Unlock the full potential of your CHIP-8, SUPER-CHIP, or XO-CHIP interpreter with our meticulously crafted collection of ROM test images. These resources provide vital insight into emulator behavior, helping you diagnose and refine your code. Whether you're a novice or a seasoned developer, our open-source project supports your coding journey with clarity and collaboration.
The CHIP-8 Test Suite is an essential resource for developers aiming to create their own CHIP-8, SUPER-CHIP, or XO-CHIP interpreters or emulators. This project provides a comprehensive collection of ROM images that serve as tests to validate the functionality of your interpreter.
Overview
Finding reliable documentation regarding the expected behaviors of the CHIP-8 variants can be quite challenging. This test suite addresses this issue by providing developers with a standardized way to test their implementations against well-defined benchmarks.
What You Will Find
The test suite includes the following tests:
- CHIP-8 Splash Screen: Verify your implementation with a simple display operation.
- IBM Logo: A classic ROM to check basic drawing capabilities.
- Corax+ Opcode Test: A thorough assessment of various opcode functionalities, designed to reveal any issues in your interpreter's logic.
- Flags Test: Evaluate the accuracy of your mathematical operations and their effect on the flag register.
- Quirks Test: Identify subtle behavior differences that may affect game compatibility across platforms.
- Keypad Test: Test all key input opcodes for accurate interaction.
- Beep Test: Ensure sound functionalities are operational through Morse code signaling.
- Scrolling Test: Examine scrolling capabilities for advanced CHIP-8 interpreters.
How It Works
Each test consists of a ROM that executes specific operations, validating the underlying implementation of your interpreter. This allows developers to capture detailed insights into discrepancies or bugs within their systems. The tests are designed to run uniformly across all three primary CHIP-8 platforms — CHIP-8, SUPER-CHIP, and XO-CHIP — with the quirks test intended to highlight platform-specific behavior.
Community and Contribution
Engagement from the community is highly encouraged. If you identify any issues or have suggestions for additional tests, contributions are welcome. Detailed instructions on how to build the project and integrate any changes are provided within the repository.
