delta vs Hemulator

delta is a free, open-source pager for Git and related command-line output, including diffs, grep, ripgrep JSON, and blame. It can show diffs side by side with line numbers and automatic wrapping, and highlight edits within lines using a Levenshtein edit inference algorithm. Its syntax themes are the ones available with bat. Delta can be configured as Git’s pager and interactive diff filter, and its documentation covers zdiff3 for merge conflicts. It can highlight output from ripgrep, git grep, and grep; blame and diff hyperlinks can target GitHub, GitLab, SourceHut, and Codeberg. The manual also describes integrations with Magit, VS Code, tmux, and GNU Screen. Executables are offered for Linux glibc, Linux musl, macOS, and Windows, alongside package-manager installation instructions. Paging depends on less, for which the project recommends a reasonably recent version. The project includes the MIT License. The listed git-delta plan costs nothing.

Hemulator is a free, open-source emulator for classic gaming systems on Linux, macOS, and Windows. The project lists 17 systems, with support at different stages of development. It detects ROM formats and system types automatically, and gives users five save-state slots for each game. Display settings include software and OpenGL-accelerated CRT effects such as scanlines and phosphor filters; audio playback is integrated through rodio. Users can adjust controls, window dimensions, video backend, and display filters. Headless command-line tools provide debug dumps, instruction tracing, logging, and benchmarking. The documentation also describes using these tools in CI/CD for automated testing and repeatable regression checks. Windows and Linux packages are listed, including 32-bit and 64-bit builds and Debian packages. Users must supply their own legally obtained ROM files; Hemulator does not include or distribute copyrighted game data. NES emulation supports 14 mappers, so games that rely on unsupported mappers will not work. The project directs users to GitHub bug reports, feature requests, and Discussions for help.
