A collection of ROM images for testing CHIP-8, SUPER-CHIP, and XO-CHIP interpreters during development.
CHIP-8 test suite is a collection of ROM images that provide comprehensive testing for developers building CHIP-8, SUPER-CHIP, or XO-CHIP interpreters. It solves the problem of inconsistent documentation and platform quirks by offering validated tests that verify opcode implementation, input handling, display behavior, and sound output. The suite helps ensure interpreters behave correctly across different historical versions of the CHIP-8 platform.
Developers and hobbyists building CHIP-8 interpreters or emulators, particularly those who need to verify correctness across CHIP-8, SUPER-CHIP, and XO-CHIP variations.
It provides a community-validated, comprehensive testing solution that addresses the subtle differences between CHIP-8 platforms, reducing debugging time and increasing emulation accuracy. Unlike fragmented resources, it offers a unified test suite with clear visual feedback and version tracking.

Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Tests all major opcodes from clear screen to BCD conversion, as detailed in the Corax+ and flags tests, ensuring thorough validation of interpreter logic.
Includes a dedicated quirks test that identifies behaviors specific to CHIP-8, SUPER-CHIP, and XO-CHIP, such as vF reset and shifting quirks, helping avoid subtle bugs.
Validated against real hardware like HP48 calculators and established emulators like Emma O2 and Octo, as noted in the baseline section, ensuring reliable test results.
Each test provides visual indicators like checkmarks and crosses with version numbers, as shown in screenshots, making debugging straightforward and shareable.
Requires a pre-existing CHIP-8 interpreter to run the ROMs, which can be a hurdle if the interpreter itself is buggy or not yet functional.
Some tests, like the keypad and quirks menus, require user interaction, making automated testing more complex without additional setup like memory address overrides.
Only supports CHIP-8, SUPER-CHIP, and XO-CHIP, excluding other historical variants or modern extensions, which might not cover all emulation projects.
