Installing the patch
The patcher is still a work in progress. The current focus is mapping out where everything lives in the game's data so the translation is easier to polish later, not shipping a finished, widely-tested build yet. No specific CFW/Luma3DS version has been confirmed as tested. Treat everything below as "how the tool works today," not a guarantee it's ready for a general audience.
1. Prep
New Love Plus+ is a Japan-exclusive 3DS title: it never had an official Western release, so you'll need your own dump of the JP cartridge or eShop copy (Title ID 00040000000F4E00). The dump must be decrypted and match one of a fixed set of known-good hashes, checked automatically before anything else happens:
- A decrypted
.ciadump, or - A decrypted
.3ds/.ccicartridge dump
If your dump doesn't match one of the accepted hashes, the patcher will refuse it rather than risk patching something it can't verify. That's by design, not a bug.
The accepted decrypted-dump SHA-1 hashes (the EngPatcher README is the canonical list; check there if this page is stale):
811d2f0f72c2a1437997256f30b18fbb2dea6cda(decrypted.cia)6af1751f8b4f9d074311f3a7cf2b5d3c5e807cc8d138d92fd9d522827cb9665bc2c954f1e8ba1f92(decrypted full.3ds)
Encrypted dumps are no longer accepted: decrypt yours first (a batch CIA/3DS decryptor does this). Many other decrypted CIAs will still fail the check by design. You can pass --expect-sha1 <hash> to require one specific dump; --skip-hash bypasses the check and isn't recommended.
Back up your save before installing anything. Use Checkpoint or FBI's own save-export option to copy your New Love Plus+ save off the console/SD card first. The patch only touches the game's ROM (RomFS/ExeFS), not save data, so your save carries over. Back it up anyway in case something goes wrong during install. Don't skip the backup.
You'll also need:
- A Windows x64 PC (the patcher itself only runs on Windows)
- Python 3.10+ on your PATH
- A few GB of free disk space (the RomFS rebuild is large)
2. Patch
Get the patcher from the EngPatcher repo (see its README for the full setup). Once you have it:
- Double-click
Drop CIA or 3DS Here to Patch.bat. - Drop your
.cia,.3ds, or.ccidump onto the window (or use Browse → Patch). - Wait. If a prebuilt English UI bake is available, patching usually finishes in a few minutes. If not, the tool falls back to rebuilding it from source assets first, which can take on the order of 16 hours on a first run. This only needs to happen once per machine, and progress lines mean it's still working, not stuck.
3. Verify
The patcher writes its output CIA to out/NewLovePlusPlus-EN.cia. From there:
- FBI (CFW, real hardware): copy the CIA to your SD card and install it with FBI.
- Azahar / Citra (emulator): open the CIA directly, or use the LayeredFS output under
out/luma/in the emulator'sload/mods/folder. - Luma3DS LayeredFS (CFW, no reinstall): copy
out/luma/00040000000F4E00/toSD:/luma/titles/and enable "Enable game patching" in Luma's Rosalina menu.
Boot the game and confirm menus and dialogue are showing in English.
Known issue: installing the patched CIA over the network with Boop doesn't work. Copy it to the SD card and install with FBI instead, or open it directly in Azahar/Citra.
