"Ultima Edition" is merely a proper "full install" of the game with a patched 1.02 .exe to include game fixes and no-cd. If you download the 1.02 exe update, patch it with the chocobo and mini-game fixes, you should be running fine. Just so I don't step on any toes, I won't include a how-to but I think any FFVII PC player should be converting their exe to a no-cd when finished as well, as the game's price just keeps rising and rising, and time passing inherently increases the risk of cumulating damage to the game disks. At the very least rip your disks and put them all onto a single DVD with a virtual drive program, or even copy onto separate CDs if need be.
