EtherMenu Lite | Free & Open Source | PZ B42
═════════════════════════════════════════════ ═══
Hey EPVP,
I've been working on a port of Quzile's EtherHack (originally made for B41) to
the new Build 42 engine. Build 42 is a massive rewrite, the game migrated to
Java 25 bytecode, overhauled the Lua API, rewrote most internal systems and
added proper multiplayer anti-cheat. Porting wasn't a straight copy-paste job.
The result is EtherMenu: a fully working, open source cheat menu for PZ B42
written in Java (API hooks) + Lua (UI). I'm releasing the source publicly so
devs have a working B42 base to build on, the same way Quzile's B41 source
helped the scene back then.

HOW TO BUILD
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
Requirements:
- JDK 17 (Gradle host)
- JDK 25 (compiler — PZ B42 runs Java 25 bytecode)
- Steam copy of PZ Build 42 (42.15.2+)
1. Clone the repo
2. Copy zombie.jar, org.jar, Kahlua.jar, fmod.jar from your PZ install into lib/
3. Run:
.\gradlew.bat jar "-Pjdk25Home=C:\Path\To\jdk-25"
4. Output: build/EtherMenu-1.0.5-lite.jar
5. Drop it in your PZ folder and run: java -jar EtherMenu-1.0.5-lite.jar --install
Uninstall: java -jar EtherMenu-1.0.5-lite.jar --uninstall

NOTES FOR DEVS
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
The B42 port required rewriting most of the Java-side reflection hooks (the
internal PZ class structure changed significantly), fixing all Lua panel calls
to match the new B42 API, and working around the new AntiCheat NPE traps.
The architecture is: Java JAR injects a Lua panel loader at game start →
Lua panels are loaded from resources and rendered via PZ's native ISUIElement
system → Java-side provides the actual game manipulation via the KahluaTable
and zombie.* APIs.
Source is MIT. Fork it, modify it, use it as a base — that's the point.

A NOTE ON THE PAYWALL — READ THIS
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
I'm a hardcore open source believer. Genuinely. This lite version being public
is not a marketing stunt, it's my default position on software.
So why is there a paid full edition at all? Honest answer: my laptop barely works, I'm unemployed, and keeping this maintained has a real cost in
time and hardware. The paywall isn't greed, it's survival. The moment my
situation stabilizes, the full edition goes open source, no conditions, no
exceptions. I'm not building a business here.
On the longevity of this project: I play PZ multiplayer every day. I genuinely
love this game and the community around it. As long as the devs keep shipping
updates without real server-side anticheat, I'll keep updating this, it's a
cat and mouse game I will enjoy playing. And before anyone says it: yes, I want the devs to eventually implement proper anticheat. Good anticheat means a better game for everyone. Until then, things like this will exist.
TL;DR. Temporarily freemium by necessity, permanently open source by
conviction. If you want to support development and speed up the "full open
source" timeline, Discord is linked above.
