SPRITE RIPPING ASSISTANCE: DOS GAMES!

So, this is a very simple request. As a guy whom used to play 100s of games during the 90s, I need to find a way to rip graphics from them, other then doing it bit by bit just out of screencaps. Basically, there is a game called "Blood and Magic", a DnD Rts from the 90s that I desire the graphics for my currant project.

I have already looked across the net, but if there are tutorials of how to rip graphics for DOS, or sprite sheets for the older DnD games that I admire the style from, I have clearly missed them. If you know how to do this, or at least a site that has some of the materials I am seeking, just tell me.

Try this http://www.shikadi.net/camoto/ I think it's still in development though, your best bet is look around here http://www.shikadi.net/moddingwiki/Category:File_Formats and understand how to open them with what. I remember messing around with dos graphic stuff awhile back but completely forgot the process.

edit: I just remembered, it had to do with WAD files, but those only apply to doom and doom clones. I probably don't know what I'm talking about as other games probably have a completely different way of storing graphics. Oh well just poke around.

Yes, this will help me a bit, but after poking around the folders, and sucessfully seperating the graphics from the code, in question, I believe I need something that can open, or convert a .gra file into a more standard file type...

Thanks for the links though!
