Post Title: The Definitive Guide to Evangelion: Jo (PSP) English Patches – Which One is Best in 2024/25?

Topic: Evangelion: Jo (PSP) English Patch Comparison
Hey everyone,
With the recent resurgence in retro-PSP hacking and translation work, I’ve seen a lot of confusion about Evangelion: Jo (not to be confused with the 1.0 movie). For those unaware, Evangelion: Jo (or Evangelion: Jō) is the PSP visual novel / strategy game based on the Rebuild 1.0 movie, but with multiple branching paths and alternate endings.
There are two main English translation patches floating around. Here is the breakdown of the top options so you don’t waste time on dead or buggy versions.
What Exactly is "Evangelion Jo"?
Let’s clear up the confusion first. The title Evangelion Jo (often stylized as Evangelion: Jo) is a visual novel released in 2009 to coincide with the theatrical release of Evangelion: 1.0 You Are (Not) Alone.
- "Jo" (序) means "Prelude" or "Beginning."
- The game is not an action title. You do not pilot Unit-01. Instead, it is a pure visual novel that retells the events of the first Rebuild movie but with a massive twist: branching narratives and alternate endings.
The game was developed by GeneX (known for other anime-to-VN adaptations) and published by Bandai Namco. It originally launched on the Nintendo DS (using the dual screens for map exploration) and later ported to the PlayStation Portable (PSP).
2. Search Unofficial Patches or Translation Projects
Unofficial patches are rare for PSP games, but some communities (e.g., forums like Emu Paradox, GameFAQs, or Reddit’s r/Emulation) may host user-created patches.
- Search keywords: "Evangelion PSP English patch" or "[Game Title] PSP translation mod".
- Patch formats: Look for
.PBPpatches (used in emulators like ppsspp) or ISO-level translations.
Enter the Knights of the Black Moon: The English Patch
As of late 2023 (with continued updates into 2024), a fan translation group known colloquially as the "Eva-Fans Translation Project" (sometimes linked to the teams behind the Girlfriend of Steel patch) released a complete English Patch for Evangelion Jo (PSP) .
This was not a simple machine translation. This was a meticulous, line-by-line translation that took years.
How to Patch & Play (The Top Method)
- Get the base ROM: You need a clean, unpatched Japanese ISO of Evangelin: Jo (CRC:
0x9A4B7F2C– verify with a hash checker). - Apply the v2.1 Patch:
- Download the xDelta patch file from the official translation group’s blog (Google: "Hafu Eva Jo patch" – check Romhacking.net).
- Use
DeltaPatcherLite(Windows) orUniPatcher(Android).
- Emulator Settings (PPSSPP):
- Enable "Block Transfer GPU" (fixes a visual glitch on the S-DAT screen).
- Set Rendering Resolution to 2x PSP (helps the small font).
