OpenHomeKaraoke vs SMS

OpenHomeKaraoke is a free, open-source karaoke system for searching, downloading, and queueing songs at home. It can find songs on YouTube and download from YouTube and other video sites, including Youku and Bilibili. Playback supports MP3 and CDG files, including ZIP bundles. A DNN-based vocal splitter offers instrumental, vocal, or combined playback and requires PyTorch, preferably with GPU support; stereo track subtraction is also described. Voice search and queueing use OpenAI’s multilingual Whisper model. People on the same network can use a phone or computer browser to search the local library and add songs to a shared queue. Playback controls include pitch and tempo changes, seeking, and audio and subtitle delay. The display can be sent to a TV by HDMI or screen sharing, or viewed in a browser through an HTTP stream. Setup requires Python dependencies, VLC, and ffmpeg. Existing songs remain accessible offline, but internet search and new downloads do not. The project uses GPL-3.0, and its releases page lists no releases.

SMS is a free, open-source Sega Master System emulator written in Go for Linux. Its source repository is public on GitHub and described as MIT licensed. The emulator provides complete Zilog Z80 emulation and is described as concurrent. Graphics use an SDL backend with a 2x scaler and fullscreen support. Keyboard controls map the arrow keys to joypad directions, X to Fire 1, and Z to Fire 2. The README documents a Go installation command and shows launching an SMS ROM with the supplied executable. Sound support is listed as a project todo, and writing more tests is also listed as a todo. The stated free and open-source plan costs nothing. The project is focused on Sega Master System emulation, with the listed display and keyboard controls defining its documented user-facing operation.
