+# MultiEmulator
+
+**MultiEmulator** - project for GoldSource Engine, which provides ability to generate tickets with a specific SteamID key, using all available emulators for this engine.
+
+Ticket is processed by the game server of Half-Life 1 and modifications using **DProto** or **ReUnion** modules. If the server does not have these modules, then MultiEmulator won't work.
+
+# Ticket generators
+
+Currently available ticket generators: 
+* OldRevEmu
+* AVSMP
+* Setti
+* SteamEmu
+* RevEmu
+* SC2009
+* RevEmu2013
+
+Currently under development generators:
+* SmartSteamEmu (SSE3)
+
+# How to use?
+Each file in the **MultiEmulator\Source\Emulators** folder contains a **Generate** function that writes a ticket to the **pDest** argument for the emulator of the same name as a header file. As a result of the function, the size of the written ticket is returned. If the generator can set an arbitrary SteamID, the function will have the **nSteamID** argument, in which the required SteamID is specified.
+
+# Examples
+As an example, the DLL was developed that searches InitiateGameConnection method in ISteamUser interface, which generates Steam ticket, and inserts in its place own generator, which creates RevEmu2013 ticket with SteamID equal to 3333333. You can find this project in **Example** folder, you just need to compile it and perform DLL injection in hl.exe process with any known injection method.

-In this mode, we emulate the behaviour of selected functions that may help running mods relying on engine bugs, but enabling them by default may break majority of other games.
 
 At this time, we only have implemented GoldSrc bug-compatibility. It can be enabled with `-bugcomp` command line switch.
 
+When `-bugcomp` is specified without argument, it enables everything. This behavior might be changed or removed in future versions.
+
+When `-bugcomp` is specified with argument, it interpreted as flags separated with `+`. This way it's possible to combine multiple levels of bug-compatibility.

 ## GoldSrc bug-compatibility
 
-### Emulated bugs
+| Flag    | Description | Games that require this flag |
-
+| ------- | ----------- | ---------------------------- |
-* `pfnPEntityOfEntIndex` in GoldSrc returns NULL for last player due to incorrect player index comparison
+| `peoei` | Reverts `pfnPEntityOfEntIndex` behavior to GoldSrc, where it returns NULL for last player due to incorrect player index comparison | * Counter-Strike: Condition Zero - Deleted Scenes |
-
+| `gsmrf` | Rewrites message at the moment when Game DLL attempts to write an internal engine message, usually specific to GoldSrc protocol. Right now only supports `svc_spawnstaticsound`, more messages added by request. | * MetaMod/AMXModX based mods |
-### Games and mods that require this
+| `sp_attn_none` | Makes sounds with attenuation zero spatialized, i.e. have a stereo effect. | Possibly, every game that was made for GoldSrc. |

+# Debugging your mod using minidump files (Windows only)
+Minidump files is awesome instrument for debugging your mod after it's being released, or for catch specific crashes which are presented only in one specific configuration, but doesn't happens in other configurations or even on developer machine. It contains a lot of information useful for debugging, and therefore it size is not so small: around hundreds or even thousands of megabytes. But this is not a problem, since minidump files compresses very effectively using common algorithms.
+There are short algorithm, explaining how to use this debugging instrument:
+
+1. User starts your mod with `-minidumps` startup parameter
+2. Finally, crash happened on user's machine, and minidump file being written. This file has `.mdmp` extension and located in same folder, where mod folder located
+3. User packs this minidump file to .zip/.7z archive, and somehow sends it to developer
+4. Developer just opens minidump file in Visual Studio, then a virtual debugging session is opened and now reasons of crash is pretty easy to detect: you can see call stack, local function variables and global variables, information about exception and a lot of other information
+
+You can find more information about minidumps in this [awesome article](https://learn.microsoft.com/en-us/windows/win32/dxtecharts/crash-dump-analysis?source=recommendations#writing-a-minidump).

+
+`ent_create monster_zombie targetname zomb1`

+   * setmodel: set entity model (does not update)
+   * set: set key/value by server library
+       * See game FGD to get list.
+       * command takes two arguments
+   * touch: touch entity by current player.
+   * use: use entity by current player.
+   * movehere: place entity in player fov.
+   * drop2floor: place entity to nearest floor surface
+   * moveup: move entity to 25 units up
+   * moveup (value): move by y axis relatively to specified value
+* Flags (Set/clear specified flag bit, arg is bit number):
+   * setflag
+   * clearflag
+   * setspawnflag
+   * clearspawnflag
+
+### ent_info
+Print information about entity by identificator
+
+`ent_info <identificator>`
+
+### ent_getvars
+Set client cvars containing entity information (useful for [[Scripting]]) and call ent_last_cb
+
+`ent_getvars <identificator>`
+
+These cvars are set:
+```
+ent_last_name
+ent_last_num
+ent_last_inst
+ent_last_origin
+ent_last_class
+```
+
+### ent_list
+Print short information about antities, filtered by pattern
+
+`ent_list <pattern>`
+
+## Syntax description
+
+### \<identificator\>
+
+* !cross: entity under aim
+* Instance code: !\<number\>_\<seria\l>
+ * set by ent_getvars command
+* Entity index
+* targetname pattern
+
+### \<pattern\>
+
+Pattern is like identificator, but may filter many entities by classname
+
+### (vector)
+
+used by ent_fire command. vector means three float values, entered without quotes
+
+### key/value
+
+All entities parameters may be set by specifiing key and value strings.
+
+Originally, this mechanizm is used in map/bsp format, but it can be used in enttools too.
+
+Keys and values are passed to server library and processed by entity keyvalue function, setting edict and entity owns parameters.
+
+If value contains spaces, it must be put in quotes:
+
+`ent_fire !cross set origin "0 0 0"`
+
+## Using with scripting
+
+ent_create and ent_getvars commands are setting cvars on client
+
+It can be used with ent_last_cb alias that is executed after setting cvars.
+
+Simple example:
+
+```
+ent_create weapon_c4
+alias ent_last_cb "ent_fire \$ent_last_inst use"
+```
+
+Use weapon_c4 after creating it.
+
+Note that you cannot use many dfferent callbacks at the same time.
+
+You can set entity name by by pattern and create special script, contatning all callbacks.
+
+Example:
+
+example.cfg
+```
+alias ent_last_cb exec entity_cb.cfg
+ent create \<class\> targetname my_ent1_$name
+ent_create \<class\> targetname my_ent2_$name
+```
+entity_cb.cfg
+```
+if $ent_last_name == my_ent1_$name
+:(ent1 actions)
+if $ent_last_name == my_ent2_$name
+:(ent2 actions)
+```
+Note that scripting cannot be blocking. You cannot wait for server answer and continue. But you can use small scripts, connected with ent_last_cb command. The best usage is user interaction. You can add touch buttons to screen or call user command menu actions by callbacks.
+##  Server side
+
+To enable entity tools on server, set sv_enttools_enable to 1
+
+To change maximum number of entities, touched by ent_fire, change sv_enttools_maxfire to required number.
+
+To enable actions on players, set sv_enttools_players to 1.
+
+To enable entity tools for player by nickname, set sv_enttools_godplayer to nickname. Useful to temporary enable from rcon.
+
+To prevent crash on some actions, set host_mapdesign_fatal to 0

+## Looping MP3 extension
+
+It is now possible to loop MP3 file in Xash3D FWGS by adding a custom text tag with `LOOP_START` or `LOOPSTART` in description and time point (in raw samples) in value.
+
+### Example with foobar2000
+1. Open Foobar2000
+2. Add your .mp3 file to playlist
+3. Right click to newly added file and select Properties
+4. In Metadata tab, at the bottom of the table, select "+add new"
+5. In newly added line replace `<60>input field name<6D>` with `LOOP_START` (without any symbols).
+6. Press Tab and enter loop time point in raw samples. For example, `0` will replay sound file from beginning to end indefinitely.
+
+### Possible alternatives
+1. Classic WAV files looping. HQ WAV files can take too much disk space, and recommended software supporting cue points is paid, outdated and can't run on modern systems. (Although there is alternative that's proven to work with idTech-based engines called LoopAuditioneer.)
+2. Vorbis looping through comment. Engine doesn't support Vorbis but this extension was highly inspired by this hack.
+
+### Known bugs and limitations
+1. At this time using MP3 as SFX requires complete decoding. This can cause noticeable stutters, so keep MP3 file length in mind.
+2. We deliberately only support modern ID3v2.3 and ID3v2.4 tags. Using ID3v1 is not possible.

+# sounds.lst.md
+
+Using sounds.lst located in scripts folder, modder can override some of the hardcoded sounds in temp entities and server physics.
+
+File format:
+```
+<group name>
+{
+	<path1>
+	<path2>
+	<path3>
+}
+
+<group2 name> <path with %d> <min number> <max number>
+```
+
+* Sounds can use any supported sound format (WAV or MP3).
+* The path must be relative to the sounds/ folder in the game or base directory root, addon folder, or archive root.
+* Groups can be empty or omitted from the file to load no sound.
+* Groups can either list a set of files or specify a format string and a range.
+* Anything after // will be considered a comment and ignored.
+* Behavior is undefined if the group was listed multiple times.
+
+Currently supported groups are:
+|Group name|Usage|
+|----------|-----|
+|`BouncePlayerShell`|Used for BOUNCE_SHELL tempentity hitsound|
+|`BounceWeaponShell`|Used for BOUCNE_SHOTSHELL tempentity hitsound|

+# Game definition and information file
+
+gameinfo.txt is an essential part of any Xash3D based game. It allows basic customization for games creators, like setting game title, DLL paths, etc.
+
+This document defines gameinfo.txt syntax, supported keys and liblist.gam conversion rules for the latest version of the engine. Note for engine developers, keep this document in sync with an implementation.
+
+## gameinfo.txt syntax
+
+* gameinfo.txt is a simple list of keys and values, separated by newline.
+* You can add single line comments using double slashes (//).
+* Keys can accept integer, float, string or boolean values.
+* Boolean keys use 0 as false and 1 as true value.
+* To have spaces in string values, you must enclose them in double quotes. Then, to have double quotes, you must escape it with backslash, and to have a backslash you need to use double backslashes.
+
+The example:
+```
+// this is a comment :)
+// this is another comment
+some_integer_key 123
+
+this_is_float_key 13.37 // optional comment
+
+enable_feature 1 // boolean, 1 to enable, 0 to disable
+
+example_string_key string_value
+example_spaces "string with spaces"
+example_title "Fate\\Stay Night" // engine will parse it as Fate\Stay Night
+```
+
+## gameinfo.txt keys
+
+This is a list of all gameinfo.txt keys supported by the engine. Be aware that the engine will silently skip all unrecognized keys.

+
+For game creators who plan supporting only Xash3D, using this file is not recommended.
+

+# Support for GoldSrc network protocol
+This feature is still work-in-progress, but for now it's available for all users, and we appreciate any bug-reports and contributions around it.
+
+For connecting to GoldSrc-based servers, use this command:
+```
+connect ip:port gs
+```
+
+But keep in mind, there are requirement for server to be able to accept connections from Xash3D-based clients: it should accept HLTV connections.
+Without this requirement, you will just get "Steam validation rejected" error on connecting.
+
+That is because proper authorization with Steam API is not implemented in engine yet (but we have plans on it).
+
+In case of ReHLDS with Reunion plugin, by default it rejects HLTV clients. But connections from HLTV can be easily enabled in `reunion.cfg` file.

+### HD (external) textures support
+
+Xash3D supports loading texture replacements in TGA format for almost all types of models in the game, except alias models at this time.
+
+Textures are expected to be located at:
+* `modfolder/materials/<mapname>` - for a specific map
+* `modfolder/materials/common` - common for all maps
+* `modfolder/materials/decals` - for decals
+* `modfolder/materials/models/<model>` - for models (texture name must match the internal texture name in the model)
+
+Support for high-resolution textures is enabled setting `host_allow_materials` cvar to `1` or in the menu, in "Video options" section.
+
+#### Xash3D FWGS additions
+
+In addition to paths above, Xash3D FWGS checks following paths:
+
+* `modfolder/materials/sprites/<sprite>` - for sprites, except HUD sprites
+
+Also, to check which texture replacements are loaded successfully, failed or weren't found, a mod developer can set `host_allow_materials` cvar value to `2`. The engine will spew log at any developer level in the following format:
+
+```
+Looking for <replacement> replacement... <status code> (<path relative to mod directory>)
+```
+
+Status codes:
+* `OK` - texture replacement file was found and loaded into GPU memory successfully
+* `FAIL` - texture file was found but hasn't been parsed or loaded successfully. Refer to engine log for more details.
+* `MISS` - texture file wasn't found
+
+Example:
+```
+Looking for maps/bounce.bsp:!waterblue tex replacement...OK (materials/common/!waterblue.tga)
+Looking for maps/bounce.bsp:!waterblue_luma tex replacement...MISS (not found)
+Looking for {shot2 decal replacement...MISS (materials/decals/{shot2.tga)

+## Porting client-side code
 
-## VGUI library
-
-Valve's client uses vgui library which is available only on x86 systems and has big amount of mistakes in headers. The best and simplest way of porting is removing VGUI dependency at all.
-Most singleplayer mods don't really use VGUI at all. It is used in multiplayer only to show score table and MOTD window
-
-## Porting 
-
-### First strategy: full port
-
-#### Basic port (Stage 1)
-* First, remove all files and headers which use vgui (contains "vgui" in file name).
-* After that, try to build it and remove vgui includes.
-* Remove all gViewPort usings.
-* Remove all CVoiceManager usings (xash3d does not support voice)
 * Redefine all DLLEXPORT defines as empty field (Place it under _WIN32 macro if you want to keep windows compatibility).
-* Remove hud_servers.cpp and Servers_Init/Servers_Shutdown from hud.cpp
+* Remove hud_servers.cpp and Servers_Init/Servers_Shutdown from hud.cpp.
 * Fix CAPS filenames in includes (like STDIO.H, replace by stdio.h).
-* Replace broken macros as DECLARE_MESSAGE, DECLARE_COMMAND by fixed examples from our hlsdk-xash3d port (cl_util.h)
+* Replace broken macros as DECLARE_MESSAGE, DECLARE_COMMAND by fixed examples from our hlsdk-portable port (cl_util.h).
-* Add ctype.h where it is need (tolower, isspace functions)
+* Add ctype.h where is needed (tolower, isspace functions).
-* Add string.h where it is need (memcpy, strcpy, etc)
+* Add string.h where is needed (memcpy, strcpy, etc).
-* Use in_defs.h from hlsdk_client
+* Use in_defs.h from hlsdk-portable.
-* Add scoreboard_stub.cpp and input_stub.cpp from hlsdk-xash3d to fix linking.
+* Add input_xash3d.cpp from hlsdk-portable project to fix input.
-Now your client should be able to build and work correctly. Add input_xash3d.cpp from hlsdk-xash3d project to fix input.
 
-#### Multiplayer fix (Stage 2)
+Now your client should be able to build and work correctly.
-Look at hlsdk-xash3d project.
 
-Main changes are:
+# Porting mod to hlsdk-portable
-* Add MOTD.cpp, scoreboard.cpp and input_xash3d.cpp
+Look at changes which was made.
-* Add missing functions to hud_redraw.cpp, hud.cpp and tri.cpp, fix class defination in hud.h
-* Remove duplicate functions from hud.cpp and HOOK_MESSAGE's for it
-* Remove +showscores/-showscores hooks from input.h
-* Fix cl_util.h
 
-### Second way: move mod to hlsdk-xash3d
+If there are not too much changes (for example, only some weapons was added), add these changes in hlsdk-portable.
-Look at changes you made in client.
 
-If there are not much changes (for example, only some weapons was add), add these changes in hlsdk-xash3d.
+You can use diff with original HLSDK and apply it as patch to hlsdk-portable.

+```
+NOTE: Many an old mods was made on HLSDK 2.0-2.1 and some rare mods on HLSDK 1.0.
+So you need to have different versions of HLSDK to make diffs.
+Plus different Spirit of Half-Life versions if mod was made on it.
+Also, weapons in old HLSDK versions does not use client weapon prediction system and you may be need to port standart half-life weapons to server side.
+```
 Files must have same line endings (use dos2unix on all files).
 
-I recommend to enable ignoring space changes in diff.
+We recommend to enable ignoring space changes in diff.
-### Writing Makefiles
 
-Use Makefile from hlsdk-xash3d as Makefile example.
+Move all new files to separate directories.
 
-Get .c and .cpp file lists from Visual Studio project and fill SRCS and SRCS_C variables to Makefile.
+# Possible replacements for non-portable external dependencies
+1. If mod uses **fmod.dll** or **base.dll** to play mp3/ogg on client-side or to precache sounds on server-side, you can replace it with:
+	- [pfnPrimeMusicStream](https://github.com/FWGS/hlsdk-portable/blob/master/engine/cdll_int.h#L293=) engine callback;
+	- [miniaudio](https://github.com/mackron/miniaudio);
+	- [phonon](https://community.kde.org/Phonon).
 
-Remove all files containing vgui in name from list, add missing include dirs.
+2. If mod uses **OpenGL**, porting code to Xash3D render interface is recommended.
+
+3. If mod uses **cg.dll**, you can try to port code to [NVFX](https://github.com/tlorach/nvFX).
+
+4. If mod uses detours, comment code or try to find replacement somehow by yourself.
+
+# Additional recommendations
+1. If mod uses STL, you can replace it with [MiniUTL](https://github.com/FWGS/MiniUTL).
+2. Avoid to use dynamic casts to make small size binaries.
+3. Avoid to use exceptions to make small size binaries.
+ 
+# Writing build scripts
+
+Use wscript/CMakeLists.txt files from hlsdk-portable as build scripts example.
+
+Get .c and .cpp file lists from Visual Studio project.
+
+Add missing include dirs.
 
-Do same for Android.mk if you are building for android.

+Xash3D FWGS works on `musl` out of the box. However, the engine doesn't try to differentiate glibc and musl anymore. If you see error similar to:
+
+```
+Host_InitError: can't initialize cl_dlls/client.so: Error relocating valve/cl_dlls/client.so: __sprintf_chk: symbol not found
+```
+
+... or you know that the game you're running is linked against glibc, you can try using `libgcompat`, like this:
+
+```
+$ LD_PRELOAD=/lib/libgcompat.so.0 ./xash3d ...
+```
+
+It will automatically add the missing symbols that glibc binaries usually need. In the future we might automatically link engine against `libgcompat` for better compatibility with prebuilt or closed-source games, if there will be any use for this.

+## PlayStation Vita port
+
+### Prerequisites
+1. Make sure your PSVita is [set up to run homebrew applications](https://vita.hacks.guide/).
+2. Install [kubridge](https://github.com/TheOfficialFloW/kubridge/releases/) by copying `kubridge.suprx` to your taiHEN plugins folder (usually `ux0:/tai`) and add it to your `config.txt`, for example:
+   ```
+   *KERNEL
+   ux0:tai/kubridge.skprx
+   ```
+3. Install `libshacccg.suprx` by following [this guide](https://cimmerian.gitbook.io/vita-troubleshooting-guide/shader-compiler/extract-libshacccg.suprx).
+
+### Installation
+1. If you have an old vitaXash3D install, remove it.
+2. Get `xash3d-fwgs-psvita.7z` from the latest [automatic build](https://github.com/FWGS/xash3d-fwgs/releases/tag/continuous).
+3. Install `xash.vpk` from the 7z archive onto your PSVita.
+4. Copy the `data` directory from the 7z archive to the root of your PSVita's SD card.
+5. Copy the valve folder and any other mod folders from your Half-Life install to `ux0:/data/xash3d/` (you can use other mountpoints instead of `ux0`). **Do not overwrite anything.**
+
+### Build instructions
+1. Install [VitaSDK](https://vitasdk.org/).
+2. Build and install [vitaGL](https://github.com/Rinnegatamante/vitaGL):
+    ```
+    git clone https://github.com/Rinnegatamante/vitaGL.git
+    make -C vitaGL NO_TEX_COMBINER=1 HAVE_UNFLIPPED_FBOS=1 HAVE_PTHREAD=1 SINGLE_THREADED_GC=1 MATH_SPEEDHACK=1 DRAW_SPEEDHACK=1 HAVE_CUSTOM_HEAP=1 -j2 install
+    ```
+3. Build and install [vita-rtld](https://github.com/fgsfdsfgs/vita-rtld):
+    ```
+    git clone https://github.com/fgsfdsfgs/vita-rtld.git && cd vita-rtld
+    mkdir build && cd build
+    cmake -DCMAKE_BUILD_TYPE=Release ..
+    make -j2 install
+    ```
+4. Build and install [this SDL2 fork](https://github.com/Northfear/SDL) with vitaGL integration:
+    ```
+    git clone https://github.com/Northfear/SDL.git && cd SDL
+    mkdir build && cd build
+    cmake -DCMAKE_TOOLCHAIN_FILE=${VITASDK}/share/vita.toolchain.cmake -DCMAKE_BUILD_TYPE=Release -DVIDEO_VITA_VGL=ON ..
+    make -j2 install
+    ```
+5. Use `waf`:
+    ```
+    ./waf configure -T release --psvita
+    ./waf build
+    ```
+6. Copy all the resulting `.so` files into a single folder:
+    ```
+    ./waf install --destdir=xash3d
+    ```
+7. `xash.vpk` is located in `build/engine/`.

 ## Installation & Running
 0) Get Xash3D FWGS binaries: you can use [testing](https://github.com/FWGS/xash3d-fwgs/releases/tag/continuous) build or you can compile engine from source code.
 1) Copy engine binaries to some directory.
 2) Copy `valve` directory from [Half-Life](https://store.steampowered.com/app/70/HalfLife/) to directory with engine binaries.
-If your CPU is NOT x86 compatible or you're running 64-bit version of the engine, you may want to compile [Half-Life SDK](https://github.com/FWGS/hlsdk-xash3d).
+If your CPU is NOT x86 compatible or you're running 64-bit version of the engine, you may want to compile [Half-Life SDK](https://github.com/FWGS/hlsdk-portable).
-This repository contains our fork of HLSDK and restored source code for some of the mods. Not all of them, of course.
+This repository contains our fork of HLSDK and restored source code for Half-Life expansions and some mods.
 You still needed to copy `valve` directory as all game resources located there.
 3) Run the main executable (`xash3d.exe` or AppImage).
 
 For additional info, run Xash3D with `-help` command line key.

-    make -f Makefile.linux XASH_DEDICATED=1
-
-To enable dll support on linux, build loader library:
-
-    cd ../loader
-    make -f Makefile.linux libloader.so libloader.a
-    cp libloader.so libloader.a ../engine/
-
-And built engine with XASH_DLL_LOADER=1:
-
-    cd ../engine
-    make -f Makefile.linux XASH_VGUI=1 XASH_SDL=1 XASH_DLL_LOADER=1
-
-or same for dedicated server
-
-    cd ../engine
-    make -f Makefile.linux XASH_DEDICATED=1 XASH_DLL_LOADER=1
-
-### Building engine in separate library
-
-Some old distros does not support hidden symbol visibility
-This results in crash when loading server library
-
-Building launch binary
-
-    cd (xash3d)/game_launch
-    gcc xash.c -o xash -ldl -lrt -lm
-
-Building engine library:
-
-    make -f Makefile.linux XASH_SINGLE_BINARY=0
-
-## Building on Windows
-
-### Visual Studio 2013 (recommended for Windows)
-
-Download latest prebuilt SDL2 from
-
-https://www.libsdl.org/release/SDL2-devel-2.0.4-VC.zip
-
-Unzip and rename `SDL2-2.0.4` folder to `SDL2` and put it next to xash3d project folder.
-
-    ..\xash3d\
-    ..\SDL2\
-
-Open `xash.sln` with Visual Studio 2013 and make a build. After building, copy contents of `Debug` or
-`Release` folder to directory you choose. Copy `valve` folder and `vgui.dll` from your Half Life game
-installation folder and `SDL2.dll` form `\SDL2\lib\x86\` to it.
-Move `vgui_support.dll` into `valve` folder.
-
-    ..\valve\
-    ..\valve\vgui_support.dll
-    ..\menu.dll
-    ..\SDL2.dll
-    ..\vgui.dll
-    ..\xash.dll
-    ..\xash.exe
-
-Now you good to go, just run `xash.exe`.
-
-### Visual Studio 6
-
-This is legacy configuration, but msvc6 seems to generate more stable and more effective code
-
-Setup your msvc6 enviroment, unpack SDL2-2.0.4 to xash3d folder and do:
-
-    cd (xash3d)\engine
-    ..\msvc6\build.bat
-    cd (xash3d)\game_launch
-    ..\msvc6\build_launch.bat
-
-### MinGW
-
-The most effective configuration, but maybe unstable.
-Setup your MinGW environment and run:
-
-    cd (xash3d)\engine\
-    CC=gcc mingw32-make -f Makefile.mingw
-
-    engine will be built to single exe binary
-
-## Building game mods
-
-### Linux
-
-#### microndk
-
-All mods that ported to android may be build to linux using Android.mk with microndk:
-
-[https://github.com/SDLash3D/microndk]
-
-Clone microndk repo somewhere, change xash3d_config to preffered configuration (change arch to x86
-for example)
-
-Go to dlls folder if you are building server or cl_dlls if you are building client and do:
-
-    make -f /path/to/microndk/microndk.mk -j4
-
-Do:
-
-    make -f /path/to/microndk/microndk.mk -j4 clean
-
-every time when you build client after building server
-
-#### Makefile.linux
-
-### Windows
-
-On windows common way is using Visual Studio as many mods does not correctly work with mingw.
-
-Just open project and build it.
-
-Other is using mingw and microndk, but it was not tested yet.
-
-hlsdk-xash3d based mods may work fine with mingw.
-
-You may use microndk to build it. Build process is very similar to linux one.
-
-After setting up MinGW enviroment, do:<br>
-`mingw32-make -f \path\to\microndk\Microndk.mk`
-
-to build 64-bit library, use:<br>
-`mingw32-make -f \path\to\microndk\Microndk.mk 64BIT=1`
-
-Edit xash3d_config.mk to set optimal CFLAGS if you are running server
-
-# Running
-
-Copy **valve** folder from Half-Life:
-
-    cp -r $HOME/.steam/steam/steamapps/common/Half-Life/valve $HOME/Games/Xash3D
-
-**NOTE**: If you build with CMake, you can now use `make install`. It will install binaries where
-they must be located. So just run `xash3d` from command line in directory where is gamedata is located.
-For additional info look to the CMakeLists.txt in repo root and xash3d.sh script.
-
-After a successful build, copy the next files to some other directory where you want to run Xash3D:
-
-    cp engine/libxash.so game_launch/xash3d mainui/libxashmenu.so $HOME/Games/Xash3D
-
-If you built it with XASH_VGUI, also copy vgui.so:
-
-    cp ../hlsdk/linux/vgui.so vgui_support/libvgui_support.so $HOME/Games/Xash3D
-
-Copy script:
-
-    cp ../xash3d.sh $HOME/Games/Xash3D
-
-Run:
-
-    cd $HOME/Games/Xash3D
-    ./xash3d.sh
-
-## Manual running
-
-Put xash3d binaries and vgui(optionally) to you game data directory and run:
-
-    LD_LIBRARY_PATH=. ./xash -dev 5
-
-## Running under GDB
-
-    LD_LIBRARY_PATH=. gdb --args ./xash -dev 5
-
-## Using DLL Loader
-
-Put vgui_support.dll from windows build to your game data folder and run:
-
-    LD_LIBRARY_PATH=. ./xash -dev 5 -vguilib vgui.dll -clientlib valve/cl_dlls/client.dll -dll dlls/hl.dll
-
-## Running MinGW builds
-
-Put exe file to your game data directory
-
-    cd (game)\
-    xash_bin -dev 5
-
-### Running MinGW builds under GDB
-
-    gdb --args ./xash_bin.exe -dev 5
-
-# Useful GDB commands
-
-Start or restart process:
-
-    (gdb) r
-
-Show backtrace:
-
-    (gdb) bt
-
-Full backtrace:
-
-    (gdb) bt full
-
-Continue execution:
-
-    (gdb) c
-
-Recover from segmentation fault:
-
-Skipping function:
-
-    (gdb) handle SIGSEGV nopass
-    (gdb) ret
-    (gdb) c
-
-Restart frame for beginning:
-
-    (gdb) handle SIGSEGV nopass
-    (gdb) jump *Host_AbortCurrentFrame
-Anti-Crash script (useful for scripting servers):
-```
-cd /path/to/rootdir
-file xash
-set args xash -dev 5 -nowcon
-handle SIGSEGV nopass
-catch signal SIGSEGV
-set $crashes=0
-commands
-print $crashes++
-if $crashes > 500
-set $crashes=0
-run
-else
-jump *Host_AbortCurrentFrame
-end
-end
-run
-```
