Even better (if you use Photoshop) is the Minolta Raw (MRW) Photoshop plugin. You can download it directly from this link.
Put the mrw.8bi
file in your "photoshop/plugins/file format" folder. You will now be able to open *.mrw files in Photoshop! There are a couple of pre-processing options, but you don't have to use them.
Thanks to jean6 for originally posting this link. I'm reposting the info to this thread so that more people will see it.
