It is a clone of the [RE-UE4SS](https://github.com/UE4SS-RE/RE-UE4SS) proxy (same 143 exports, forwarding,\n`--disable-ue4ss` / `--ue4ss-path` / `override.txt`) plus an in-DLL installer/updater.\n\n## Install\n\n```\n\u003cGame\u003e\\Binaries\\Win64\\dwmapi.dll            this proxy\n\u003cGame\u003e\\Binaries\\Win64\\ue4ss\\updater.ini     config\n```\n\nLaunch the game; UE4SS is downloaded and installed/updated automatically.\n\n## How it works\n\nOn `DLL_PROCESS_ATTACH`:\n\n1. Load `System32\\dwmapi.dll` and wire up the 143 export forwarders.\n2. Honour `--disable-ue4ss` (forward only).\n3. On a worker thread: read `ue4ss\\updater.ini`, resolve the target release on\n   GitHub, and if needed download the `UE4SS_*.zip` asset, extract the selected\n   components into `ue4ss\\`, then load `UE4SS.dll`. Failures are logged to\n   `ue4ss\\updater.log`; the game still launches with the installed UE4SS.\n\n## Config (`ue4ss\\updater.ini`)\n\n- `channel` — `stable` / `nightly` / `pinned` (+ `pinned_tag`).\n- `[modules]` — allow-list of components to install; also synced to `Mods\\mods.txt`\n  enable flags. A mod not listed is not installed.\n- `overwrite_settings` / `overwrite_mods_txt` — overwrite existing config files\n  (otherwise written only when missing).\n- `download_retries` — retry count for stalled/dropped downloads (with resume).\n- `check_interval_days` — `0` checks every launch, `N` at most once per N days.\n- `enabled = false` — disable the updater (pure proxy).\n\n## Build\n\nRequires Visual Studio 2022 (MSVC + MASM).\n\n```\nbuild.bat            full build  -\u003e dist\\dwmapi.dll\nbuild.bat skeleton   proxy only (no updater)\n```\n\nBuild artifacts go to `%TEMP%\\UE4SS-Bootstrap-build`; the DLL is copied to\n`dist\\dwmapi.dll` and the default config to `dist\\ue4ss\\updater.ini`.\n\n## Layout\n\n```\nsrc\\dllmain.cpp          proxy + updater entry\nsrc\\proxy_exports.*       export table / jump stubs (generated)\nsrc\\proxy_generated.inc   mProcs[] + setup_functions() (generated)\nsrc\\updater.*             config, GitHub API, download, extract, versioning\nsrc\\progress.*            progress window\nsrc\\ini.hpp               INI reader / writer\nsrc\\miniz.*               vendored zip library (public domain)\ntools\\gen_proxy.py        regenerates the export files from dwmapi.exports\nconfig\\updater.ini        default config (shipped to dist\\ue4ss\\)\n```\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Falexz006%2Fue4ss-bootstrap","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Falexz006%2Fue4ss-bootstrap","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Falexz006%2Fue4ss-bootstrap/lists"}
