I gave up emulating Dreamcast a long time ago, having rocked that console hard for years - it pains me to use emulators that, while amazing, were not quite up to par at the time. I have a similar situation going with the Amiga, I love that computer but have had horrible luck with emulators so I don't even try to emulate games, even though many I cover here make me REALLY want to fight configuring an emulator.
