in-game guide feature for OnionOS

RetroMod Guides is a free browser tool that adds the best English GameFAQs walkthrough next to every recognized ROM on your retro handheld's SD card without uploading any files. It works locally in Chrome or Edge by matching ROM names to a 17,400-game GameFAQs index and saves the guides as plain .txt files directly on your card for easy in-game reading. Compatible with popular handhelds like Anbernic and others, it requires no sign-up, preserves your existing files, and respects privacy by keeping everything on your device. The tool is open source, runs without ads, and provides quick access to classic walkthroughs for retro gaming enthusiasts.
