It runs semi-badly. Soul Calibur is extremely well emulated, considering the overall completeness of the emulator itself. Complex 3D graphics take a whole friggin' lot of computer power to emulate smoothly. Be glad that Chankast renders all 3D stuff in hardware, unlike the Saturn which renders everything in software... Saturn emulation is even slower due to this, even though the two systems' specs are as far apart as day and night. Chankast needs to improve quite a bit. Even in many 2D games, the screen dimensions are off, sprite priority errors are plentiful and so are other graphical glitches. 3D games have depth errors and even worse transparency/alpha- and other errors. Even at that, Chankast is the only DC emulator that plays commercial games, with varying success. Sure, if we ever see a new Chankast version, we'll see speed improvements.
