Kronos is a Sega Saturn emulator forked from uoYabause 0.5.2 for Linux and Windows. While this fork is accuracy-oriented and targets modern opengl, it tries to reconcile branches of Yabause and Yaba Sanshiro (formerly uoYabause) while implementing much needed fixes. Its compatibility and functionality arguably make it considered to be the best version of Yabause.
