Why convert RSDK to OGG?
No transcoding is needed: the soundtrack ships as .OGG files packed inside the .rsdk container, and extraction simply writes them back to disk at their original quality. The audio you get is bit-for-bit identical to what the game plays.
How to convert RSDK to OGG
RSDKv5Extract
Run RSDKv5Extract on Data.rsdk to dump the whole file tree, then open the Data/Music/ folder to find every .ogg track.
RetroED
Use Tools > RSDK Unpacker with the matching file list and Export DataPack; the .ogg music files appear under Data/Music/ in the exported folder.
Oggextract EASIEST
Drag and drop Data.rsdk onto the Oggextract executable and the .ogg files are written out beside the game directory, no file list needed.
RSDKv5_Extract_Plus
A maintained fork of the v5 extractor that unpacks Data.rsdk for newer builds; the music comes out as .ogg in Data/Music/.

- The
.oggfiles are copied verbatim, so there is no quality loss - but you also cannot make them higher quality than the game shipped. - Some music files loop in-game via metadata (loop points); the raw
.oggplays start-to-end without those loops. - These are copyrighted game soundtracks; extract for personal use only, not redistribution.
