Well, time to freshen up this dusty board with some news I guess...
A few days ago, out of nowhere a new emulator was born, that currently is being totally hyped in the emulation scene. The dreamcast emulator Chankast seems to run quite a bunch of games in decent speed, I can't really tell you any details though, as I don't exactly know whcih DC-games I really want to play... I don't wanna diss the system, but I always thought there was a reason for it's failure... all the interessting games I wanted to play were ported to other systems later on, I'll make a list for you, maybe you want to check some of them out!
Good DC-Games I already played somewhere else:
Resident Evil: Code Veronica, Skies of Arcadia (quite nice RPG), Sonic Adventure
So here a list of games I actually want to try on the emu some day when I have found them:
Shenmue 1 + 2 (THE DC-games, seem to be true classics, what i saw of them seemed fun, not working yet), Sonic Adventure 2 (I'm quite sure this one blows though, working), Ikaruga (innovative shootemup, working), Powerstone(fun beatemup, working), Jet Grind Radio (working), Soul Calibur (classic beatemup, doubt id like it though, not working), Samba De Amigo (some stupid music-game, but apparantly a classic, working)
anyway, grab the emulator here:

any experiences welcome, once i got the time/ressources to make my own I'll post them here!
