonic CD (there is a guide on rsdkmodding.com) and place them next to the engine.
3. Open the engine and play; adjust controls in settings.ini.

• It does not run without the official assets.
• FMV videos from the mobile and Origins releases are not compatible.
• The repository’s license is not a standard one: check the license file.

If your computer does not meet the requirements, you do not have the exact version the port asks for, or you prefer the classic route, you can play the original with a console emulator: see emulators and its install and setup guide.
