Blood Pill - a set of tools to manipulate with .BIG files. It can be used to view the data stored in pill.big - resources file of Blood Omen.

Blood Pill is able to decode all filetypes used in the game into readable/listenable form: speech sound, tile, sprite, tim graphich and more.

Feature list includes:

• Packing/Unpacking of .BIG files for PC and PSX versions of BO
• TIM<->TGA autoconversion during packing and unpacking
• RAW ADPCMWAV/OGG autoconversion during packing and unpacking
• Unpacking sprites (enemies and objects) to separate Targa pictures
• Unpacking tiles (level textures) to Targa pictures
• Unpacking the multiobject files ('merged' files that is used on some entries in BO)
• Decoding of .JAM video to Targa frames
• Decoding VAG files to WAV PCM/OGG sounds
• Decoding levels to Targa images (with optional developer info shown)
• Decoding levels into text-based format used by Blood Omnicide legacy loader (early version, still in development)
• Patching .big files
• Support for Blood Omnicide scripted installation

• Mean Person for figuring out Blood Omen's VAG internals
• Forest [LordHavoc] Hale for cmdlib and memlib
• Balder and Zench from XentaX community (www.xentax.com) for pill.big specs, advices
• Klarth (stevemonaco@hotmail.com) and Raul Sobon (Cheekyboy@2-hot.com) for TIM specs
• Andrey [Rackot] Grachev for bigfile specs
• Ben Lincoln for tile compression decoder
• MisterGrim for Jam Decoder

There are no known bugs as of yet since the active tool development is over. If you found any, let me know.

• New -bigfile -version command estimates pill.big version and sets return code: 1 is error occured, 0 is PlayStation bigfile, -1 is PC version bigfile, -2 is PC Sneak Peek Preview version.
• Klist.txt is built-in now (so it is removed from distrib).
• Font.tim is built-in now (so it is removed from distrib).
• Blood Omen maps: fully investigated the lighting format, added new -l/-maplighting switch which renders lighting on the map. Normally day is rendered. -a/-maptoggled switch (objects toggled state) renders night.
• Blood Omen maps: investigated the field storing music played for particular map.
• Updated mapfile.h (blood omen map format description). Added description for lights, effect flags, song names and map environment flag (indoor/outdoor).
• Berror.txt is now exported for warnings (for omnicide installer).
• Install script: added "bigfile" command to switch current bigfile.
• New icon.

• Fixed tinkering sound (actually a decoder error) in the end of unpacked PSX VAG files.

• Tighter check for bogus numentries in pill.big header. Increased PK3 pack buffer (100mb -> 150mb) as recent version of jPsxDec has slightly better quality at extracting FMV's.
• Can now attach external spr32 files to generated sprites in build script.
• Introduces blood omen .txt maps exporter (to play them in Blood Omnicide), plus tilemaps scaler.
• Added "pk3compression" option for script launcher to control per-entry compression ratio. It will be used for psx vids and ogg files extraction as compressing them is really just a waste of CPU time.
• Add SoX custom effect (-effect) switch to sound entry extraction.
• Rewritten help page.
• Removed spr32 command stage.
• Rawblock crop now saves frame offsets (which allows to generate correct Quake/Darkplaces sprite file from it)/
• New option "packsprite" for omnicide installer, which will generate a new packed sprites that uses atlas textures.
• Omnicide-related code are moved to separate omnilib/ folder.
• Cleaned up memory allocation utils.
• OmniLib are used to load and save .spr32 files (so dpspr32file.cpp will be removed in future).
• Fresh SoX build.

• Added early version of text-based map format exporter. Used by Blood Omnicde legacy loader.
• New key -f tga8_32 for -extract action enables exporting images with 32-bit palette (palette with alpha-channel), used by tiles.
• Fixed a crash in -extract action.
• Tile and TIM images extraction now supports -colorscale and -colorsub keys which scales rgb color, then subtracts a given 0-255 value from it.
• Renamed -colormapscale/-colormapsub into -colorscale/-colorsub for sprites extraction.
• Tile extraction now supports -scale2x and -scale4x magnification filter

• New key -mapsaveid for -unpack/-mapconvert stages, -s key for -extract action Shows entity/object save numbers when extracting map to Targa image.

• Fixed a crash when unpacking PS1 pill.big
• VAG speech are sorted to dirs defined in klist.txt just as RAW ADPCM

• Map files can be extracted to Targa images (shows base map layout, enemies items, speech marks, objects, doors, optionally solid zones, triggers, switchable tiles at state on/off etc.
• Cleaned up sprite extraction code

• New -sp prefix shich prints solid pacifier (used by installer)
• New action -bigfile -patch -outfile <new_bigfile.big> Patch file are text file with each line definina a single action : RAW/DEL/WAV2ADPCM <pill_big_file_hash_or_name> <path_to_a_new_file_contents> or (RAW replace, where filename should match some of original blood omen filenames or #hash)
• JAM->TGA converter (-jam action), thanks MisterGrim
• Fixed wrong name unhashing for some file which was producing override of 640x480 .htm fiels by 320x240 .tim.
• Fixed a rare bug with wrong extension for raw output files

• New prefix -c: (compact) dont print program caption
• New prefix -f: (function) dont print anything except for errors
• New prefix -cd: change to selected dir before start
• New prefix -ew: (errorwait) wait for key press on error
• Fixed crash when launched with wrong parms
• Fix mkdir when launched with full paths as parms
• Fix program return codes

• use static MSVC runtimes

• Fixed export of multi-chunk files (vortout.all and so on)
• Fixed all names of ADPCM speech files to be in right dirs
• New -script action for install script (used by Blood Omnicide installation)

• Code cleanups
• Optimized -pack action for speed
• file hashes are automatically converted to real file names (thanks Ben Lincoln and Andrey [Rackot] Crachev). By default internal hash/filename table are used, can be overriden by BO1.csv.
• Tiles unpacking (thanks Ben Lincoln for LZW unpacking)
• Support for PS1 pill.big unpacking (but not packing since there are no WAV->VAG/FAG converter)
• Extract action can handle real filenames, old hash filenames should be prefixed by # (example: #AD07E8F1)
• When unpacking, original files are stored in original/ folder.
• Null files (with empty contents) are not unpacked anymore
• Unpack action not unpacks fiels with real filenames (use -hashasnames to revenr to old behavior)
• Sample scripts improved
• Added filetypes.txt which brings together knowledge about all Blood Omen game file types.
• Better support fo PS1 pill.big extraction

• New -extract action which extracts a given file from pill.big
• Fix a frequent "cannot open file for writing" error
• Removed -vagconvert,-pcm,-ogg,-rawconvert,-noalign keys from -unpack action.
• New -adpcm2wav, -adpcm2pcm, -adpcm2ogg, -raw2tga, -rawnoalign as a replacement.

• Removed -srcdir option from -pack. Same as for -unpack.
• Removed -to key from -list action. Same as for -unpack.
• Removed -lowmem from -unpack, now always using low memory usage path.

• Now can unpack sprite frames (SHD, SDR, SHA files) into Targa pictures. Note that sprite unpacking creates VERY big amount of files (about 35000).
• Auto-align sprite frame size for easy creation of GIF.
• Documented -raw action (sprite unpacking)
• Fixed some memory leaks

• New -rawconvert key for -unpack action. Unpacks some sprites into Targa files.
• Default folder for each file type (.tim gues to tim/, .dat to unknown and so on)
• Better support for different pill.big versions
• Fixed broken pill.big -pack action ("wrong file type" error)

• Added -vagconvert key for -unpack action. Automatically converts .VAG/.FAG files into WAV or Ogg Vorbis (-ogg key) by SoX lib. Quality degrades during conversion.
• Backwards WAV/OGG -> ADPCM (.VAG/.FAG) conversion for -pack action.
• Simplify syntax for klist.txt. New "path" option to set additional output path.
• New -soxpath "path" key to set a different path to SoX program.
• Fixed null files sometimes being identified as TIM.
• Fixed wrong TIM layers unpacking for German version of BO
• Fixed segfail during -pack

• New -tim2tga for TIM->TGA conversion during -unpack. Optional -16to24 enables additional 16->24 bit conversion.

• bpill -bigfile "pill.big" -pack [-srcdir dir] pack unpacked contents back to a new bigfile.
• Known-files-list support to detect RAW ADPCM files
