Sega Saturn
Game Patches

Our current release is a Korean localization patching tool for Sega Saturn games. Players are already using our released Korean patches; future work will explore loading times and performance improvements.

Research direction

02 / RESEARCH

Reverse engineering. Measure, then improve.

Planned work

Loading & performance

Investigate loading paths and runtime bottlenecks in existing Sega Saturn games. Compare baseline and patched behavior before claiming an improvement.

Parallel architecture

Study the Saturn’s parallel processing design and test where its architectural ideas remain useful in today’s computing context. This is an open research question, not an established result.

Community feedback

Existing players are using the Korean patches. Bug reports and feedback can guide further work; broader demand and a commercial model have not yet been established.

About Dapsimni AI

Dapsimni AI is a self-funded sole proprietorship founded by Donghee Na in December 2025 and registered with South Korea’s National Tax Service. Our released browser patcher and public GitHub repository provide working software and reproducible validation records. We have no external investment. A broader commercial model is still being evaluated.

How we build with Claude

03 / DEVELOPMENT

From shipped patches to repeatable workflows

Claude supports code writing, translation, binary analysis, reverse-engineering design, automated tests, patch releases and website deployment. The founder uses Claude Max 20x today. Planned API work will prototype localization consistency checks, code-analysis reports and regression-test generation, with human review and deterministic validation.
