dmg-acid2 is a tool for verifying the emulation accuracy of the Game Boy's Pixel Processing Unit (PPU). Developers can download the ROM or build it using RGBDS to ensure their emulator's output matches a reference image. The test involves various rendering checks, including specific behaviors of the LCDC, background, object priority, and color palettes. It is also designed to highlight common failure cases in emulators, ensuring compatibility with standard Game Boy and Game Boy Color modes.
