3 The previous release (v1.1.0) included a bug that broke compilation
4 when libsamplerate support was enabled. The only change in this
5 version is to fix this bug.
9 * The video mode code has been radically restructured. The video mode is
10 now chosen by directly specifying the mode to use; the scale factor is
11 then chosen to fit the screen. This is helpful when using widescreen
12 monitors (thanks Linguica)
13 * MSVC build project files (thanks GhostlyDeath and entryway).
14 * Unix manpage improvements; the manpage now lists the environment
15 variables that Chocolate Doom uses. Manpages have been added for
16 chocolate-setup and chocolate-server, from the versions for the Debian
17 Chocolate Doom package (thanks Jon Dowland).
18 * INSTALL file with installation instructions for installing Chocolate
20 * Support for high quality resampling of sound effects using
21 libsamplerate (thanks David Flater).
22 * A low pass filter is applied when doing sound resampling in an
23 attempt to filter out high frequency noise from the resampling
25 * R_Main progress box is not displayed if stdout is a file (produces
27 * Client/server version checking can be disabled to allow different
28 versions of Chocolate Doom to play together, or Chocolate Doom
29 clients to play with Strawberry Doom clients.
30 * Unix manpages are now generated for the Chocolate Doom
32 * The BSD PC speaker driver now works on FreeBSD.
35 * Use the same spechits compatibility value as PrBoom+, for consistency
37 * The intercepts overrun code has been refactored to work on big
39 * The default startup delay has been set to one second, to allow
40 time for the screen to settle before starting the game (some
41 monitors have a delay before they come back on after changing modes).
42 * If a savegame buffer overrun occurs, the savegame does not get saved
43 and existing savegames are not overwritten (same behaviour as
47 * Desync with STRAIN demos and dehacked Misc values not being set
48 properly (thanks Lemonzest)
49 * Don't grab the mouse if the mouse is disabled via -nomouse or use_mouse
50 in the configuration file (thanks MikeRS).
51 * Don't center the mouse on startup if the mouse is disabled (thanks
53 * Reset the palette when the window is restored to clear any screen
54 corruption (thanks Catoptromancy).
55 * mus2mid.c should use MEM_SEEK_SET, not SEEK_SET (thanks Russell)
56 * Fast/Respawn options were not being exchanged when starting netgames
57 (thanks GhostlyDeath).
58 * Letterbox mode is more accurately described as "pillarboxed" or
59 "windowboxed" where appropriate (thanks MikeRS)
60 * Process affinity mask is set to 1 on Windows, to work around a
61 bug in SDL_mixer that can cause crashes on multi-core machines
63 * Bugs in the joystick configuration dialog in the setup tool have
68 This release is dedicated to Dylan 'Toke' McIntosh, who was
69 tragically killed in a car crash in 2006. I knew Dylan
70 from IRC and the Doomworld forums for several years, and he had
71 a deep passion for this game. He was also a huge help for me while
72 developing Chocolate Doom, as he helped point out a lot of small
73 quirks in Vanilla Doom that I didn't know about. His death is a
76 This is the first release to reach full feature parity with
77 Vanilla Doom. As a result, I have made this version 1.0.0, so
78 Chocolate Doom is no longer beta!
81 * Multiplayer! This version includes an entirely new multiplayer
82 engine, based on a packet server architecture. I'd like to thank
83 joe, pritch, Meph and myk, and everyone else who has helped test
84 the new code for their support, feedback and help in testing this.
85 The new code still needs more testing, and I'm eager to hear any
87 * A working setup tool. This has the same look and feel as the
88 original setup.exe. I hope people like it! Note that it has
89 some advantages over the original setup.exe - for example,
90 you can use the mouse.
93 * New mus conversion code thanks to Ben Ryves. This converts the
94 Doom .mus format to .mid a lot better. As one example, tnt.wad
95 Map02 is now a lot closer to how Vanilla says. Also, the music
96 on the deca.wad titlescreen now plays!
97 * x3, x4 and x5 display scale (thanks to MikeRS for x5 scale).
98 * Fullscreen "letterbox" mode allows Chocolate Doom to run on machines
99 where 1.6:1 aspect ratio modes are unavailable (320x200/640x400).
100 The game runs in 320x240/640x480 instead, with black borders.
101 The system automatically adjusts to this if closer modes are
103 * Aspect ratio correction: you can (also) run at 640x480 without black
104 borders at the top and bottom of the screen.
105 * PC speaker sound effect support. Chocolate Doom can output real
106 PC speaker sounds on Linux, or emulate a PC speaker through the
108 * Working three-screen mode, as seen in early versions of Doom!
109 To test this out, put three computers on a LAN and type:
110 chocolate-doom -server
111 chocolate-doom -autojoin -left
112 chocolate-doom -autojoin -right
113 * Allow a delay to be specified on startup, to allow the display to
114 settle after changing modes before starting the game.
115 * Allow the full path and filename to be specified when loading demos:
116 It is now possible to type 'chocolate-doom -playdemo /tmp/foo.lmp'
118 * Savegames are now stored in separate directories depending on
119 the IWAD: eg. the savegames for Doom II are stored in a different
120 place to those for Doom I, Final Doom, etc. (this does not affect
122 * New mouse acceleration code works based on a threshold and
123 acceleration. Hopefully this should be closer to what the DOS
124 drivers do. There is a 'test' feature in the setup tool to help
126 * New '-nwtmerge' command line option that emulates NWT's '-merge'
127 option. This allows TiC's Obituary TC to be played.
128 * The ENDOOM screen no longer closes automatically, you have to click
129 the window to make it go away.
130 * Spechit overrun fixes and improvements. Thanks to entryway for
131 his continued research on this topic (and because I stole your
132 improvements :-). Thanks to Quasar for reporting a bug as well.
133 * Multiple dehacked patches can be specified on the command line,
134 in the same way as with WADs - eg. -deh foo.deh bar.deh baz.deh.
135 * Default zone memory size increased to 16MB; this can be controlled
136 using the -mb command-line option.
137 * It is now possible to record demos of unlimited length (by default,
138 the Vanilla limit still applies, but it can now be disabled).
139 * Autoadjusting the screen mode can now be disabled.
140 * On Windows, the registry is queried to detect installed versions of
141 Doom and automatically locate IWAD files. IWADs installed through
142 Steam are also autodetected.
143 * Added DOOMWADPATH that can be used like PATH to specify multiple
144 locations in which to search for IWAD files. Also, '-iwad' is
145 now enhanced, so that eg. '-iwad doom.wad' will now search all
146 IWAD search paths for 'doom.wad'.
147 * Improved mouse tracking that should no longer lag. Thanks to
148 entryway for research into this.
149 * The SDL driver can now be specified in the configuration file.
150 The setup tool has an option on Windows to select between
153 * Configuration file option to change the sound sample rate.
154 * More than three mouse buttons are now supported.
156 Portability improvements:
157 * Chocolate Doom now compiles and runs cleanly on MacOS X. Huge
158 thanks go to Insomniak who kindly gave me an account on his machine
159 so that I could debug this remotely. Big thanks also go to
160 athanatos on the Doomworld forums for his patience in testing
161 various ideas as I tried to get Chocolate Doom up and running
163 * Chocolate Doom now compiles and runs natively on AMD64.
164 * Chocolate Doom now compiles and runs on Solaris/SPARC, including
165 the Sun compiler. Thanks to Mike Spooner for some portability
167 * Improved audio rate conversion, so that sound should play properly
168 on machines that don't support low bitrate output.
171 * Check for IWADs in the same order as Vanilla Doom.
172 * Dehacked code will now not allow string replacements to be longer than
173 those possible through DOS dehacked.
174 * Fix sound effects playing too loud on level 8 (thanks to myk
175 for his continued persistence in getting me to fix this)
176 * Save demos when quitting normally - it is no longer necessary to
177 press 'q' to quit and save a demo.
178 * Fix spacing of -devparm mode dots.
179 * Fix sky behavior to be the same as Vanilla Doom - when playing in
180 Doom II, the skies never change from the sky on the first level
181 unless the player loads from a savegame.
182 * Make -nomouse and config file use_mouse work again.
183 * Fix the -nomusic command-line parameter. Make the snd_sfxdevice
184 snd_musicdevice values in the configuration file work, so that it
185 is possible to disable sound, as with Vanilla.
186 * Repeat key presses when the key is held down (this is the Vanilla
187 behavior) - thanks to Mad_Mac for pointing this out.
188 * Don't print a list of all arguments read from response files - Vanilla
190 * Autorun only when joyb_speed >= 10, not >= 4. Thanks to Janizdreg
192 * Emulate a bug in DOS dehacked that can overflow the dehacked
193 frame table and corrupt the weaponinfo table. Note that this means
194 Batman Doom will no longer play properly (identical behavior
195 to Vanilla); vbatman.deh needs to also be applied to fix it.
197 * Allow dehacked 2.3 patches to be loaded.
198 * Add more dehacked string replacements.
199 * Compatibility option to enable or disable native key mappings. This
200 means that people with non-US keyboards can decide whether to use
201 their correct native mapping or behave like Vanilla mapping (which
202 assumes all keyboards are US).
203 * Emulate overflow bug in P_FindNextHighestFloor. Thanks to
204 entryway for the fix for this.
205 * Add -netdemo command line parameter, for playing back netgame
206 demos recorded with a single player.
207 * The numeric keypad now behaves like Vanilla Doom does.
208 * Fix some crashes when loading from savegames.
209 * Add intercepts overrun emulation from PrBoom-plus. Thanks again
210 to entryway for his research on this subject.
211 * Add playeringame overrun emulation.
214 * Fix crash when starting new levels due to the intermission screen
215 being drawn after the WI_ subsystem is shut down (thanks
217 * Catch failures to initialise sound properly, and fail gracefully.
218 * Fix crasher in 1427uv01.lmp (thanks ultdoomer)
219 * Fix crash in udm1.wad.
220 * Fix crash when loading a savegame with revenant tracer missiles.
221 * Fix crash when loading a savegame when a mancubus was in the middle
223 * Fix Doom 1 E1-3 intermission screen animations.
224 * Fix loading of dehacked "sound" sections.
225 * Make sure that modified copyright banners always end in a newline
226 - this fixes a bug with av.wad (thanks myk)
227 * Added missing quit message ("are you sure you want to quit this
229 * Fix when playing long sound effects - the death sound in marina.wad
230 now plays properly, for example.
231 * Fix buffer overrun on the quicksave prompt screen that caused a
232 mysterious cycling character to appear.
233 * IDCLEV should not work in net games (thanks Janizdreg)
234 * Stop music playing at the ENDOOM screen.
235 * Fix sound sample rate conversion crash.
236 * Fix 'pop' heard at the end of sound effects.
237 * Fix crash when playing long sounds.
238 * Fix bug with -timedemo accuracy over multi-level demos.
239 * Fix bug with the automap always following player 1 in multiplayer
240 mode (thanks Janizdreg).
244 NWT-style merging command line options (allows Mordeth to be played)
245 Unix manpage (thanks Jon Dowland)
246 Dehacked improvements/fixes:
247 * Allow changing the names of graphic lumps used in menu, status bar
248 intermission screen, etc.
249 * Allow changing skies, animated flats + textures
250 * Allow changing more startup strings.
251 * Allow text replacements on music + sfx lump names
252 Fix for plutonia map12 crash.
253 Fix bug with playing long sfx at odd sample rates.
254 Big Endian fixes (for MacOS X). Thanks to athanatos for helping
256 Install into /usr/games, rather than /usr/bin (thanks Jon Dowland)
260 Imported the spechit overrun emulation code from prboom-plus. Thanks to
261 Andrey Budko for this.
262 New show_endoom option in the chocolate-doom.cfg config file allows
263 the ENDOOM screen to be disabled.
264 Chocolate Doom is now savegame-compatible with Vanilla Doom.
266 Fixes for big endian machines (thanks locust)
267 Fixed the behavior of the dehacked maximum health setting.
268 Fix the "-skill 0" hack to play without any items (thanks to Janizdreg
269 for pointing out that this was nonfunctional)
270 Fix playing of sounds at odd sample rates (again). Sound effects at
271 any sample rate now play, but only sounds with valid headers.
272 This is the *real* way Vanilla Doom behaves. Thanks to myk for
273 pointing out the incorrect behavior.
277 Silence sounds at odd sample rates (rather than bombing out); this
278 is the way Vanilla Doom behaves.
279 Handle multiple replacements of the same sprite in a PWAD.
280 Support specifying a specific version to emulate via the command line
282 Fix help screen orderings and skull positions. Behave exactly as
283 the original executables do.

288 Dehacked "Misc" section support.
291 * Doom 1 skies always using Episode 1 sky
292 * Crash when switching applications while running fullscreen
293 * Lost soul bounce logic (do not bounce in Registered/Shareware)
294 * Mouse buttons mapped incorrectly (button 1 is right, 2 is middle)
295 * Music not pausing when game is paused, when using SDL_mixer's
296 native MIDI playback.
297 * Pink icon on startup (palette should be fully set before anything is
304 Fix bug with invalid MUS files causing crashes
308 Application icon and version info included in Windows .exe files
309 Fixes for non-x86 architectures
310 Fix uac_dead.wad (platform drop on e1m8 should occur when all
311 bosses die, not just barons)
312 Fix "loading" icon to work for all graphics modes
315 Mouse acceleration code to emulate the behaviour of old
316 DOS mouse drivers (thanks to Toke for information about
317 this and suggestions)
318 Lock surfaces properly when we have to (fixes crash under
322 Remove temporary MIDI files generated by sound code.
323 Fix sound not playing at the right volume
324 Allow alt-tab away while running in fullscreen under Windows
325 Add second configuration file (chocolate-doom.cfg) to allow
326 chocolate-doom specific settings.
327 Fix switches not changing in Ultimate Doom
