AI-Driven Game Memory Modifier: When Large Language Models Meet Game Assistive Tool Development

This article introduces the open-source project GG-AI Modifier, which combines the Flutter cross-platform framework, Kotlin native development, and LLM intelligent dialogue to create an intelligent game memory modification tool with natural language interaction capabilities. The project aims to lower the operational threshold of traditional modifiers and provide a reference case for AI-assisted tool development.

Traditional game memory modifiers (such as GameGuardian) are powerful but have a high operational threshold, requiring users to understand concepts like memory addresses and data types. With the rise of large language models (LLMs), the natural language interaction paradigm provides a possibility to lower the usage threshold, and GG-AI Modifier is an innovative attempt under this trend.

GG-AI Modifier uses a modern tech stack:

• Flutter: As the front-end framework, it supports Android/iOS cross-platform, uses Material Design 3 to provide a dark theme interface, and improves development efficiency.
• Kotlin: Responsible for underlying memory operations, obtains system access capabilities through Root permissions, and core modules include MemoryEngine (memory reading and writing), ProcessManager (process management), etc.
• LLM Integration: The flexible configuration system supports multiple API providers (recommends domestic models like DeepSeek), and is responsible for parsing user intentions to generate operation instructions.

Key highlights of the project's core features:

1. AI Intelligent Dialogue: Supports natural language description of needs (e.g., "Change gold coins to 999999"), has context memory capability, and can handle multi-turn conversations coherently.
2. Real-Time Memory Search: Streaming search displays results while searching, with a speed increase of 3-5 times, supports multiple data types such as byte/word/dword, and intelligently filters system memory areas.
3. Floating Window Interaction: Adapts to horizontal and vertical screens, supports smooth dragging and state synchronization, and includes complete functions (dialogue, search, script library) without switching apps.
4. Script System: Supports Lua scripts, and AI can automatically generate scripts based on user needs (e.g., infinite gold coins script).

Problems encountered during project development and their solutions:

• Floating Window Input Method: Adjusted WindowManager.LayoutParams parameters (added FLAG_ALT_FOCUSABLE_IM and SOFT_INPUT_ADJUST_RESIZE) to achieve normal pop-up and self-adaptation.
• Horizontal Screen Touch Handling: Fixed the coordinate conversion logic in OverlayService.kt to ensure smooth dragging in horizontal and vertical screens.
• Real-Time Search UI Update: Adopted the producer-consumer pattern to balance real-time performance and smoothness, avoiding main thread blocking.

Measures for security and privacy in the project:

• Permission Management: Strictly verifies Root permissions, and error handling and permission checks run through all operations.
• Operation Boundaries: Only operates on the memory of the target application process, avoids modifying key system areas, and stops automatically in case of exceptions.
• Data Protection: Dialogue records are stored locally, API Keys are encrypted and saved, and sensitive information is not uploaded to the server.

Future Planning:

• Short-term: Fuzzy search, search history, bookmarking common addresses;
• Mid-term: AI-generated complex scripts, cloud script library synchronization, automatic game recognition;
• Long-term: Rewrite the search engine in C++, SIMD acceleration, plugin system, remote collaboration.

Summary: GG-AI Modifier is a technical exploration of combining LLMs with traditional tools, providing references for Flutter developers (native integration), AI applicators (scenario combination), and security researchers (memory mechanisms). The project states that it is for learning and research only, reflecting a responsible attitude.
