Rominator lets you organize all of your DS roms with ease, view their information, trim them, or even transfer your legally backed up games straight onto your backup cart.
It is cross-platform, and the OS X version also allows Rom icon/header/game code/title editing, and also rom trimming (using safe-trim).
Transferring files is as easy as drag'n'drop and also allows backup of your DS savegames when you plug your card into the mac.

It is a Donationware program for members of (free to join).

Great app when it used to work, but unfortunately hasn't been updated since 2008 with the author having stopped all ongoing development.
As it is a PowerPC architecture app, the last version won't run at all since Apple stopped Rosetta support - so no PowerPC apps run natively since OS X Lion.
I am using Mountain Lion so have had to delete this app (yes, I could run it in a virtual environment using Snow Leopard but that's a hassle to set up - I just want something that runs "as is" on my OS).
An alternative which is also not actively being developed is RToolDS (last version released 2010) . ..but at least it runs on intel chips on Lion and Mountain Lion.

In Summary: Rominator was 5 stars when it worked, but it's now dead development wise with no intel version planned :(
