FFTPatcher won't allow any rare items from vanilla FFT in shops for some reason. If you open your patched ISO in FFTPatcher, you'll notice that no changes have been made to the shop inventories where rare items are concerned. I think you'll have to delve into the game's coding yourself, but I wouldn't even know where to start.
As for the 999 magic damage, did you happen to ASM hack anything? Perhaps you could open up FFTPatcher and take a screenshot of one of these abilities.
