SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill provides a powerful interface for debugging and testing Sega Saturn games within the Mednafen emulator, streamlining the reverse engineering process.

Core Features & Use Cases

Automated Debugging: Control emulation, set breakpoints, and trace execution via Python scripts.
Memory & Register Inspection: Dump CPU registers and memory contents for detailed analysis.
Use Case: When a game crashes, use this Skill to set a breakpoint just before the suspected crash point, step through the code, and inspect memory to pinpoint the cause of the failure.

Quick Start

Use the mednafen-debugger skill to advance emulation by 10 frames and then pause.

FAQPage Schema

How do I automate debugging for Sega Saturn games in Mednafen?▼

You can automate debugging by using Python orchestrators to control the custom Mednafen emulator fork, enabling scripted emulation advancement, breakpoint management, and memory inspection for Saturn games.

What is instruction-level tracing for reverse engineering emulation?▼

Instruction-level tracing logs executed CPU instructions step-by-step during emulation. This Skill enables tracing within Mednafen to reverse engineer Sega Saturn games by pinpointing exact execution paths and crash causes.

How do I set a breakpoint before a crash in a Sega Saturn emulator?▼

To set a breakpoint before a crash, use the Skill's breakpoint management features to pause emulation at a suspected address. You can then step through code and inspect CPU registers and memory to identify the failure point.

Can I use PowerShell with Mednafen for quick boot testing?▼

Yes, you can use PowerShell for quick boot testing workflows. The Skill integrates with PowerShell to provide distinct testing automation alongside Python orchestrators for rapid emulation cycles.

Does Mednafen support CPU register and memory inspection for Saturn games?▼

Yes, the custom Mednafen emulator fork supports CPU register and memory inspection. The Skill allows you to dump register contents and memory states during emulation to analyze game behavior and debug issues.

What are the limitations of using Mednafen for Sega Saturn reverse engineering?▼

Reverse engineering with this Skill requires a custom Mednafen emulator fork and depends on Python or PowerShell scripting. Users must manually manage breakpoints and memory inspection scripts, as automated tracing does not replace manual code analysis.
