CCS64 is really outdated, especially the SID emulation and video rendering. Vice and Micro64 are the best atm, and maybe Hoxs64 (not that many extra options, but a great compatibility.) CCS64 is good for slower PCs. If want accuracy you should use the others, though you need a modern PC for them. Not a 5-6 years old machine.
