+description = "A fork of the venerable Game Boy Advance emulator, VisualBoy Advance-Merged, branched off circa 2011, but with some backported patches for improved performance and compatibility. This core runs a bit faster than the up-to-date VBA-M core, but it is based on an older snapshot of the codebase and lacks many years of development and improvements, resulting in compatibility issues with some games (mostly related to a lack of support for the tilt and solar sensors). Most users should start with the up-to-date VBA-M core and only fall back to this one if they need the additional performance boost."

This core has known issues with a number of popular games, but it still represents the state of the art for open source Atari Jaguar emulation at the time of this writing. It is quite demanding but also includes a core option--Fast Blitter--that forces the use of an older, less compatible but faster blitter, though some games will not work properly with this option enabled."
