The Fire Emblem Echoes: Shadows of Valentia Undub is a fan-made modification of the 2017 Nintendo 3DS tactical RPG. It is designed to restore the original Japanese audio to the localized Western version of the game. While the official release includes a widely praised English voice cast, the "Undub" is a popular choice for players who prefer the original Japanese performances or want a more "authentic" anime-inspired experience. Key Features of the Undub Version

Technical feasibility

• File structure: 3DS games store voice and audio files in packed archives within the ROM filesystem (NCCH/CXI, RomFS, ExeFS). Audio is often in common formats (e.g., BCWAV/BCSTM) or proprietary containers.
• Process (high-level):

  Remake Status: It is a complete remake of the 1992 Famicom game Fire Emblem Gaiden.

  • File size approx. 2.1 GB (larger than the 1.7 GB official release due to high-quality JP audio).
  • No “English Dub” option in settings – Japanese is hardcoded.
  • Restored vocal version of Infinite Horizon playing on the title screen after boot.

  Mila’s Turnwheel: A mechanic allowing players to rewind actions during battle, which has since become a staple in newer titles.
