FCEUX11 Files

Every supported NES/Famicom cartridge board now runs through a unified fceu11::Mapper subclass with auto-registration, replacing the legacy C-style function-pointer dispatch. Together with the v1.7 Cart class and v1.6 APU objectification, the entire core is now modern C++ — games load more predictably and the codebase is dramatically easier to maintain. 所有 174 款受支持的 NES/Famicom 卡带 mapper 现在统一通过 fceu11::Mapper 子类（含自动注册）运行，取代旧的 C 风格函数指针调度。结合 v1.7 的 Cart 类与 v1.6 的 APU 面向对象化，整个核心已全部现代化——游戏加载更可靠，代码库更易维护。

Twenty-three different MMC3-family mappers — the family behind Super Mario Bros 3, Kirby's Adventure, Mega Man 4–6, and hundreds more — now inherit from a single Mmc3BaseCart base class. Behavior stays consistent across the whole family and a single fix applies everywhere at once. MMC3 系列 23 款不同 mapper（涵盖超级马里奥兄弟 3、星之卡比、洛克人 4–6 等数百款经典）现在统一继承自 Mmc3BaseCart 基类。整个家族行为一致性显著提升，一次修复全家族受益。

VRC7, MMC5, Namco 106 and Sunsoft 5B expansion-audio chips now use the same ExpansionAudio virtual interface introduced for VRC6 in v1.6. The audio path is cleaner, more predictable, and easier to extend when new chips are supported. VRC7、MMC5、Namco 106 与 Sunsoft 5B 等扩展音频芯片现在使用与 v1.6 VRC6 相同的 ExpansionAudio 虚拟接口。音频路径更清晰、更可预测、更易扩展，未来加入新芯片更省力。
