So I just got an R4...
 

Anything I should do?
Donwloaded a resident evil theme. downloaded about 14 games... anything else in need of doing which is worth while?

what is a r4

Unless you havent already gotten the games make sure you get the Phoenix Wright games. I'd probably say get the ScummVM DS port and get the old Broken Sword/Monkey Island games on there. Get a few emulators, SNES, Mega Drive/Genesis that sort of thing. Check around and see what good homebrew Applications and games there are too.

Cartridge for the DS which allows you to play Homebrew Games & Applications, along with Backed up copies of games. It's essentially a DS Cartidge which allows you to put a SD Memory Card inside and the DS can access the card. They're supposed to be really good I'm after one myself.

that sounds like a pretty nifty tool
