Can Open-Weight LLMs Handle Game Decompilation and Recompilation Projects?

A community query on r/LocalLLaMA explores whether open-weight language models can match proprietary AI tools in performing video game decompilation and static recompilation. The post questions whether local models can effectively assist with reverse-engineering retro games on platforms like the Game Boy Advance (GBA) or PlayStation Portable (PSP). Decompilation and static recompilation allow classic video games to be ported as native modern applications rather than relying on emulation. Enabling open-weight, locally hosted LLMs to perform these complex code transformation tasks would make game preservation and porting significantly more accessible. While top-tier proprietary models paired with iterative feedback tools have shown strong progress, open-weight models often struggle with the rigorous accuracy needed to generate matching target C/C++ source code. Platforms with smaller ROM sizes and mature decompilation pipelines, such as the GBA and PSP, are considered the most feasible testing grounds for local LLMs.
