Emu198x vs OpenHomeKaraoke

Emu198x is a free, open-source emulator suite for running vintage computers and consoles through JSON scripts or an MCP client. Its registry lists 30 machines, with boot captures available for 29. Scripts can automate actions such as advancing frames, querying a CPU register, and saving a screenshot; documentation also describes capturing frame sequences and audio. Each machine binary can act as an MCP server, exposing tools to run frames, inspect state, handle input, and capture output. Clients connect over standard input and output using JSON-RPC. The maker says repeating a script produces an identical report and byte-for-byte matching screenshot. Release archives are provided for Windows, Linux, and macOS, including separate Apple silicon and Intel Mac builds. Emu198x does not supply commercial ROMs, firmware, disks, tapes, or cartridges, so users must provide required files. The accuracy page reports crate counts and boot-capture status rather than percentages or maturity scores, and SHA-256 sums are available to check downloads.

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.
