Changelog from v1.4:

• Created a single “ef3usb.prg” and “ef3usb.exe” utility which includes all previous utilities in one single package.
• Speeded up the Turbo Reader a bit with reverse sector loading.
• Added 40 track support to D64 read and write (turbo version only!)
• Added turbo format command – 35 and 40 sectors. Curtesy of tlr’s “Format II” utility.

• “xfer” command added. This command will transfer (copy) files from the C64 to the PC! You can write these files in .PRG or .P00 format.
