Wolf4SDL by Moritz "Ripper" Kroll (http://www.chaos-software.de.vu) Original Wolfenstein 3D by id Software (http://www.idsoftware.com)

Wolf4SDL is an open-source port of id Software's classic first-person shooter Wolfenstein 3D to the cross-plattform multimedia library "Simple DirectMedia Layer (SDL)" (http://www.libsdl.org). It is meant to keep the original feel while taking advantage of some improvements mentioned in the list below.

Main features:

• Cross-plattform: Supported operating systems are at least:

  • Windows 98, Windows ME, Windows 2000, Windows XP, Windows Vista (32 and 64 bit)
  • Linux
  • BSD variants
  • KallistiOS (used for Dreamcast) Only little endian platforms like x86, ARM and SH-4 are supported, yet.

• AdLib sounds and music: This port includes the OPL2 emulator from MAME, so you can not only hear the AdLib sounds but also music without any AdLib-compatible soundcard in near to perfect quality!

• Multichannel digitized sounds: Digitized sounds play on 8 channels! So in a fire fight you will always hear, when a guard opens the door behind you ;)

• Higher screen resolutions: Aside from the original 320x200 resolution, Wolf4SDL currently supports any resolutions being multiples of 320x200 or 320x240, the default being 640x400. Unlike some other ports, Wolf4SDL does NOT apply any bilinear or similar filtering, so the graphics are NOT blurred but pixelated just as we love it.

• Fully playable with only a game controller: Wolf4SDL can be played completely without a keyboard. At least two buttons are required (shoot/YES and open door/NO), but five or more are recommended (run, strafe, ESC).

Additional features:

• Two additional view sizes: Wolf4SDL supports one view size using the full width of the screen and showing the status bar, like in Mac-enstein, and one view size filling the whole screen (press TAB to see the status bar).

• (Nearly) unlimited sound and song lengths: Mod developers are not restricted to 64kB for digitized sounds and IMF songs anymore, so longer songs and digitized sounds with better quality are possible.

• Resuming ingame music: When you come back to the game from the menu or load a save game, the music will be resumed where it was suspended rather than started from the beginning.

• Freely movable pushwalls: Moving pushwalls can be viewed from all sides, allowing mod developers to place them with fewer restrictions. The player can also follow the pushwall directly instead of having to wait until the pushwall has left a whole tile.

• Optional integrated features for mod developers: Wolf4SDL already contains the shading, directional 3D sprites, floor and ceiling textures, high resolution textures/sprites, parallax sky, cloud sky and outside atmosphere features, which can be easily activated in version.h.

The following versions of Wolfenstein 3D data files are currently supported by the source code (choose the version by commenting/uncommenting lines in version.h as described in that file):

• Wolfenstein 3D v1.1 full Apogee
• Wolfenstein 3D v1.4 full Apogee (not tested)
• Wolfenstein 3D v1.4 full GT/ID/Activision
• Wolfenstein 3D v1.0 shareware Apogee
• Wolfenstein 3D v1.1 shareware Apogee
• Wolfenstein 3D v1.2 shareware Apogee
• Wolfenstein 3D v1.4 shareware
• Spear of Destiny full
• Spear of Destiny demo
• Spear of Destiny - Mission 2: Return to Danger (not tested)
• Spear of Destiny - Mission 3: Ultimate Challenge (not tested)

How to play:

To play Wolfenstein 3D with Wolf4SDL, you just have to copy the original data files (e.g. *.WL6) into the same directory as the Wolf4SDL executable. Please make sure, that you use the correct version of the executable with the according data files version as the differences are hardcoded into the binary!

On Windows SDL.dll and SDL_mixer.dll must also be copied into this directory. They are also available at http://www.chaos-software.de.vu

If you play in windowed mode (--windowed parameter), press SCROLLLOCK or F12 to grab the mouse. Press it again to release the mouse.

Usage:

Wolf4SDL supports the following command line options: --help This help page --tedlevel Starts the game in the given level --baby Sets the difficulty to baby for tedlevel --easy Sets the difficulty to easy for tedlevel --normal Sets the difficulty to normal for tedlevel --hard Sets the difficulty to hard for tedlevel --nowait Skips intro screens --windowed Starts the game in a window --res Sets the screen resolution (must be multiple of 320x200 or 320x240) --resf Sets any screen resolution >= 320x200 (which may result in graphic errors) --bits Sets the screen color depth (Use this when you have palette/fading problem or perhaps to optimize speed on old systems. Allowed: 8, 16, 24, 32, default: "best" depth) --joystick Use the index-th joystick if available --joystickhat Enables movement with the given coolie hat --samplerate Sets the sound sample rate (given in Hz) --audiobuffer Sets the size of the audio buffer (-> sound latency) (given in bytes) --ignorenumchunks Ignores the number of chunks in VGAHEAD.* (may be useful for some broken mods)
