C64 format floppies on amiga readable on a 1581?

[Dragster]

Hi mates!

 I have a software question here.. I'd like to get a 1581 3" 1/2 floppy drive for my commodore 64 in order to copy  software for the machine on my amiga and then read the floppies on the 1581 on the C64 and run the software downloaded from the internet (mainly games). I was wondering if there's a piece of software on amiga that lets me write 3 1/2 C64 format floppies readable on a C64 with a 1581 drive.

Any advise will be appreciated,

thanks!
