Games with better graphics are probably harder to emulate as they probably make use of more functions that need to be emulated, which means more work for the processor in your computer, and therefore lower performance. I would guess that KH 1,5 also makes use of currently unfinished things like cellSpurs (crap that is part of the PS3) and therefore it would probably not run at all, but you can always try.
