>More specifically you put games on an SD card and put the SD card in the flashcart. Similar deal for ODEs

Depends on the cart, some of the earlier/cheaper ones, or ones for very old systems, had to be flashed with a game and just directly booted into that one game with no menu. Changing games meant having to re-flash it. The latest example of something like that I can think of is the 3-in-1 GBA cart. While it was meant to be used as a companion to DS flashcarts on a DS, you could still flash a single GBA game to it with a DS and then play it on a GBA.

I guess one advantage of such a cart was that it appears as the actual game to anything you plug it into for anything that could link up with a GBA game, so you would for example be able to import pokemon from a GBA title to a DS one as if it was a real GBA Pokemon cart.
