I might not be up to date with the status of Aroma, but last I heard, development has stalled, and it isn't compatible with most existing homebrew applications. Last I heard, it also doesn't run signature patches. In other words, Aroma is pretty useless for most users right now.
You're better off for now using Mocha (doesn't require a DS VC game) or Haxchi/CBHC. If you don't have a DS VC game for Haxchi/CBHC, you can install Indexiine and set things up so that Mocha CFW launches automatically when the internet browser is opened, even if you're offline.
