ANDSemu vs MindSpark

ANDSemu is a free, open-source Nintendo DS emulator for Android phones and tablets. It provides a streamlined graphical interface for running Nintendo DS games, with portrait stacked, landscape side-by-side and landscape stacked screen layouts, plus LCD swapping. Save states and cheat support are included. The project describes its code as based on nds4droid and DeSmuME, and also names DSdroid in the repository. ANDSemu is licensed under GPLv3; redistribution, forks and selling a fork require compliance with that licence, including source files and build scripts. The README recommends Google Play installation and gives source compilation as an alternative. However, AppBrain reports that the app was removed from Google Play on January 14, 2013. Its historical listing describes a free download requiring Android 2.3.3 or later. Source builds require ActionBarSherlock, Android Support Libraries and ndk-build for DeSmuME and other native libraries.

MindSpark is an open-source mind-mapping app that runs in a browser or can be self-hosted. Its editor combines an infinite canvas with automatic layouts, keyboard-first editing, drag-and-drop reordering, search, presentation mode, and undo and redo. A Markdown outline and the map canvas stay synchronized as users edit either view. Research tools can fill citation details from Crossref using a DOI and export cited nodes as a references list. Users can compile a map branch into a prompt, estimate its tokens, and run it with their own Anthropic or OpenAI API key. MindSpark imports JSON, OPML, Markdown, GitMind, and MindMeister files, and exports PNG, PDF, JSON, Markdown, Word, and Mermaid. Self-hosted mode stores maps in SQLite and requires Node.js 22 or later; browser mode saves maps as private JSON files in a repository on GitHub, Gitea, Forgejo, or GitLab. The app is free with no feature gates or usage limits and is released under the MIT license.
