  "description_en": "Elite: Harmless is a full ca65 disassembly of the Commodore 64 release of Elite, taken from the 1986 GMA86 disk, with the code split into flight, docked, text, ship-hull, math, sound and graphics modules. Its build script reassembles the original loader stages and game files, checks them against MD5 sums, and writes a disk image. The same source builds an enhanced variant with a faster multiplication routine and faster line drawing, and a loader document explains the choice of the GMA86 disk and describes the first stage of its copy-protected loader.",
  "description_zh": "Elite: Harmless 是 Commodore 64 版 Elite 的完整 ca65 反汇编，底本为 1986 年的 GMA86 磁盘版，代码按飞行、停靠、文本、飞船模型、数学、声音和图形等模块拆分。构建脚本会重新汇编原版加载器各阶段和游戏文件，按 MD5 校验后生成磁盘镜像。同一套源码还能构建增强版，采用更快的乘法例程和画线代码；另有加载器文档说明选用 GMA86 磁盘版的原因，并解析带拷贝保护的加载器的第一阶段。",
