In their own words
DSperate
DSperate is a free, public-source Nintendo DS and DSi emulator for Linux on AArch64 and ARMhf. Its CPU emulation includes ARM946E-S and ARM7TDMI interpreters, plus ARM-to-AArch64 and ARM-to-ARMv7 recompilers. Graphics include complete 2D engines, a software 3D rasteriser and optional Vulkan GPU rendering. Experimental DSi support covers DSiWare, NAND boot, an SD card folder, microphone, Wi-Fi, PictoChat and Download Play, but the DSi DSP is not emulated and DSi-enhanced cartridges run as DS games in DSi mode. Local multiplayer and Download Play work over a LAN; internet access uses a user-mode TCP/IP stack. It has ten save-state slots and a hidden automatic slot, configurable screen layouts, cheats, and remappable keyboard and controller input with stylus support. Games can run with built-in FreeBIOS and generated firmware; user dumps allow firmware boot and exact timing. It loads .nds files and .zip files containing an .nds, but not zip64, 7z or rar. The project is licensed under GPLv3 and describes its implementation as clean-room work.
MindSpark
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.
