Credits ======= Jonathan Campbell, the maintainer of DOSBox-X does not claim to have written all of the code in this project. The purpose of this document is to try to build a comprehensive list of source code in this repository that was borrowed from other projects. The base code is from the [DOSBox](https://www.dosbox.com) project in which most of the SVN commits made since 2011 were incorporated into DOSBox-X. This code had since been heavily modified by the DOSBox-X project. Some of the source code also came from other projects such as [DOSBox SVN Daum](http://ykhwong.x-y.net), [DOSBox ECE](https://dosboxece.yesterplay.net/), [DOSBox Staging](https://dosbox-staging.github.io/), [DOSVAX](http://radioc.web.fc2.com/soflib/dosvax/dosvax.htm)/[DOSVAXJ3](https://www.nanshiki.co.jp/software/dosvaxj3.html), and [vDosPlus](http://www.vdosplus.org/), with major works from other developers and contributors of DOSBox-X such as Wengier, aybe, Allofich, and rderooy. A list of features ported from DOSBox SVN Daum (maintainer: ykhwong): * GUI menu bar (heavily improved since then) * Some commands (PROMPT, MOUSE, VOL, DEVICE, etc) * Basic support for automatic drive mounting (Windows) * Printer output (improved since then by Wengier) * NE2000 Ethernet (improved since then by Wengier) * MT-32 emulation (MUNT; updated to newer version since then by Wengier) * Internal 3dfx Voodoo card emulation (improved since then by Wengier and joncampbell123 along with code ported from DOSBox ECE) * Some support for FluidSynth MIDI synthesizer * Improved PC Speaker emulation accuracy * CGA with Monochrome Monitor Support * Support for CPU types like Pentium Pro * Features such as V-Sync, xBRZ scaler, overscan border and stereo-swap * Various patches such as DBCS and font patch A list of features ported from DOSBox ECE (maintainer: YesterPlay): * Support for FLAC, MP3, WAV, OGG Vorbis and Opus CD-DA tracks (with some decoders ported and cleaned up from DOSBox Staging and DOSBox Optionals by Wengier) * Support for mapping mouse buttons to keyboard * Improved support for 3dfx emulation (Glide wrapper and improved internal card emulation; both improved since then by Wengier) * Improved support for FluidSynth MIDI synthesizer (internal FluidSynth support added for Windows by Wengier) * Updated Nuked OPL3 to 1.8 A list of features ported from DOSBox Staging (maintainers: dreamer and kcgen): * AUTOTYPE command for scripted keyboard entry (improved since then by Wengier) * LS command (heavily improved since then by Wengier) * Basic support for VMware mouse protocol and CuteMouse wheel API * Support for phonebook and ENET reliable UDP for modem emulation * Support for changing key bindings in runtime (improved since then by Wengier) A list of features ported from DOSVAX (maintainer: akm) and DOSVAXJ3 (maintainer: nanshiki): * Support for JEGA/AX machine type (imported from DOSVAX and DOSVAXJ3, cleaned up with some improvements by Wengier) * Support for DCGA and Toshiba J-3100 system type (imported by nanshiki and Wengier from DOSVAXJ3) * Support for DOS/V service (imported from DOSVAXJ3 and then extended by Wengier, including support for non-Japanese DOS/V modes) * Support for system input methods (IMEs) in Windows/Linux SDL1 builds (SDL-IM-plus by the DOSVAXJ3 maintainer, cleaned up and improved by Wengier) A list of features ported from vDosPlus (maintainer: Wengier): * Long filename support (improved for FAT drives since then by Wengier and joncampbell123) * TrueType font (TTF) output support (originally by Jos Schaars and heavily improved since then by Wengier) * Improved support for automatic drive mounting (Windows; improved since then by Wengier) * Support for clipboard copy and paste (improved since then by Wengier) * Several shell improvements (improved since then by Wengier) Features such as save & load states and Pentium MMX instructions were also ported from community contributions and have since been heavily improved by the DOSBox-X project. The [DOSBox-X website](https://dosbox-x.com) was designed and maintained by Wengier. The [DOSBox-X Wiki](https://dosbox-x.com/wiki) pages were created and updated by Wengier and rderooy.
