RetroArch - Geolith

Geolith is a highly accurate core for a popular console/arcade system released in the early 1990s, and surviving into the mid 2000s. It is written in modern C and takes a unique approach compared to other emulators for this system. This core focuses on providing a user experience similar to a traditional home console, both by defaulting to home console mode and the use of single-file game files. However, despite this focus, it also maintains full support for playing games in arcade form.
