DSVita vs MindSpark

DSVita is a free Nintendo DS emulator for PlayStation Vita, with an experimental Android port and a documented ARM Linux build. The maker says most games run, although some emulation features are incomplete. Two-dimensional rendering is mostly complete, while three-dimensional rendering is mostly implemented; missing effects and games using 3D on both screens can cause slowdowns or stutters. When ARM7 HLE fails, SoundHle or AccurateLle may be more compatible but slower. Release 0.9.4 lists savestates, Action Replay and libretro cheats, touchscreen controls and customizable control profiles. The rear touchpad can map to the DS touchscreen, and the right stick can control it. ROM files must use the .nds extension and be placed in ux0:data/dsvita. Vita installation requires libshacccg.suprx and kubridge.skprx 0.3.1 or later. Automatic frame skipping is always used, with no scanline rendering. The project recommends overclocking the Vita to 500MHz.

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.
