I've seen on other groups that you have overclocked your EM500. I was wondering if you have seen any appreciable speed differences in using various emulators. I have been fairly happy with the speed of Mameboy, but other emulators (ComeBack64, and the NES emulators in particular) are just too slow to be of any real use to me. I have thought about taking my EM500 to 180 MHz, but I don't want to risk damaging the unit if the speed increase is negligable.
