  1. Rip original disc to ISO (or obtain legal ISO).
  2. Analyze ISO contents: identify game data, FMVs, STREAM/PS2SAVE, audio formats.
  3. Extract large assets (FMVs, uncompressed audio) for re-encoding.
  4. Re-encode FMVs with ffmpeg using modern codecs/efficient settings.
  5. Re-encode audio to lossless or high-quality lossy (prefer FLAC for lossless; Ogg Vorbis/Opus at high bitrate if space-critical).
  6. Replace assets in ISO filesystem (rebuild ISO).
  7. Apply file-level compression (pack ISO into 7z/Zstd) or create a patched compressed format used by emulator loaders.
  8. Test in PCSX2 and on real hardware (if using mods like SwapMagic/SwapDisc).
  9. Distribute only patches/deltas (xdelta) to avoid sharing copyrighted ISOs.
