Technically bootlegs should play the same as a real cart if they were manufactured right, but of course, most of them weren't. Usually glitches and sound errors ocurr due to bad rom dumps. eproms are not a definite way to tell if they are a boot, because many official carts have a few in them. Look for Flash MX chips and chips made in singapore (Singapore chips are also usually very scratched up for some reason). The other dead give away is sloppy hand soldering.
