SYSTEM DOCUMENTATION & REQUIREMENTS

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

What problem does it solve?

This Skill automates the process of verifying that a game disc image boots correctly to its main menu or attract mode, ensuring the integrity of your game files and builds.

Core Features & Use Cases

  • Automated Boot Testing: Launches the game emulator and checks if it reaches the expected visual state.
  • Golden Baseline Comparison: Compares screenshots against a pre-defined correct image to detect regressions.
  • Use Case: After rebuilding a game binary or modifying a disc image, use this Skill to quickly confirm that the game launches and displays the attract mode as expected, preventing wasted time on non-bootable builds.

Quick Start

Run the screenshot test for the default disc image.

Frequently Asked Questions about screenshot-test

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I automate game boot testing with screenshots?▼

Automated screenshot boot testing launches the Mednafen emulator, waits for the attract mode, and compares the resulting screenshot against a golden baseline image to verify correct disc image booting.

What is golden baseline image comparison for emulator validation?▼

Golden baseline image comparison validates emulator boot states by capturing a screenshot after launch and checking it against a pre-defined correct image to detect visual regressions or corrupted game builds.

How do I verify a rebuilt game binary launches correctly?▼

To verify a rebuilt game binary launches correctly, run an automated boot test that launches the emulator and confirms the game reaches the expected attract mode visual state.

Does this screenshot boot test work with Mednafen?▼

Yes, the screenshot boot test works with Mednafen by automatically launching the emulator, waiting for the game to reach attract mode, and capturing the screen for validation.

Why use screenshot comparison for game development validation?▼

Screenshot comparison is used for game development validation to quickly confirm that modified disc images or rebuilt binaries launch correctly and display the expected attract mode, preventing wasted time on non-bootable builds.

What are the limitations of automated screenshot boot testing?▼

A limitation of automated screenshot boot testing is that it primarily verifies if the game reaches the expected visual attract mode state, meaning it may not detect runtime errors or audio issues that occur after the initial boot screen.
