Sonic Retro

These emulators, part of the Ports section of Batocera are enhanced versions of the original Sonic 1, 2 and Sonic CD for the Sega Megadrive/Genesis and CD32.

They require additional game files from the recent iOS/Android ports to setup the games.

This port requires the .rsdk files from the Android or iOS versions of Sonic 1 & Sonic 2.

The Android APKs can be opened in 7zip. You need to extract the file /assets/Data.rsdk.xmf and rename it to Data.rsdk and place it in a folder named [Game Name].son (for example Sonic 1.son).

For Sonic CD, you can use the files from the Android, iOS, or Steam versions, as well as the video files from the Steam version.

The APK can be extracted the same way. If you're using the Steam version, the Data.rsdk file is in the game's folder. The rsdk and videos folder should be in a folder named [Game Name].scd (i.e. Sonic CD.scd).

Batocera will auto-select the port to use based on the folder's extension - sonic2013/rsdk4 for .son folders, or soniccd/rsdk3 for .scd folders.

Selecting the wrong emulator will be ignored as the two versions are not compatible. The options are slightly different between the two, so you may need to manually select the emulator to change them.

The dev menu option is needed to run mods.

Here are the checksums of some data files that have been reported to be working.
