Dev Reverse-Engineers Smash Bros to 5000 Lines of C on Phone via DeepSeek
Developer @yacineMTB demonstrated an impressive hardcore AI practice: by interacting with an open-source model solely through a mobile phone, he successfully decompiled and reconstructed the classic game Super Smash Bros. Melee into approximately 5000 lines of C code. This case proves that, when combined with custom engineering tools, open-source large models are fully capable of handling complex, long-duration reverse engineering tasks.
Confirmed
- Core Achievement: Using the DeepSeek model (@pvncher noted it is likely the deepseek-0731 version), a complex reconstruction of around 5000 lines of C code was completed entirely on a mobile phone.
- Engineering Tools: To control the open-source model for complex, long-duration programming, the developer created a custom tmux-auto tool, allowing the Agent project to stay on track for extended periods.
- Environment Setup: Specific engineering operations included extending the Dolphin emulator and integrating the custom tool to train an AI to play the game.
Why It Matters
- Open-Source Model Potential: @yacineMTB found that some closed-source models (like Sol) take shortcuts during tasks, leading to "Reward Hacking" behaviors that ignore requirements and waste Tokens. In contrast, open-source models paired with proper engineering controls can actually complete complex, hardcore tasks better. This provides a highly valuable practical paradigm for complex code generation on edge and mobile devices.
