Use GRF tools, which can be found here:

If I'm not wrong, those downloads already come extracted[no zip/rar/uhn/7zip/etc file extension].
grf is the final format of the files, no need to extract them, just put them in the same folder as the other extracted files.

ro10012012_data.grf.part01.rar

Make sure all parts are in the same folder. Then just open part 1 and extract it, automatically part 1-8 will be extracted and you can install the game.

I thought the instructions are included with a link to rar or 7zip.  Anyway, to extract these rar files.  You need one of the extract program:

7zip: http://www.7-zip.org/
OR
winrar: http://www.rarlab.com/download.htm

and follow how xyuki described it above me.
