Spark: The Essential Tool for Managing Ren'Py Visual Novels Spark is an independent utility for organizing and launching Ren'Py visual novels. It is not affiliated with or supported by the official Ren'Py project. For any issues with this app, please contact Spark support, not the Ren'Py team. Launch and Play Your Novels with Ease Import and start your favorite Ren'Py visual novels directly in Spark. Once added, your titles are ready to launch with a tap, so you can focus on reading and playing instead of manual setup. Tailored Compatibility for Each Novel Choose from multiple Ren'Py engine versions to match your novel and improve stability: 8.x: 8.5.4, 8.5.2, 8.5.0, 8.4.1, 8.3.7, 8.3.4, 8.2.3, 8.1.3, 8.0.3 7.x: 7.8.8, 7.8.4, 7.7.3, 7.6.3, 7.5.3, 7.4.11 Per-novel configuration lets you: - Select the best Ren'Py version for each title - Fine-tune settings to improve quality of life. - Improve performance on complex or older games Note: Performance and compatibility vary by novel. Older titles or very large games may contain bugs or fail to run. Smaller devices can experience rendering issues. Some novels may not work at all, though we strive to support as many as possible. Powerful Save Management Take full control of your progress across all novels: - View all saves in one place instead of hunting through folders - Backup saves before big choices or endings so you can revisit them anytime - Restore old saves if something breaks or you want to replay a specific branch - Import saves from other devices and delete unwanted saves to keep things tidy Organize Your Entire Library Keep your Ren'Py collection clean and easy to navigate: - See all installed novels at a glance - Rename titles to match your personal library style - Manage multiple versions of the same novel, such as different language patches or updated builds Flexible Novel Import Add new novels from a variety of common formats: - Import from zip, apk, 7z, tar, or rar files - Quickly bring in titles from backups, downloads, or other devices Once imported, novels become part of your Spark library with version and save management ready to use.
