FastIntelligence has re-released its iDOS virtual DOS application onto the App Store in the form of an update. Originally released last November, the original version of iDOS was a DOS emulator for iOS devices that allowed users to run old PC DOS based applications ranging from Doom to Windows 3.1 on an iOS device. Applications were loaded onto the device over USB using the iTunes File Sharing feature and a simple DOS prompt and virtual keyboard was provided to extract and run DOS commands and applications transferred to the device. The application was removed from the App Store after only a day, presumably for violation of Apple’s App Store policies against running external code in iOS applications.
Late last night iDOS 2.0.1 appeared as an update for owners of the previous version with the significant change that the iTunes File Sharing feature has been removed, preventing users from installing their own external code. Instead, the package includes a number of DOS freeware/shareware games from 3D Realms including Wolfenstein 3D, Major Striker, Duke Nukem I and II, SuperNova and Kingdom of Kroz II. The update also adds a simplified game launcher so users are not required to use the DOS command-line and a virtual gamepad/joystick within the app. Improvements have also been made to landscape view and Bluetooth keyboard support for text-based games has been added. iDOS 2.0.1 is available from the App Store as a free download. Users of iDOS 1.0 may wish to back up their existing version before downloading the update.
