Neue DosBox-Version

[Crystal]

Danke für die Info!

32bit-Prozessoren werden besser unterstützt. Neu ist die Unterstützung für 64bit-Prozessoren wie z.B. der Athlon 64.

Es wurden Hänger beseitigt, die nach langer Spielzeit von diversen Spielen auf einigen Betriebssystemen auftreten konnten.

Einige Bugs bei der Joystick-Unterstützung entfernt.

Verbesserte CDRom-Unterstützung bezüglich Audiotracks, ISO-Images und deren Erkennung.

Der SVGA- und VESA-Bildschirmmodus wurde verbessert (Erkennung und Anzeige)

Ein paar Textmodi sowie die ANSI-Emulation (bezüglich Datenfernübertragung) wurden korrigiert.

Der PCSpeaker und einige Soundeffekte korrigiert. Wahrscheinlich eine bessere Unterstützung der Soundkarten allgemein.

Mounting von echten Laufwerken sowie das Mounting von Images wird standardmäßig mit aktiviertem Input/Output-Controller gesetzt. Wichtig für Win2000/XP/Vista-User. Unterstützung der Tilde (~) sowie automatische Größenerkennung für Images eingebaut.

Wofür der Mousebackdoor gut sein soll, weiß ich nicht.

Der Programmcode wurde gegenüber der alten V0.70 optimiert.

Einige kleinere Fehler korrigiert, die die Kompatibilität erhöhen (betreff Spiele z.B.)


Aus meiner Sicht ist die neue Version 0.71 nur für Leute interessant, die 64bit-Prozessoren haben und vorwiegend mit CD-Images spielen. Generell sollte man umsteigen, denn die verbesserte Unterstützung für 32bit-CPU's bringt eventuell ein flüssigeres Gameplay (siehe Schweif und Riva) mit.
Was den korrigierten SVGA-Modus angeht, kann es sein, dass er den schwarzen Balken unter der Heldengruppe verschwinden lässt. Muss man ausprobieren...

Die neue Version läuft bei mir mit dboxfe unter Linux bei Riva stabil und subjektiv auch ein bisschen schneller. Keine Ahnung ob es auch wirklich schneller läuft.

Eine weitere Bugfixversion von DOSBox wurde veröffentlicht.

DOSBox 0.72 has been released!

This release fixes a few bugs that slipped through when releasing 0.71.
Here a list of the changes:

* Fixed unitialized variable in joystick. (Fixes crashes on Vista and Mac OS X)

* Some bugfixes and speedups to the 64 bit recompiling core.

* Fixed sign flag on soundblaster dma transfers (Space Quest 6 intro)

* Fixed a bug in keyboard layout processing code and fixed certain layouts.

* Fixed Dreamweb.

* Improved speed unlocking when running cycles=max.

* Fixed a crash related to the tab completion in the shell.

* Improved aspect correction code. Should now be like how a real monitor handles it.

* Fixed a bug in the xms status report code. (Blake Stone 1.0 shareware)

* Added a lot more keyboard layouts.

* Fixed crash related to changing the scaler before a screen was created.

* Hopefully fixed compilation on *bsd.

* Enabled auto cpu core selection for recompiling core as well.

* Made the used joystick selectable when 4axis is specified.

* Added some hints for inexperienced DOS users to the shell.


Compatibility should be same as 0.71 and 0.70 aside from the game specific fixes.

Hui, DOSBox 0.73 ist da.

[Obi-Wahn]

Danke für die Info!

bei der neuen Dosbox stört mich nur eines:

Im Vollbildmodus funktioniert die "Aspect correction" bei mir nicht mehr!
Mit der Version 0.72 funktioniert es aber einwandfrei.
bei der 0.73 funktioniert die "Aspect correction" nur auf dem "Windows Desktop"

Schon komisch, da ich bei der 0.73 die gleichen Einstellungen vornehme wie bei der 0.72
z.B. Output=ddraw, scaler=normal3x...
Auch die Änderungen bei Output=surface, opengl etc etc; fulldouble=true; Machine=vesa_nolfb bringen nix

Hab WinXP Pro, ne ATI X1950...

Hab zwar keine genaue Ahnung was "Aspect correction" genau ist, aber bei der Version 0.72 ist die Vollbild-Darstellung von z.B. Riva wie bei einer 4:3 Sendung auf einem 16:9 Fernseher.
Links und rechts sind schwarze Balken und das Seitenverhältnis/Proportionen sind stimmig.

Eine perfekte Pillarbox-Darstellung eben...

Beim DOSBox-Team tut sich nach langer Zeit wieder was. Neue Version heute erschienen + Ankündigung der Version 0.75
-> https://www.dosbox.com

DOSBox 0.74-2 has been released!

A maintenance release for DOSBox 0.74, which solves the following problems:

• Windows: Fix auto/max cycles algorithm on Windows 7, which helps with stuttering audio.
  
• Mac OS X: Bring a 64 bit version and improve performance.
  
• Linux: Fix the 64bit dynrec cpu core and a lot of compilation problems. Add patches for the WINE Team.
  

The game compatibility should be identical to 0.74.

We have saved all game fixes for the upcoming 0.75 release, which will enter regression testing soon. This release has been created so you can go back to 0.74-2, in case we happen to break your favourite game in 0.75.

DOSBox 0.75 ist leider noch nicht da, dazwischen wird noch ein Bugfix-Release in Version 0.74-3 nachgeschoben:

DOSBox 0.74-3 has been released!

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.
  

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


Ideally, 0.75 should have been released by now, but some bugs took a lot longer than expected.
