Ds Homebrew And Emulators

[Bramrash]

Hi all, the other day I bought myself a DS and R4 and was just wondering if anyone who's had a bit of experience with DS homebrew could tell me whats worth a go. Im already thinking of putting lemmings, scumm, doom, duke and maybe quake on it, but does anyone else have any more recommendations?

I've seen videos of a snes emulator that looks pretty decent (well, for the mario world/all stars at least) does anyone know the name of the best one?

Other emulator recommendations are also welcome.

Thanks, Dave
