Or you can use ROMripper from Remus package.
I made an archive with only the command and the readme which you can get here:
http://dl.dropbox.com/u/939939/ROMripper.lhaIf you put it for example on C: the only thing you need to do is open a CLI and run:
C:ROMripper RAM:MyKick.rom F8 512K
... and you're set
