hey can any one help. i downloaded ff3 from this site and a nes emulator but that emulator wouldnt work for sum reason.

then i found an old emulator on the computer, NESTCL95 which it appeared to work with. but after 3 mins it freezes. i can barely beat the first goblins before it freezes.

i know i,m not being very specific but any idea why an emulator would crash? the rest of the computer is sound. this computer has windows xp so maybe its not comptaible. if so, where can i get 1 that is? thanks alot.
