Exploiting Social Club Authentication: Bypassing Issuer Checks (b2060 - b2802)

Important Not for the Mod Name This mod will be changing its name from "EXE Integrity Bypass Against RGL," which will also be applied to archives since v1.1. About This ASI program bypasses/disables the issuer check that GTA5.exe does, which is done by communicating with socialclub.dll. As a result, you can avoid the game refusing to start with the error code 16 for using a version of the exe older than the game build 2824. With this plugin, you can disassemble GTA5.exe for b2699 or older while running working game environments for one of the versions, where compiler's RTTI info is present. You don't need to use this ASI for v1.0.2824.0 or newer ones because the game don't check the issuer at all in those versions. For your information, this tool supports all the versions that use Rockstar Games Launcher (tested in b2060, b2372, b2699, and b2802 of Steam version), but this does not support any versions that use the old Social Club system (so this tool doesn't do the job in b1868 or earlier). You can use this tool in v2824 or newer, but this tool does not offer anything meaningful than the complete vanilla game in that case since the issuer check doesn't exist at all in those versions. If you are wondering, after the patch job is finished, the ASI will detach itself from GTA5.exe and will not occupy the memory or have the lock for the ASI file any longer. Note To avoid executing the unpatched code, this program will try to patch with another thread and the created thread will keep the main thread suspended until the patch completes (actually yoinked from GTAVLauncherBypass but I changed the code to suspend only one thread). So if the patch fails half done, the game may not get started infinitely. If Rockstar patch this tool by not even launching a process of GTA5.exe if the exe is not the latest one, this tool can do nothing since the tool can't be loaded in that case (I doubt that will happen since the issuer check is less restricted in later game builds according to what alloc8or said). You can see ExeIntegrityBypassAgainstRGL.log created or updated if the ASI runs and the exe has the permission to write to the root folder (won't update the log if the permission is insufficient as logging is not mandatory). You will need appropriate update.rpf files (at least appropriate ysc script files) for the GTA5.exe you are planning to use (e.g. update.rpf for game build 2699 for the b2699 of GTA5.exe) because hashes for native functions are actually changed in most updates (but no native hash update between b2612 and b2699 at least). Requirements The ASI loader. Script Hook V is not needed. Although this requires Visual C++ Redistributable 2019+ to run, You should have Visual C++ Redistributable 2019 installed already when you installed Rockstar Games Launcher. **Source Code** Can be found on GitHub, which is licensed under BSD Zero Clause License, where you can do basically anything against the source code but not a public domain dedication (so some parties such as Google can use some piece of code) and without liability and warranty. I don't want to keep this thing secret or protected with copyright. Some part of source code is redundant since I made this tool in a bit of a hurry To use the mod, simply place the ASI file into your GTA V directory.
