Sonic the Hedgehog 2 (Mobile Decompilation) is a cartoon side view platforming game in the Sonic the Hedgehog series. It is an open-source decompilation of the 2013 Retro Engine remaster of Sonic the Hedgehog 2 originally developed by Christian Whitehead and Headcannon and published by Sega for Android and iOS devices. It has been ported to various platforms by Rubberduckycooly and other contributors.
The 2013 Retro Engine remasters of Sonic the Hedgehog 2 and Sonic the Hedgehog were initially developed for Android and iOS devices. They became ad-supported and free-to-play in 2017 with other Sega Forever branded apps, but unlike the 2012 Retro Engine remaster of Sonic CD, it remained exclusive to mobile platforms for many years. Rubberduckycooly, along with assistance from RMGRich, have developed this open-source decompilation port to allow the game to be played natively on other platforms but requires the Data.rsdk file extracted from the mobile version's APK to run. The initial Windows release of the decompilation port was released on January 17, 2021 and a fork for macOS was also released by Sappharad. The decompilation port initially only featured a basic developer interface to navigate through the game's menus and settings and it also introduced various issues not seen in previous releases of the game such clipping through solid objects and graphical corruption issues. Many of these issues has been addressed in later updates of the decompilation port.
The decompilation port currently features the ability to toggle screen filters, configurable settings through its configuration file similarly to Sonic Mania, and features a built-in mod loader. An official port of the 2013 Retro Engine remaster is featured in Sonic Origins.
