The original PSP game contains strict anti-piracy features that detect custom firmware. Modifying the ISO for translation often triggers these checks, requiring skilled hackers to remove them.

Weapon names, upgrade menus, NERV base management screens, and battle tutorials are completely localized.

The push for Evangelion Jo is part of a larger 2025–2026 resurgence in fan-led localization efforts.

To apply the patch:

The fan translation effort is currently stalled at a critical point: . While the fan translators have succeeded in extracting the contents, translating the text, and even reinserting it into the extracted folder, they have yet to find a way to rebuild the edited files back into the NEVA.PKG archive. Without this final step, the PlayStation Portable (or its emulator, PPSSPP) cannot read the translated data, rendering the patch non-functional.

Unlike traditional mecha games, combat uses a command-based system where players select attacks (knives, rifles, or melee) that trigger high-quality 3D cinematics.

Without a custom script to unpack and repack the NEVA.PKG file, translators cannot extract the dialogue scripts, menu fonts, or user interface textures. Text Hacking & Font Constraints

The latest revision tracks have systematically translated the story segments. Because the game utilizes a mix of visual novel text boxes and fully voiced cutscenes, translators have inserted English subtitles directly into the dialogue boxes.

A PC or mobile utility tool like xDelta UI (for Windows/Mac) or PPF-O-Matic to inject the translation into the original game file.
