The DS Browser doesn't support Flash, so no youtube

Still, it's not a bad bit of software, most webpages render really nicely on the dual screens, it's just not as fast as on a PC. Mind you, all the people that have been complaining about it being slow must be terribly impatient as I haven't had any problems with it.
I'm running it on my R4DS in Slot-1 with a Supercard Lite in Slot-2 - similar to motorollin's setup.
There are a few Amiga games on the DS these days - The New Zealand Story (quite a good port imo), Rainbow Islands (quite a bad port :-( ) Theme Park (an excellent port), Bubble Bobble (not bad), Sim City (a port of SC 3000, but still similar) and now Settlers. There could be more, but I can't remember now :-D There are lots of amazing original games on there too though - stuff like Phoenix Wright (I know it's a GBA port, but it never got released in English), Hotel Dusk Room 215, plus all the usual Nintendo stuff.
