Soul Calibur 2 is not HD Loader/Advance compatible. Check http://homepage.ntlworld.com/casey.miller/HD Loader Compatibility.htm for more information.
Thanks for all your help, i have one more question, when i try to convert a game into my hd it say "bad cd" can some one tell me what is it?
First, check that compatibility list again to see if that game has a known problem installing. Next, check the disc for scratches or any other damage. From my experience, HD Loader/Advance is extremely sensitive to any disc damage. If it's a backup disc you are trying to install, try re-copying it and see if that works.
