  "description_en": "This recreates the source of Tube, the 1994 DOS game from Bullfrog, using Hex-Rays and IDA Pro. The result builds as a 32-bit program with SDL2. Windows uses build_windows.bat, Linux uses build_linux.sh, and the web build uses build_web.bat. The README also lists OpenWatcom 1.9 for a DOS DPMI build. It says the original code uses 32-bit pointers, so this tree does not build as 64-bit.",
  "description_zh": "该项目用 Hex-Rays 和 IDA Pro 重建 Bullfrog 1994 年 DOS 游戏 Tube 的源码。结果用 SDL2 做成 32 位程序。Windows 用 build_windows.bat，Linux 用 build_linux.sh，网页构建用 build_web.bat。README 还列出 OpenWatcom 1.9 用于 DOS DPMI 构建。它写明原始代码使用 32 位指针，所以这棵源码树不能编成 64 位。",
