+# 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.

+//Rijndael (pronounced Reindaal) is a block cipher, designed by Joan Daemen and Vincent Rijmen as a candidate algorithm for the AES.

+//key length and block length are possible). Both block length and key length can be extended very easily to
+// multiples of 32 bits.
+//Rijndael can be implemented very efficiently on a wide range of processors and in hardware.

+# 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.
