zip0 Craig's Parallel Cyclic Redundancy Check

Craig's Parallel Cyclic Redundancy Check is a neat bit of code for the Commodore 64 that will give you the CRC value of a file on your floppy drive.  Just edit the F$ value on line 1 to match the name of the file on the disk you want the CRC for.

d64 floppy1 CRC32

CRC32 is an error checking program. When run, the program will ask for the name of a file. It will scan the file and report the "CCITT CRC-32" value. When transferring a program over a modem or with a copy program, you can run this program on that file before and after to make sure you got a 100% identical copy. Docs are on the disk. This program will work both on a c64 and c128.

This tools is along the lines of a crc32 check but uses it's own formula. Basically you run it on a disk, select the files you want checks for and it creates a file called "sacaid diskccheck" on the disk that you use to check the files after a transfer. The fastloader built into this tools doesn't work with VICE.
