Thema: DOSBox : Alte Spiele und Programme wieder nutzen ...

[SiLæncer]

vDos is derived from the DOSBox project, it allows you to conveniently run DOS programs in Windows.

DOSBox is targeted at gaming and available for many operating systems.

vDos is for serious (mainly text mode) DOS applications, Windows 32/64 bits (XP and later) only.
It lacks many of the hardware emulations of DOSBox (no joysticks, basic VGA...). Instead it adds a live file system, file/record locking, Windows printing, a scalable screen font and more.

You should be able to run your DOS application quickly in a safe and convenient way.

Changelog

•Switched to 3 distinct CPU mode emulators with a speed gain of 5 to 30%. Special DataPerfect (DP2.6Y) support will let it run nearly as fast as in NTVDM (same hardware), and comes with network optimization.
•DOS compatibility fixes like a system wide uniform BIOS/DOS date/time. Line endings in text files. DIR command counting directories as files. Create temporary file API not creating an actually random file(name), and worse, overwriting it if present.
•Some improvements to FPU emulation and printing.
•Long awaited fix of the occasionally (and illusive) Page Fault errors with FoxProX.
•Copy/paste in full screen.
•vDos is further silenced, a beep.wav file has to be supplied in the vDos directory to define the system beep.
•Idle detection scheme overhauled. The previous one especially let vDos go idle premature with file operations. vDos still attends to the DOS program in idle mode, though at a far lower rate. But will go to hibernate after 5 minutes of continuous idle time. So vDos CPU usage should drop to zero, even on lesser hardware.
•If ASCII 0-31 characters were redefined in a codepage, the lower/original ones were still used.
•Support of key stuffers like AutoHotKey: Handling extended characters and BIOS keyboard buffer overflow.
•Some programs on exit set the VGA registries directly, this could mislead vDos the window was resized.

Changelog

This is a security release for DOSBox 0.74:

    Fixed that a very long line inside a bat file would overflow the parsing buffer (CVE-2019-7165 by Alexandre Bartel)
    Added a basic permission system so that a program running inside DOSBox can't access the contents of /proc (e.g. /proc/self/mem) when / or /proc were (to be) mounted (CVE-2019-12594 by Alexandre Bartel)
    Several other fixes for out of bounds access and buffer overflows.
    Some fixes to the OpenGL rendering.

It's recommended to use config -securemode when dealing with untrusted files.
The game compatibility should be identical to 0.74 and 0.74-2.

Changelog

Machine code routines converted to C/C++, vDos is potentially CPU type (not Windows) independent. Loss of performance of the emulated CPU is limited to a few percent by squeezing out the last possible optimizations.

There’s now also a 64-bit edition (vDos64), however not publicly available/advertised. That would mostly just be confusing: "I need that version since I have Windows 64-bit". vDos64 has a larger footprint and is slightly slower than its 32-bit counterpart, that runs in both Windows 32- and 64-bit.

Unused FreeType options/extensions removed, some common code of the 3 CPU emulators merged, rarely used code compiled for size. vDos.exe lost weight, despite added functionality.

Added KEYCODE= option, setting the reported scan and ASCII code of a specific key.
Alt+Space opens the vDos system menu, Win+Dn minimizes, Win+Up restores the window.
Ctrl+Mousewheel changes the font/window size. As with Windows CMD, the top left corner is fixed.

The Windows command line processor (CMD) needs the current work directory set to a drive letter. With network/mapped Windows drive letters, this gave a problem since vDos always used the UNC paths.
Removed stripping double quotes from the command line to better support calling Windows CMD.
vDos will refuse to run if started elevated. There should be no need for that.

The eventual nag couldn’t be clicked away if vDos was minimized.
As vDos went to 'Hibernate', it could become unresponsive.

FreeType library updated to version 2.10.1.
Internal TTF font character positions vertically raised so they center better within the cells. Some other refinements to individual characters.
Line drawing characters of the internal font set to single points (more discreet lines) at all resolutions.
Added EXTEND= option to mask/hide on-screen text, like a silly (or even annoying ticking) clock.
COLORS= dropped in favor of the more convenient THEME=<number> (0-9). System menu item added to cycle thru the themes (preview, if not explicitly set).
Default color of the DOS text cursor changed.

Internal printing is handled by a separate thread to facilitate some HP drivers and Microsoft virtual printing.
Added timeout options to optimize faster printer response. Added PRIVATE option to skip creating print files.
Some improvements to the PCL printer code parser.

'Turbo' text pasting reinstated. It was once disabled to overcome a Clipper bug. Now pasting in other programs should again be as fast as those can process input.

Added BTRIEVE= option to connect to a Windows Pervasive/BTR2SQL interface. Mind, this extension/functionality doubles the vDos license fee.

Fixed FPU rounding errors in specific situations. Added support of some obscure FPU instructions.

Some (built-in) ANSI.SYS refinements.

Changelog

    vDos.exe is once more smaller (for if you would question that). Some 15% CPU overall speed gain, though FoxProX code will run up to 50% faster. Priority of vDos.exe set to “High” to give it a slight advantage when competing with other programs for CPU attention.
    Detection of extensive keyboard polling by a DOS program: vDos will then drop to idle mode sooner.
    Print processor passes on eventually set copies option and the like to the print driver.
    Text is transferred as strings instead of individual characters, resulting in smaller Windows print jobs and PDF's.
    Added a bold variant of the internal font (can also be used for display).
    Changed the DOS DTA based find file API to Windows search handles conversion strategy.
    Switched from Windows GetBinaryType() API to examining the header bytes to determine a file type.
    Screen DPI awareness: vDos renders text at the (higher) native resolution if Windows is set to scale content.
    Added a simulated dark mode of the DOS screen (probably a gimmick?).
    Changed WINDOW= to size%[,horz%:vert%] for more consistency and uniform positioning. “Set as default” system menu option added when the window is resized, saving the window size and position to config.txt.
    Some refinements to command line parsing. Redirecting output was 'sticky', it stayed active.
    Redirection of Windows CMD or START command are no longer trapped by vDos command line processor.
    Forced pasting text in programs that bypass INT 16.
    Extended functionality for select/copy text. See the last paragraph of Printing.pdf for details.
    Faulty EXEPACKed DOS programs will load/start correctly w/o external help or sacrificing the first 64KB memory block.

DBGL serves as a frontend / Graphical User Interface to DOSBox. It tries to make creating DOSBox configuration files a little easier by offering a relatively simple interface, some shortcuts and a little bit of intelligence. Once your DOS games are configured in DBGL, its very easy to setup or start them, or alter their configuration or associated DOSBox version.

Freeware
