| The Android APKs can be opened up in an extractor program like 7-zip. 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''). | The Android APKs can be opened up in an extractor program like 7-zip.

| 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. | 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 ''Data.rsdk'' is not included in the Play Store version of the Android APK files. It is a downloaded asset, and may be extractable on a rooted Android device. It is, however, included in the XAPK distributions from third-party app stores, which can also be treated as a zip file for extraction purposes. The file will match the pattern ''Android/obb/com.sega.soniccd.classic/patch.*.com.sega.soniccd.classic.obb''. If you're using the Steam version, the ''Data.rsdk'' file is in the game's folder. |
| |
| The ''Data.rsdk'' file and videos folder should be in a folder named ''[Game Name].scd'' (i.e. ''roms/sonicretro/Sonic CD.scd/''). | The ''Data.rsdk'' file and videos/ folder should be in a folder named ''<Game Name>.scd'' (i.e. ''roms/sonicretro/Sonic CD.scd/''). |
| |
| | The ''<Game Name>.scd/videos/'' folder is optional, and is only used for some full motion video sequences, including the "INTRO MOVIE" selectable from the game's main menu. The video files added to this folder **must** be the ''.ogv'' video files from the Steam version, regardless of which platform's ''Data.rsdk'' is used. Note however that the filename case for these files will require some tweaking, e.g. ''Opening.ogv'' from the Steam game must be called ''opening.ogv'' for use with the Android data file. For reference, the Android MP4 video assets can be extracted from the zip ''Android/obb/com.sega.soniccd.classic/main.*.com.sega.soniccd.classic.obb'' and can be viewed with any compatible video player software. |
