Woof!

Woof! is a source port developed by Fabian Greffrath forked from WinMBF. Woof! is developed based on the WinMBF code with the aim to make MBF, originally by Lee Killough, more widely available and convenient to use on modern systems.

To achieve this goal, Woof! is less strict regarding its faithfulness to the original MBF. It is focused on quality-of-life enhancements, bug fixes and compatibility improvements. However, all changes have been introduced in good faith that they are in line with the original author's intentions and even for the trained eye, this source port should be hard to distinguish from the original MBF.

Woof!'s name was inspired by Doom's logo turned upside down, which spells Wood. As this would be a rather silly name, it was thus named Woof, after the barking sound dogs make, and a reference to Marine's Best Friend.

Main Features

 * The code has been made 64-bit compatible.
 * The code has been ported to SDL-2, the game scene is now rendered to screen using hardware acceleration (if available).
 * The level building code has been upgraded to use unsigned data types internally, which allows for loading maps that have been built in "extended nodes" format. Furthermore, maps using nodes in DeePBSP and (compressed or uncompressed) ZDBSP formats can now be loaded.
 * The renderer has been upgraded to use 32-bit integer variables internally, which fixes crashes in levels with extreme heights or height differences (e.g. ludicrm.wad MAP03).
 * Fullscreen mode can be toggled in the General menu section or by pressing Alt+Enter, and it is now saved in the config file.
 * The complete SDL input and event handling system has been overhauled based on code from Chocolate Doom 3.0.
 * The search path for IWADs has been adapted to modern requirements, taking the install locations for common download packages into account.
 * On Windows systems, support for dragging and dropping WAD and Dehacked files onto the executable has been added.
 * Screenshots may be saved in PNG format if the SDL2_Image library is found at runtime.
 * The sound system has been completely overhauled, using SDL_Mixer.
 * The original Spectre/Partial invisibility effect has been brought back.
 * The flashing disk icon has been brought back.
 * Support for helper dogs and beta emulation from MBF is now unconditionally enabled.
 * Modern WASD movement scheme by default.
 * Playback of Vanilla Doom demos has been vastly improved.
 * Support for the Doom 3: BFG Edition IWAD files.
 * Support for the Freedoom IWAD files.

History
Woof! formerly started development on December 11, 2019, when Fabian Greffrath in a Doomworld thread titled: "WinMBF goes 64 bit (WinMBF64 aka 3.0)" mentioned in a to "have started my own branch to achieve 64-bit compatibility meanwhile". A first preliminary 64 bit test build, still named WinMBF, came nine days later in this. It was labeled.

A second build labeled as in this  released on January 10, 2020. It was a 32 bit build, and required the libraries that shipped with Greffrath's other port, Crispy Doom. The port then changed its name to the now official Woof! moniker with version through this, which got released on January 21, 2020. It still required the SDL libraries shipped with Crispy.

One final test build would follow exactly one month later on February 21, 2020, when Fabian released a build adhering to version 1.0 but labeled in this. After recieving enough feedback, Greffrath then officially announced Woof! version 1.0.0 in a Doomworld thread titled: "This is Woof! 1.0.0 (Feb 28, 2020) [Updated WinMBF]".
