Shin Megami Tensei Iv -undub- 3ds -decrypted- Rom Official

| Component | Description | |-----------|-------------| | | 3DS titles are encrypted with a combination of AES‑CTR and RSA using per‑title keys stored in the console’s secure module. The keys differ per region (e.g., 0x00040000 for US, 0x00048004 for JP). | | Dumping | To obtain a clean copy, a home‑brew tool (e.g., GodMode9 , 3DShell , FBI ) reads the cartridge’s NAND and writes the raw binary. The dump includes a header ( NCCH ) that flags the encryption status. | | Decryption | Tools such as 3DScrypt , Decrypt9WIP , or Citra’s built‑in decrypter (when running the dump through the emulator with proper keys) strip the encryption, outputting a decrypted NCSD/NCCH structure. The result is a set of ARM9/ARM11 binaries , exefs , romfs , and asset archives (e.g., .szs compressed files). | | Undubbing Process | 1. Identify voice files – In SMT IV they reside in romfs/voice/jp/ as .bcwav and .bcstm . 2. Remove or replace – Deleting the directory or swapping it for a placeholder reduces size. 3. Re‑pack – The modified romfs is re‑compressed ( szs tools) and the NCCH header is updated. 4. Re‑sign – The final ROM must be signed with a valid title key (or a dummy key if used only on emulators). | | Resulting Size | The original US version is ~1.05 GB. After undubbing, the ROM typically shrinks to ~970 MB , a ~7 % reduction. The smaller file loads marginally faster on low‑end 3DS hardware and on PC emulators such as Citra. |

When Shin Megami Tensei IV was released in the West by Atlus, it featured a high-quality English dub. However, many fans prefer the original Japanese performances (featuring legends like Shintaro Asanuma and Yuki Kaji) to better match the game’s Tokyo setting. Since the official Western release did not include a dual-audio option, the community created the "Undub" patch to offer the best of both worlds.

The SMT IV UNDUB did not appear overnight. It was a labor of love by the romhacking community, primarily users on forums like GBAtemp and Heroes of Might and Magic (HCS) forums. The dump includes a header ( NCCH )
