This thread is meant to discuss the general purpose of DOSBox CVS builds, which known public ones exist, and where to get them. The first part is a FAQ covering various DOSBox CVS-related questions, is followed by a listing, description of, and links to known CVS builds, and finally a selection of related useful links.

Feel free to post any questions or suggestions in response to this thread, but be advised that replies are purged occasionally to keep the thread clean.

Please refer to the very last section if you are a maintainer or forum moderator.

What are CVS builds?

CVS builds are versions of dosbox.exe that people have built from the latest version of the DOSBox source code, which is stored on <a href="" target="_blank"></a> in something called a CVS repository. CVS builds contain changes that have been made by Qbix and Harekiet since the latest official release. Some enhanced CVS builds also contain unofficial features and fixes that have been created by enthusiasts in the DOSBox development community.

Why should I get a CVS build?
As of this writing, the latest official release version of DOSBox is 0.72. Active development continues, however, so new features and fixes will continue to be added to DOSBox's CVS repository. If you're having trouble running a game with the DOSBox release, it's worth trying a CVS build to see if the problem has since been addressed. You may also want access to the new features or optimizations if you are having compatibility or performance issues.

Which one should I get?
That's up to you. Consult the list below to see which features the different builds contain and decide which one you want to try first. If you are interested in getting a CVS build in hopes that it will fix a problem you're having in the latest release version, you should probably start with a "plain" (no-enhancements) CVS build like the AEP one. Also, see replies to this post from the maintainers for additional info on their builds.

How do I use it?
First, install the latest official release of DOSBox. Then, unpack the CVS build over the top of it, replacing the release versions of the files with the CVS versions. Some developers also recommend regenerating your dosbox.conf configuration file so that you will see any new config options that have been added. Consult <a href="">this thread</a> for info on how to regenerate a config file.

What do I do if I find bugs in a CVS build?
First, search these forums to see if it's already been reported. If it hasn't, post as much information as possible (see the <a href="">help request guidelines</a>).

Update: Note that bugs in plain CVS builds are probably the only ones of interest to the DOSBox devs (QBix and Harekiet). Problem reports for the other builds should be addressed to their respective maintainers, as problems could be caused by experimental patches that aren't part of the official CVS source code.

The following CVS builds are based directly off of the official DOSBox CVS source code.

Use these builds to test the latest official CVS changes.

Tharos' builds *** daily builds seem to have stopped as of 3/28/10 ***
Last updated: March 28, 2010
URL: <a href="" target="_blank"></a>
Description: A direct build (i.e. no modifications or unofficial patches) from the official CVS source code. Good for testing games that have problems in the latest release version to see if they've since been fixed in CVS.

The following CVS builds contain additional fixes and/or features that are not officially part of DOSBox.

Many people prefer them due to the included extra features that are not included in in the CVS. Note that if you have problems with these builds, it may be due to the unofficial changes that have been made by their maintainers and not the official DOSBox code itself that is to blame.

Moe's (Linux)
Last updated: December 15, 2006
URL: <a href="" target="_blank"></a>

Description: Recently Moe has decided to provide a DOSBox Linux (x86, 32-bit, Athlon64-optimized) binary including some useful patches. It is built against latest CVS and includes at least these patches: addkey, adlib optimize, Innovation SSI-2001, Self-Modifying-Code optimizations, SVGA chipsets, CD-Image cycling, Glide emulation, Printer emulation.
Moe is also the creator of OPENGL-HQ. OPENGL-HQ is another scaler that is implemented in SDL.dll. Unfortunately it may be some time (or never), until OPENGL-HQ is implemented in the official SDL so until then you'll have to download it from here (or compile it yourself). Neat thing about this is that you can use this SDL.DLL with any SDL program (e.g. DOSBox, SCUMMVM...).
