It would be great to see CCS64 incorporate true NTSC emulation as seen and demonstrated here with Blargg's NTSC Libraries:

The author apparently even has a Commodore 64 ready library for implementation per the homepage.
Other cycle based accurate emulators have incorporated it such as Nestopia emulating the NES and bsnes for SNES. Atari 5200 emulator kat5200 uses it as well. It would be fantastic for NTSC users to have this an option as a Video display.
