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 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, DOSBox ECE, DOSBox Staging, DOSVAX/DOSVAXJ3, and vDosPlus, 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 was designed and maintained by Wengier.

The DOSBox-X Wiki pages were created and updated by Wengier and rderooy.
