what is retrostash fr?

RetroStash is an Android app built for retro gaming fans and archivists who want to pull files from Archive.org onto their device. It lets you browse Archive.org collections, use AI to filter and sort large result lists with plain language prompts, and download files directly with handling built for handheld gaming consoles. Search covers more than just game roms: it also supports PC games, books, movies, audio, and images, each with its own tailored search query builder. The AI filtering, powered by Google's Gemini model, lets you type something like only RPGs or USA region only and have the list narrowed and sorted automatically instead of scrolling through everything by hand. The interface is built to work well on both portrait phones and landscape handheld consoles such as the Anbernic RG556 and RG557, switching to a two column grid layout in landscape to make better use of the screen. On the download side, the app actively monitors its queue, automatically extracts ZIP archives, and safely moves files that are not ZIPs or that fail extraction instead of deleting them, so nothing gets silently lost. If one download fails, the queue unblocks itself and moves on to the next item rather than getting stuck. There is also a metadata and box art system that scans your downloaded collection, uses AI to identify which console a game belongs to and clean up its title, and generates a gameList.xml file plus named box art images following Libretro's conventions, along with a Clear Finished option to tidy up completed and failed downloads. To use it you need an Android device running Android 8.0 or newer and a free Gemini API key from Google AI Studio, which you enter in the app's settings along with the destination folder where you want files saved. It is built with Kotlin and Jetpack Compose for the interface, Retrofit, OkHttp, and Ktor for networking, and WorkManager alongside Android's DownloadManager for background downloads and unzipping.
