Code base refactor + major performance and readability improvement. Read description for details. * Codebase restructured to SourceSDK codebase style and .cpp/.h assertion paths in the game executable. * Document most functions with valve style 'Purpose' blocks. * Rename variables to match the rest of the codebase and Valve's naming convention. * Dedicated DLL and the SDKLauncher now share the same codebase as the DevSDK. * Obtain globals or pointers directly instead of waiting for runtime initialized data. * Dynamically search for all functions and globals (this doesn't count for dedicated yet!). * Initialize most in-SDK variables. * Move certain prints and other utilities under ConVars to reduce verbosity and increase performance. * Print all pattern scan results through a virtual function to make it easier to add and debug new patterns in the future. * Type global var pointers appropriately if class or type is known and implemented. * Forward declare 'CClient' class to avoid having 2 'g_pClient' copies. * Add IDA's pseudo definitions for easier prototyping with decompiled assembly code. * RPAK decompress Command callback implementation. * Load decompressed RPaks from 'paks\Win32\' overriding the ones in 'paks\Win64\' (the decompress callback will automatically fix the header and write it to 'paks\Win32\'). * VPK decompress Command callback implementation. * Move CRC32 ands Adler32 to implementation files. * Server will print out more details about the connecting client. * Upgrade ImGui lib to v1.86. * Don't compile id3dx.h for dedicated. * Don't compile id3dx.cpp for dedicated * Implement DevMsg print function allowing to print information to the in-game VGUI/RUI console overlay, ImGui console overlay and the external windows console * Fixed bug where the Error function would not properly terminate the process when an error is called. This caused access violations for critical/non-recoverable errors. * Fixed bug where the game would crash if the console or server browser was enabled while the game was still starting up. * Several bug fixes for the dedicated server (warning: dedicated is still considered work-in-progress!).

Client token authentication implementation The game internally obtains a auth token from Origin. On connect to a gameserver, it will send it to the masterserver. The master server will create a JWT token and send this back to the client. The client stores this token in 3 userinfo cvars (token, sig1, sig2). the sig1 and sig2 cvars are there to compensate for the truncation caused by sending the cvar, as each cvar string length could be up to 255 (byte max). The server verifies this token (the signature, timestamp, expiry); if they are valid, the has successfully authenticated and will connect.

Fix >190FPS input system/simulation problems Function 'CL_Move' has been fully rebuild in the SDK. Originally, the game checked if the delta time exceeded an amount defined by an immediate value, and dropped usercmd's if that was the case. This logic has been replaced with a more dynamic solution, and the console variable regulating this ('fps_input_max') is set to 200.0 by default (the same as the fix applied in the Season 9.1 Genesis update). This function also has been slightly optimized by removing duplicate operations that were performed in the original function. A second fix has been applied to 'CInput::JoyStickApplyMovement' that was also found changed in the Season 9.1 Genesis executable. In that function, an extraneous clamp was performed on the frame time causing viewstick problems when usercmd's get dropped in CL_Move.

Major cleanup (see description) * Fix all compiler error for GameSDK on S0 and S1. * Remove some unused patterns and globals (launch performance gains of 100ms). * Remove most duplicate patterns. * Relocate globals from engine to a more appropriate location. * Renamed some unknown vars to a more appropriate name (most of these where obtained a while back, but as we reversed more parts of the engine, some of these vars become known). * Renamed some vars to fit the naming convention used in the SDK. * Fixed pattern debug logging using the wrong pointer, thus displaying the wrong address.

inline void(*CClientState__RunFrame)(CClientState* thisptr);
Client token authentication implementation The game internally obtains a auth token from Origin. On connect to a gameserver, it will send it to the masterserver. The master server will create a JWT token and send this back to the client. The client stores this token in 3 userinfo cvars (token, sig1, sig2). the sig1 and sig2 cvars are there to compensate for the truncation caused by sending the cvar, as each cvar string length could be up to 255 (byte max). The server verifies this token (the signature, timestamp, expiry); if they are valid, the has successfully authenticated and will connect.

This instructs the client to only update the remote statistics; actual tick members won't get updated as this causes simulation problems.

Start of migration to IDetour interface Migrating to this to initialize all patterns and prototypes in Systems_Init() instead. This should make debugging missing/not found patterns easier and allow for opting out variable/constant search (some of these require other patterns to be found, thus resulting in seg faults..). Also added check to detect if user has a eligible CPU to run this SDK. The game requires SSE and SSE2 instruction sets. Our SDK requires this too due to the use of SSE intrinsics, so we cannot let the game handle this. We have to check it ourselves.
