DOSBox Pure 1.0 Preview 1
This is the first preview release of version 1.0 of DOSBox Pure.
A year has passed since the last release 0.9.9 and over 200 changes big and small have been implemented. Thank you for waiting and please test this release and provide feedback as we work towards a release we can call 1.0. Feedback is welcome here as well as on Discord.
Main New Features
Add OpenGL renderer for 3dfx Voodoo (273144a) (#519)
This feature brings a massive performance jump for emulating the 3dfx Voodoo card across all platforms where RetroArch supports OpenGL, which of course includes mobile platforms. While performance can be two to five times faster, the image can also be scaled up to higher resolutions (2x up to 8x). Here are two videos made by @PoloniumRain to show off how well it looks and runs:
 |
 |
|---|---|
| 3dfx Voodoo with OpenGL on Android | Forsaken in 4K |
Besides the OpenGL rendering, the 3dfx Voodoo emulation has gotten various improvements and bug fixes like gamma correction (controlled by a core option) and switching the default chip setup to a 8MB RAM model which has much better compatibility with Windows 95/98 games. Unreal engine based games like Deus Ex and Diablo 2 for example now both run correctly with the 3dfx renderer.
Action Wheel (#477)
The action wheel feature opens a radial menu while holding a button. An action can then be selected via analog stick or mouse movement after which the wheel closes again. This is similar to a "weapon wheel" in many modern action games played with a gamepad.
Auto Skipping Text Console
Commit b9d0b23 introduced skipping ahead to the next video mode change when using the auto start feature. This means pressing RIGHT twice while in the start menu will enable "Skip showing the text console" while continued pressing RIGHT will activate skipping a number of frames. Many DOS games like DOOM will show some startup procedure in the text console which can now easily be automatically skipped by setting "Skip showing the text console", no need to figure out exactly how many frames it takes.
Shift Gamepad Mapping While Holding a Button
The issue #521 caused implementation of a new "Port #X While Holding" action that can be mapped to a button on the gamepad. While such a button is held down, the entire mapping of the gamepad is shifted to act like Port #X. Therefore multiple sets of inputs can be made accessible to a single gamepad.
Enhanced Aspect Ratio Correction Options
Throughout issue #512, various enhancements to the Aspect Ratio Correction core option were implemented. The available options are now as follows:
| Setting | Description |
|---|---|
| Off | Pixels are drawn as square pixels |
| On (single-scan) | Aspect ratio is performed entirely by the frontend |
| On (double-scan when applicable) | On certain DOS video modes, depending on the graphics emulation, lines or columns will be doubled by the emulation. This can improve the accuracy of things like CRT shaders or output to a real CRT monitor. |
| Padded to 4:3 (single-scan) | Add borders to force the output to be 4:3 (to output to a real CRT monitor or switching full screen to an abnormal resolution) |
| Padded to 4:3 (double-scan when applicable) | Force 4:3 and also perform line or column doubling |

Credits
Huge thanks to the maintainers of DOSBox and the various forks that are out there. For this release in particular I'd like to thank
Taewong who started the DOSBox SVN Daum branch a long time ago and Jonathan Campbell who heads the DOSBox-X project, which continues its mission of increasing capabilities and compatibility of DOSBox. Also thanks goes to kekko who created the DOSBox integration of the 3dfx voodoo emulation, based on the work of the SST-1/2 emulator by Aaron Giles from the MAME team.
Installing and Booting an Operating System
When loading content with a bootable CD-ROM image or both a CD-ROM image and a bootable floppy disk image, a new option [ Boot and Install New Operating System ] will be available in the start menu. After using that option to create a hard disk image and installing an operating system, any loaded content (i.e. ZIP files or CD images) can be loaded into that operating system. See the documentation of the feature for more details.
Issue link for feedback on this feature: #105
3dfx Voodoo Emulation
Supports both compatible DOS games as well as running 3dfx and Direct3D games in Windows 95/98. For details and how to setup drivers in Windows see the documentation of the feature for more details.

DOSBox Pure 0.9.2
This is the third beta release of DOSBox Pure.
Changes in 0.9.2:
- Add a core option to control dosbox.conf loading (#262)
- Option to load .conf files outside the loaded ZIP or folder (#257)
- Fix running certain versions of Lemmings with all core options on default (#259)
- Filter our invalid characters in file/directory names of mounted ZIP files (#255)
- Disallow removing of non-empty directories
- Scale on-screen-keyboard nicer in games that use odd monitor resolutions
- Show in controls menu of frontend when gamepad mapper overrides are in use
- Improve performance of startup and restart
The recent version 0.9.0 was a big update with improvements and new features, thus the switch to the new version numbering and beta tag.
Gamepad Mapper
If you need even more customization of the controls than provided by the Automated controller mappings, or the various presets for mouse, keyboard and joysticks you can use the new gamepad mapper.
To open it, click the "PAD MAPPER" button in the On-screen keyboard
It is available any time in-game and changes are immediately saved and applied when closing the mapper. Up to 4 functions can be mapped for any button/direction of the gamepad. A mapping can be to any function of the 3 emulated input devices: keyboard, mouse or joystick.
Issue link for feedback: #57
Directly run PC booter games from the start menu
This also adds support for swapping floppy disk images (or PCjr cartridges) at runtime via a frontend's Disc Control menu and hotkeys.
Issue link for feedback: #102
Support loading of dosbox.conf files
DOSBox Pure can boot directly from a .conf file or it will load C:\DOSBOX.CONF automatically if it exists in the mounted ZIP or path.
Issue link for feedback: #209
Don't enter solo root directory when mounting ZIP files
When mounting a ZIP file which has just a single directory in its root, the core used to mount that directory as the C: drive. Now the core will mount the root of the ZIP to improve compatibility with DOS games that need to be installed in a specific location on the hard drive. The old behavior will still be used if an old save file (named GAME.save.zip) exists. The new behavior uses a differently named save file (GAME.pure.zip).
Issue link for feedback: #87
DOSBox Pure 0.9.1
This is the second beta release of DOSBox Pure.
Changes in 0.9.1:
- Fix gamepad mapper unable to map mouse left click (#57)

- Support holding scroll keys in menus (#57)
- Improve mounting and booting from hard disk images
