It merely turns on and off re-reading of the tracks written in first pass and trivial checksum comparison.

Marko already mostly answered the question about what's so great ;-) The fastest d64 creation tool I've heard of supposedly does it in about 20 seconds with the pc assistance and its thousands of times more powerful CPU. The fastest pc-less tool I've seen claims to do it in 25 to 30 seconds but I never managed to get a single reliable copy out of it. Oh, and BTW. I did hear of "15 seconds copy"... a lot of my tool's code is based on its concepts! ;-) -- If you are using a new Macintosh running OS X then you probably have [...] "daemons" (programs that hide in the background, doing things without the user's notice) on your computer [...]! This clearly illustrates that not only is Macintosh based on Darwinism, but Darwinism is based on Satanism. - Dr. Richard Paley Message was sent through the cbm-hackers mailing list
