  "description_en": "Portal 2 is statically recompiled from its Linux x86 modules into a native ARM64 application for macOS and iPhone. Preparation tools lay out ELF modules and apply relocations; a lifter emits C functions that are compiled with a runtime for libc, threading, SDL2, graphics and Steam interfaces. The author reports playable builds on Mac and iPhone.",
  "description_zh": "该项目把 Portal 2 的 Linux x86 模块静态重编译为适用于 macOS 和 iPhone 的 ARM64 应用。准备工具处理 ELF 模块布局与重定位，提升器将函数转换为 C，再与实现 libc、线程、SDL2、图形和 Steam 接口的运行时一起编译。作者报告 Mac 和 iPhone 版本可游玩。",
