Convert RSDK to ZIP

QUICK ANSWER
Is it possible to convert RSDK to ZIP?
Yes - RSDK converts to ZIP.

An .rsdk is a Retro Engine datapack, not a ZIP, so you can't just rename it. Extract it to a Data folder with RetroED or RSDKv5Extract, then zip that folder using 7-Zip or Windows' built-in compression.

Also to ZIP: KGL · IMAZINGAPP · LOCKER

Why convert RSDK to ZIP?

The .rsdk container uses its own indexed, sometimes encrypted layout that generic archivers can't open, so making a .ZIP is a two-step job: extract with an RSDK tool, then repack the resulting files with a standard compressor. The end result is an ordinary ZIP of the game's assets rather than a working datapack.

How to convert RSDK to ZIP

RetroED + 7-Zip EASIEST

Extract via Tools > RSDK Unpacker > Export DataPack, then right-click the exported Data folder and choose 7-Zip > Add to Data.zip.

RSDKv5Extract + 7-Zip

Run RSDKv5Extract on Data.rsdk to get the file tree, then compress that folder with 7z a Data.zip Data/ on the command line.

RSDKv5Extract + Windows Explorer

After extracting, right-click the Data folder and choose Send to > Compressed (zipped) folder to make a .zip with no extra software.

Quality & what to watch

  • A ZIP made this way is just an archive of loose assets; the game cannot load it - only a real .rsdk datapack works.
  • You cannot rename .rsdk to .zip; the container is not ZIP-compatible and must be extracted first.
  • Extract the correct file list, or the zipped contents will have generic File #.bin names instead of proper paths.

Frequently asked questions

Can I just rename `.rsdk` to `.zip`?
No. The RSDK datapack isn't a ZIP archive, so 7-Zip can't open it directly. You must extract it with an RSDK tool first.
How do I make a `.zip` of an `.rsdk`?
Unpack it to a Data folder with RetroED or RSDKv5Extract, then compress that folder with 7-Zip or Windows Explorer.
Will the resulting ZIP run in the game?
No. It's only a backup/archive of the assets. The game needs a proper .rsdk datapack, which you'd rebuild with a packer tool.
Which tool extracts Sonic Mania's `Data.rsdk`?
RSDKv5Extract or RetroED with the RSDKv5FileList.txt; then zip the extracted folder.
