Summary by CodeRabbit

  • Bug Fixes

    • Improved interrupt handling to prioritize and service the highest priority interrupt when multiple interrupts occur simultaneously.
    • Enhanced PPU timing to allow multiple mode transitions within a single update, ensuring accurate scanline and mode updates.

  • New Features

    • Added support for HBlank DMA transfer.

  • Tests

    • Added tests to verify interrupt prioritization and PPU behavior with large cycle counts.
