help with downloading Fighting Vipers2

[safire25]

Hi guys, I have downloaded Fighting Vipers 2 and it gave me 85.rar files and when I extracted them with Winrar, it gave me nine .001, .002 etc files. From this point, I don't know how to get them to disc to put in my dreamcast. I have tried Winrar on these nine files and I can see the cdi file (there are 9 cdi files) but it says nothing to extract. I am very familiar with isos in general, but I am new to downloading straight from the internet. Any help on this would be greatly appreciated.
