(Android) Obtaining the Data.rsdk for Sonic 1 & 2 - A Tutorial for Sonic the Hedgehog (2013).

This tutorial covers how to legally obtain the Data.rsdk files from the mobile remasters of Sonic 1 and Sonic 2, specifically the Android versions (for iOS, read this tutorial). The Data.rsdk files contain all of the games' assets required to both play and mod them.

1. Prerequisites

- Legally obtained copies of Sonic 1 and/or Sonic 2
- Apk Extractor
- ZArchiver

2. Extracting the APK File

It should be noted that you can easily look for an APK file for Sonic 1 and 2 online, however doing so should only be a last resort. It's highly recommended you instead download the game(s) from an official source such as Google Play and extract the APK files from your Android device that way (which is what this section of the tutorial focuses on), as this supports SEGA and their future works. It's also recommended that you pay to remove ads from the games for the same reason.

1. Open Apk Extractor, and scroll down until you see the game(s) you want to extract.

2. Tap the game(s), and the app will extract the APK file(s) into the ExtractedApks folder of your device's main storage directory.

3. Extracting the Data.rsdk File

1. Open ZArchiver, and navigate to the aforementioned folder.

2. Touch and hold down the APK file for the game you want to extract until a pop-up menu appears. Tap "View". (If you don't see View, try tapping the file instead of holding it down.)

3. Navigate into the assets folder, then scroll down until you find "Data.rsdk.xmf". Tap and hold the file down, and then tap "Copy".

4. Navigate into a folder you know you can easily access. Tap the clipboard button to paste the file into that folder.

5. Tap and hold the Data.rsdk.xmf file once more, then tap "Rename". Name the file "Data.rsdk", then tap OK.


4. Conclusion

Congratulations! You should now have the Data.rsdk file from Sonic 1 or Sonic 2 extracted on your Android device. You can use it to play the RSDKv4 Decompilation, since that's likely what you came here for.
