Improve performance in DOSBox

Edit DOSBox configuration file
  • Change output=surface to output=openglnb
  • Change memsize=16 to memsize=64
  • Change core=normal to core=dynamic
  • Change cycles=auto to cycles=max
  • Change aspect=false to aspect=true

Blood Launcher

Build Game DOSBox Launcher

The Build Game DOSBox Launcher {OBSOLETE} allows installation from both digital release and retail release. It also includes a large number of optional modifications and custom maps.

Mouse fixes


bMouse is a DOS extension which improves mouse looking by removing the mouse filter which causes issues related to both axis not updating properly.

Choose either method to use it:

Declare bMouse as an external device[4]
  1. Unzip bmouse.exe into <path-to-game>.
  2. Run setup.exe through DOSBox and go to Controller Setup, then Choose Controller Type and select Keyboard and External.
  3. Go to Setup External and change the program name to BMOUSE.EXE. Save and exit.
Run Blood through bMouse[4]

Open dosboxBlood_single.conf in a text editor and replace the line containing BLOOD.EXE with bmouse.exe launch blood.exe.

The same can be done with Cryptic Passage by opening dosboxBlood_Addon.conf and replacing CRYPTIC.EXE with bmouse.exe launch cryptic.exe.
bMouse will cause the vertical aiming to be inverted. To fix this just go to Setup Advanced Control Options from Control Setup, then in Advanced Mouse Setup change the Mouse Y Scale to negative number.


Buildmfx is a patch which improves mouse looking. Unlike bMouse, it modifies the game executable.
Patch the executable with Buildmfx[5]
  1. Download the patch.
  2. Unzip the archive where BLOOD.EXE is located.
  3. Enter the command BUILDMFX.EXE BLOOD.EXE
This is a one-time set-up.
Enter the command BUILDMFX.EXE BLOOD.EXE /u to revert the executable to its original state.

Issues fixed

HUD flashes

  1. Download the patch.
  2. Unzip the archive where BLOOD.EXE is.
  3. Rename nolfblim.ren2com to NOLFBLIM.COM.
  4. Run NOLFBLIM.COM before launching Blood.
Automate these steps by adding NOLFBLIM.COM before the line calling BLOOD.EXE in the DOSBox configuration file's autoexec section.

Damage scaling changes after loading a save

Use a modified executable[10]

Patch BLOOD.EXE with this patcher.


Freezes damage scaling to the Still Kicking setting, which makes the game easier on higher difficulties.
An alternate but complex workaround can be found here.
This issue is fixed in the source ports and Blood: Fresh Supply re-release.

Mods and source ports installation guides


BloodCM is a Blood remake in the form of a mod for EDuke32, a Duke Nukem 3D source port that provides modern features such as widescreen resolutions and dynamic lighting.

Blood GDX for Build GDX

From the same creator as the aforementioned Blood CM, Blood GDX is a Blood remake made after the libGDX program from Java based on the Blood Alpha source code. It provides modern features such as widescreen, dynamic lighting, mouse freelook, and more. Since March 2019, it has been consolidated into Build GDX alongside other Build engine games remakes and decompilations.
How to play Blood GDX via Build GDX
  1. Download and unfold BuildGDX(_with_JRE).zip on the desired location.
  2. Open your Build GDX folder and create a Blood subfolder.
  3. Copy and paste the following files from your Blood game to the Blood subfolder: BLOOD.INI, BLOOD.RFF, all the CP[number].MAP, CPART07.AR_, CPART15.AR_, all the CPBB[number].MAP, CPSL.MAP, CRYPTIC.INI, CRYPTIC.SMK, CrypticPassage.kpf, GTI.SMK, LOGO.SMK, MAPEDIT.INI, SOUNDS.RFF, SURFACE.DAT, TABLES.DAT, all the TILES[number].ART, and VOXEL.DAT. If you have the original disk or Fresh Supply, you can also copy and paste the blood[number].ogg to play with the original soundtrack.
  4. Open BuildGDX.exe and choose Blood on the left: if no file is found, click on the three dot icon and look for your Blood file, or simply select the vanilla game's location on your PC.
  5. Configure your visual and audio preferences in the settings accessible via the down-right gear icon. If you want to install mods, you can put them in the autoload subsubfolder of the Blood subfolder, then choose to "Enable "autoload" folder" in the settings. Click on Back once you've finished.
  6. Click on Play Blood to launch the game.


All the files are required for the mod to work and no file can be forgotten to play Cryptic Passage.
Blood GDX maintains the autolook feature from vanilla Blood when your character goes upstairs or downstairs.
Once you took all the files from the original game, you can reuse them as many times as you need.
The cutscenes don't play on the latest version without this patch.


Raze compiles and enhances various Build Engine games decompilations by using GZDoom: as explained on the Blood wiki, Raze remakes Blood via NBlood and uses OpenGl to enhance its 3D graphics.
How to play Blood via Raze
  1. Download and unfold raze_[Current Version].zip on the desired location.
  2. Open your raze_[Current Version] folder and create a Blood subfolder.
  3. Copy all files from your Blood game to the Blood subfolder: blood.ini, *.rff, *.art, *.dat, and all the files from the movies subfolder. For the cutscenes, copy the gti.smk and logo.smk from the latter subfolder into your Blood subfolder for Raze. If you want the CD soundtrack, copy all the blood[number].ogg files in the subfolder.
  4. To play Cryptic Passage, copy movies/cryptic.smk, movies/cryptic.wav, cp*.map, cpart07.ar_, cpart15.ar_, cryptic.ini in another folder of your PC, select them all and compress them into a zip file, then put it into the Blood subfolder for Raze.
  5. Open raze.exe, choose BLOOD: One Unit Whole Blood (BLOOD) or BLOOD: Cryptic Passage (cryptic), configure your settings, and launch the game.


All the aforementioned files are required for the mod to work.
Once you took all the files from the original game, you can reuse them as many times as you need.
While the forum gives the instructions for the cutscenes to work, they don't play on the latest version.

  1. 1.0 1.1 1.2 1.3 File/folder structure within the installation folder reflects the path(s) listed for DOS game data. For the release, file changes in DOSBox are redirected to <path-to-game>/cloud_saves/ even if GOG Galaxy is not used (this folder contains all redirected files, so some files in the cloud_saves folder might be temporary files or other files that do not contain saves or settings).
  2. 2.0 2.1 File/folder structure within this directory reflects the path(s) listed for Windows and/or Steam game data (use Wine regedit to access Windows registry paths). Games with Steam Cloud support may store data in ~/.steam/steam/userdata/<user-id>/299030/ in addition to or instead of this directory. The app ID (299030) may differ in some cases. Treat backslashes as forward slashes. See the glossary page for details.
