GameVault v1.1.6

GameVault v1.1.6 — My Added Games, GOG DLC manager, artwork scan

My Added Games (formerly the "RPG Maker" tab)

The native-games tab is now a general drop-folder for far more than RPG Maker. Drop a game folder in and it's auto-detected and added to Steam as a native shortcut, in this order:

RPG Maker → ScummVM → DOS → Linux → Electron → Windows

• RPG Maker MV/MZ → NW.js, VX Ace/XP/VX → mkxp-z (native, no Proton)
• ScummVM / DOS → ScummVM / DOSBox Staging flatpaks
• Linux builds run their native binary/.sh; Electron/NW.js via NW.js; Windows .exe via Proton
• Wrong guess? Drop a one-word .gvengine file in the folder to force the engine (mv mz vxace xp vx scummvm dos linux electron windows).
• Bundled a codec-enabled libffmpeg so MV title/cutscene videos (H.264/AAC) play instead of showing black.

Auto-rename: the drop folder is now Games/AddedGames (was Games/RPGMaker). On update it migrates itself automatically — your games move over and existing Steam shortcuts keep working (identity-preserving, with a back-compat symlink).

GOG DLC manager

• New Install/Remove DLCs entry in a game's gear/settings menu: lists every DLC with per-DLC Install and Remove.
• Removal deletes only the DLC's own files (never base-game/shared files) and keeps gogdl's manifest cache honest so a later reinstall works. DLCs that replace existing game files (uncensor/patch DLC) can't be fully reverted — a note in the manager explains this.
• "Install DLCs with game" setting (GOG tab): turn it off to install the base game only, then add DLCs one at a time.

Fixes: GOG installs

• Installs no longer hang at 99% — tolerate the gogdl progress-bar crash that struck at 100% and left games un-finalized.
• DLC (re)install actually downloads — pass --with-dlcs to enable and --dlcs to target, and prune a removed DLC from the cached manifest so reinstall isn't a silent no-op.

Artwork scan (SteamGridDB)

• New Fetch Artwork (SteamGridDB) action (tab's sliders menu) applies grid/hero/logo art to all listed added games at once, matched by name.
• Confident name matching so it won't apply the wrong game's art, a proper User-Agent so the SteamGridDB CDN stops rejecting downloads, corrected artwork-slot mapping, and per-image fault isolation.
• Requires a free SteamGridDB API key (Settings → SteamGridDB → API Key). Coverage depends on what SGDB actually has — well-known titles fill; many niche games aren't on SGDB.
