DOSBOX OUTPUT CODE
( MT-32/ CM-32L emulation is included in unofficial enhanced builds, but not in the official source code repository due to need for copyrighted ROM images.) Storage is handled by mapping (either through the configuration file or through a command within the emulator) a drive letter in the emulator to a directory, image file, floppy disk drive, or CDROM drive on the host.
DOSBOX OUTPUT SOFTWARE
MIDI output through an emulated MPU-401 interface is available if the host is equipped with a physical MIDI-Out connector or a suitable software MIDI synthesizer.
DOSBOX OUTPUT PC
Sound hardware that can be emulated includes the PC speaker (played back through the host's standard sound output, not its physical internal PC speaker), AdLib, Gravis Ultrasound, Tandy, Creative Music System/GameBlaster, Sound Blaster 1.x/2.0/Pro/16, and Disney Sound Source.
DOSBOX OUTPUT FULL
Graphics emulation includes text mode, Hercules, CGA (including some composite modes and the 160x100x16 tweaked modes), Tandy, EGA, VGA (including Mode X and other tweaks), VESA, and full S3 Trio 64 emulation. The emulated CPU speed of DOSBox is also manually adjustable by the user to accommodate for the speed of the systems DOS programs were originally written for.ĭOSBox can emulate a wide range of graphics and sound hardware. On systems which provide the i386 instruction set, however, DOSBox can use dynamic instruction translation to accelerate execution several times faster than interpretive CPU emulation. Since DOSBox can emulate its CPU by interpretation, the environment it emulates is completely independent of the host CPU. Other similar programs, such as DOSEMU or VDMs for Windows and OS/2, provide compatibility layers and rely on virtualization capabilities of the 386 family processors.
For similar reasons, no support for long filenames and Ctrl-Break is added into official versions, though support for them is available in some unofficial enhanced SVN builds.ĭOSBox is a full CPU emulator, capable of running DOS programs that require the CPU to be in real mode or protected mode. As an alternative, the PrintScreen function of modern OSs can be used to capture the output of DOSBox. Perhaps the most common hardware feature of DOS-era PCs that the official version of DOSBox doesn't emulate is the parallel port that was used to connect printers. The DOSBox project has a policy of not adding features that aren't used by DOS games if they take significant effort to implement, are likely to be a source of bugs or portability problems, and/or impact performance. In earlier versions, one had to rely on custom modifications and a third-party screen recorder to record video, but the quality and emulator performance was generally very poor. The video recording feature was added in version 0.65. In its uncompressed state the footage is almost an exact replica of the actual program.
DOSBOX OUTPUT ZIP
The video is compressed using the lossless Zip Motion Block Video codec. For ease of use, several graphical front-ends have been developed by the user community.Ī popular feature of DOSBox is its ability to capture screenshots and record gameplay footage.
Forks such as DOSBox SVN Daum and DOSBox SVN-lfn provide additional features, which include support for save states and long filenames (LFN), while others such as DosBox-X add emulation for Japanese systems like the NEC PC-98 and increase compatibility with various Demoscene productions.Ī number of vintage DOS games have been commercially re-released to run on modern operating systems by encapsulating them inside DOSBox.ĭOSBox is a command-line program, configured either by a set of command-line arguments or by editing a plain text configuration file. But throughout these years development has been ongoing in the SVN version. More than 8 years have passed between 2010's 0.74 and the 2018's latest version 0.74-2, "a maintenance release" made in preparation "for the upcoming 0.75 release, which will enter regression testing soon". The added features include virtual hard drives, peer-to-peer networking, screen capture and screencasting from the emulated screen. DOSBox has been downloaded over 34 million times since its release on SourceForge in 2002.Ī number of usability enhancements have been added to DOSBox beyond emulating DOS.
