Dance dance revolution?!
 

I bought a copy of DDR for my pc. I got a no cd from game copy world. Unfortunately it has instructions I don't know what it wants me to do. It says "copy original_bin.dat file from the root directory of the cdrom". thanks for your assistance.

Insert the ddr cdrom, open it up in your browser, locate the file _"xxxb"in.dat, copy it to your installation directory of ddr.
