--- Comment #25 from Wylda wylda@volny.cz --- Forgot to mention. After CD3 it truly asks you for CD1 again because of Safedisk protection. Exactly as you predicted, Focht ;) But the protection was removed later anyway:
* Doom3-v1.0.1262.exe - on CD - SafeDisc v3.20.022 * Doom3-v1.0.1282.exe - v1.1 - SafeDisc v3.20.022 * Doom3-v1.2.1287.exe - v1.2 - no safedisk * Doom3-v1.3.1302.exe - v1.3 - no safedisk
