Defender II is a native C++/VitaGL port of the Android game Defender II for the PlayStation Vita, developed by Rocroverss.

Description

Defender II is a castle defense game in which the player protects their castle from endless waves of enemies using a bow and powerful magic. The player takes the role of the last defender, shooting arrows manually while upgrading strength, speed, and abilities. As the game progresses, enemies become stronger and more challenging, requiring the player to improve their skills and unlock new defenses such as magic towers and special powers.

This port is a ground-up native reimplementation written in C++ using VitaGL. It was developed as an experiment to assess how effectively large language models (LLMs) can reverse engineer closed-source applications and recreate their behavior. AI was primarily used for code analysis and initial implementation, with the final result manually reviewed and refined.

Warning: This port does not ship the full original Android game data. To run the port, users must supply their own legally obtained copy of Defender II for Android (version 1.4.6).

Requirements

• A legal copy of the Defender II Android APK, version 1.4.6
  • Available on the Google Play Store
• Python 3 (to run the included patching tool)

Installation

1. Install the release .vpk from VitaDB or from the project's release package.
2. Obtain a legal copy of the Defender II Android APK, version 1.4.6.
3. Run the patching tool with Python 3:

   python apk_patcher.py

4. Use the tool to prepare the game data from your APK.
5. Install the generated VPK, or copy the patched files into ux0:/app/DDEF00001/.

The expected final file layout on the Vita is:

└── ux0:app/DEEF0001/
                ├── assets/
                ├── sce_sys/
                └── eboot.bin
