Cards like R4 allow you to store multiple games on one card. So when you start your DS, you choose which game you want to play and do not have to take all your games with you. The R4 relies on a microSD card to keep track of the games and save files. Your actual game, you should be able to recover from the original game cartridge (since you do actually own the game).

To recover your game progress (save file), you can put the microSD card in your PC (using the appropriate adapter) and just have a recovery program look for the files on the microSD card. There are several good FREE file recovery softwares on the internet. They will likely be your only shot a recovering your game progress but that depends on how much you've used your R4. If you have used it a lot, your save game may have been overwrite which means it is lost for good.

Whatever you do, do not do anything illegal.
