When running under Wine/Proton on Linux, the anticheat module (netc.dll) detects Wine via wine_get_version in ntdll.dll and triggers a fail-fast exception (0xC0000409). The loader interprets this as an integrity violation and blocks startup. Changes in Client/loader/MainFunctions.cpp: - Set MTA_UNDER_WINE environment variable before launching GTA so child processes (loader-proxy, core.dll, netc.dll) can detect Wine and adjust behavior. - Skip the hardcoded MD5 file hash integrity check under Wine. System DLLs like D3DX9_42.dll, d3dcompiler_*.dll provided by Wine may have different hashes, causing false positives. This is the first step toward full Wine compatibility. loader-proxy/main.cpp should also be updated to hide the wine_get_version export before loading netc.dll.

What this fix is for: Linux players are facing errors when launching the client, and there is an error with a integrity violation. I am further investigating the client for any issues with launching it through Wine. |

It requires a lot of research, and I started getting an error with the GTA SA process, which failed to start the process correctly during testing. I need to check the details. |

I am not sending the project for merging, as the loader requires additional work. |

Fixes #4783
Problem:
Under Wine/Proton on Linux, MTA:SA crashes at startup with integrity violation error.
Additional issue: hardcoded MD5 file hash check compares system DLLs (D3DX9_42.dll, d3dcompiler_*.dll) which differ under Wine, causing false positives.
Changes in Client/loader/MainFunctions.cpp:
