A test ROM for Game Boy (DMG) emulator developers to verify accurate PPU emulation.
What is dmg-acid2?
dmg-acid2 is a test ROM for Game Boy (DMG) emulator developers to verify the accuracy of their Pixel Processing Unit (PPU) emulation. It provides a visual reference image that an accurate emulator must reproduce, testing various graphics rendering features like object priority, tile mapping, and PPU flag handling. The project helps ensure emulators correctly implement the Game Boy's graphics hardware specifications.
Developers building or maintaining Game Boy (DMG) emulators who need to validate the accuracy of their PPU implementation. It is also useful for retro gaming enthusiasts interested in emulator development and hardware accuracy testing.
Developers choose dmg-acid2 because it offers a standardized, visual compliance test specifically for Game Boy PPU emulation, with clear failure examples that diagnose specific inaccuracies. It is designed to be accessible, working with simple line-based renderers without requiring cycle-accurate timing, making it a practical tool for improving emulator quality.
