SteaMidra helps you set up games to work with Steam using Lua scripts, manifests, and LumaCore. It writes the right files into your Steam folder so games and DLC can run. It does not replace or crack Steam itself.

Features
- Download and use Lua files for games, download manifests, and set up LumaCore.
- Write Lua and manifest data into Steam's config.
- LC Online Fix — toggle
-onlinefix on a chosen App ID in localconfig.vdf. Closes Steam first, picks the active SteamID3 from loginusers.vdf, navigates the VDF tree case-insensitively. LumaCore handles the appid-480 redirect at launch so the overlay, Steam Input, and screenshots still tag the real game.
- Multiplayer Fix — searches online-fix.me for the selected game and opens the result in your browser. SteaMidra no longer stores online-fix credentials or downloads files from the site.
- Fixes & Bypasses — searches a curated list from the CrakFiles repo on GitHub and applies the chosen fix to the game folder. No API key, no account. Achievement-safe — only adds bypass DLLs, leaves the Steam API intact.
- DLC status check, cracking (gbe_fork), SteamStub DRM removal (Steamless), and DLC Unlockers (CreamInstaller-style: SmokeAPI, CreamAPI, Uplay).
- Multi-language GUI — English and Portuguese built-in; add more via
sff/locales/.
- Parallel downloads, backups, recent files, and settings export/import.
- Linux support — SLSSteam ID management, platform-aware MIDI, and Linux-compatible auto-update.
- Store tab — ⭐ THIS IS THE MAIN WAY TO DOWNLOAD GAMES. Browse Hubcap's manifest library to find games, refresh depot keys, and download either the latest version through Steam or older/specific versions through DepotDownloaderMod (.NET 9 required, slower). Search runs when you press Enter or the Search button so the tab stays smooth.
- Main tab "Download Game" — Downloads the latest version of a game directly from Steam (fast, no .NET required for Windows OS). Processes the Lua file, writes decryption keys, copies the Lua to
config/stplug-in/ and the manifests to depotcache/ so LumaCore picks the game up immediately, then triggers Steam to download the game files natively. Use this for 99% of games.
Quick start
Step 1: SteaMidra
Download the latest installer from here and run it. The installer auto-creates the install folder, sets up file associations, and registers the uninstaller.
If the installer fails or your AV blocks it, grab the ZIP instead — SteaMidra-x.x.x-windows.zip. Extract anywhere, run SteaMidra_GUI.exe from inside the extracted folder.
Do not run SteaMidra yet. Complete Steps 2 and 3 first so all folders exist before first launch.
Step 2: LumaCore
Open SteaMidra, go to the Home tab, click Auto LC Setup, then click Install LumaCore. SteaMidra downloads the latest LumaCore release from GitHub and installs dwmapi.dll + LumaCore.dll into the Steam folder, removing old GreenLuma files automatically.
If the install fails, ask on Discord.
Step 3: Launch Steam
Run SteaMidra_GUI.exe and add a game on the Home tab. LumaCore makes it appear in the Steam library immediately. See the User Guide for how to add games.
Running from source (Python)? See the Python Setup Guide.
Linux quick start
LumaCore is a Steam-client DLL hijack and is Windows-only. On Linux, SteaMidra uses SLSsteam (license/family-share injection) plus SLScheevo (achievement-only Steam client) instead. Manifests, depot keys, and ACFs work the same as on Windows.
Step 1: Download the Linux build
Grab SteaMidra-x.x.x-linux.zip (or the AppImage) from the releases page and extract it. CachyOS, Arch, Debian, Ubuntu, Fedora, and Steam Deck Desktop Mode are all supported.
Step 2: Set up SLSsteam + SLScheevo
Launch SteaMidra, open Quick Tools, run Set up Linux tools (SLSsteam + .NET 9). SteaMidra installs SLSsteam into ~/.steam/steam/ (or whichever Steam install it found), drops SLSteam.so and library-inject.so, and verifies your .NET 9 runtime is on PATH (DepotDownloaderMod needs it).
If the GUI reports SLSteam libraries not found: SLSteam.so, library-inject.so, the install step has not run yet — open Quick Tools and run it.
Step 3: Add a game
Add a game on the Home tab the same way as Windows. SteaMidra writes the lua to config/stplug-in/, drops the manifests, registers depot keys, and writes the ACF. Restart Steam from inside SteaMidra so SLSsteam injects into the new Steam process — without injection, ownership and family bypass do not work.
For the full walkthrough (supported distros, troubleshooting, what files go where, Steam-Deck-specific notes), see docs/LINUX_SETUP.md.
GUI features
SteaMidra has a full graphical interface with a Modern UI and the classic Qt interface.
Modern UI — the new default interface, built with QWebEngine. Accessible from a clean sidebar with 7 tabs: Home (game picker with auto-refresh), Store (search/browse Hubcap, grid/list, pagination), Library (installed games), Downloads (live progress + history), Fix Game (full emulator pipeline), Cloud Saves (scan/backup/restore, Google Drive, rclone with 17 provider shortcuts, All Save Locations), and Settings. Supports 11+ themes, tooltips, and toast notifications.
What the GUI gives you:
- Tabbed interface — Main, Store, Downloads, Fix Game, Tools, and Cloud Saves tabs.
- Pick your game from a dropdown (all Steam libraries scanned) or set a path for games outside Steam.
- All actions as buttons: crack, DRM removal, DLC check, multiplayer fix, Fixes & Bypasses, DLC unlockers, and more.
- Store browser — search and browse the Hubcap Manifest library with pagination. Download opens a version picker with full depot/manifest history, and the Depot Keys button refreshes the local provider cache. Force Refresh bypasses cache to rebuild historical manifests.
- Fix Game pipeline — automate emulator application (Goldberg, ColdClient, ColdLoader) with SteamStub unpacking.
- Cloud Saves — Steam userdata plus Ludusavi save-path backup/restore. Multiple save folders for the same App ID are grouped into one backup with per-source restore details and a safety backup before overwrites. Supports local folder, Google Drive (sign in once), and rclone (Dropbox, OneDrive, MEGA, S3, Backblaze B2, SFTP, and 70+ other backends).
- Lua/manifest processing and library tools all accessible from buttons.
- Full settings dialog where you can edit, delete, export, and import all settings.
- 11+ themes including Dracula, Nord, Cyberpunk, and more.
- System tray icon for quick show/hide and exit.
- Multi-language support — switch between English and Portuguese in Settings (more locales can be added).
- Log viewer — "Logs" button in the menu bar (right of Help) opens a floating window showing all log output from every tab (Fix Game, Store, Tools, and more). Filterable by level (DEBUG/INFO/WARNING/ERROR), with Clear and Copy All buttons.
- Any prompts that would normally appear in the terminal show up as dialog boxes instead.

Any remaining SMD-derived parts remain credited to their original authors/contributors and are not claimed as original SteaMidra code.
LumaCore – Windows DLL hook library bundled with SteaMidra. Injects into Steam at startup via a dwmapi.dll proxy, reads Lua files from Steam/config/stplug-in/, and patches Steam's in-memory license tables so games appear owned without AppList files or Steam restarts. LumaCore
