Bloodborne v1.09 DLC Mods (CUSA00900) — Extra Quality: Guide & Resources

Method A: Direct FTP replacement (for file-based mods)

1. Enable FTP on PS4 via GoldHEN.
2. Navigate to:
   /user/data/app/CUSA00900/
   (or /mnt/sandbox/pfsmnt/CUSA00900-app0/ depending on payload)
3. Back up any original files you will replace (e.g., eboot.bin, param/*.bnd).
4. Upload modded files preserving folder structure:
   • eboot.bin → overwrite in root
   • param/drawparam.param → into param/
   • map/*.msb → DLC maps
5. Restart the PS4 (or relaunch GoldHEN).

Prerequisites

1. Base Game: Bloodborne v1.00 (CUSA00900).
2. Update File: Official v1.09 PKG (patch).
3. DLC PKG: The Old Hunters (CUSA00900).
4. Tools: GoldHEN 2.3+, FTP client (FileZilla), PS4 PKG Viewer.
5. Mod Payload: Usually a patch.pkg or manual file injection via FTP.

4. How to Apply a Mod (Example for param edits)

1. Dump your game (or download a prepatched pkg – but sharing links is not allowed here).
2. Extract the pkg using tools like pkg2zip on PC.
3. Navigate to CUSA00900/images/sfd/param/ or sfx/param/ (depends on mod).
4. Replace GameParam.parambnd or other .bnd files with modded versions.
5. Rebuild the pkg using Gengp4 + fake_pkg_tools (requires valid keys).
6. Install via debug settings on jailbroken PS4.

Note: This is highly technical and prone to errors.
