I was traveling for a while and forgot my Nintendo DS, so I started playing on an emulator. During this time I played Pokemon Black 2.
I've grown particularly fond of my team. I now am back home but with a Pokemon save file on OpenEmu for Mac. I have a copy of Black 2 (as in physical cartridge) and am wondering if there's any way I can transfer my Pokemon over from Black 2 ROM to Black 2 legit cartridge.
My eventual goal would be to bring these Pokémon into X and Y.

Yes you can. However you need some special hardware.
First you need a Flashcart. A flash cart is an special cartridge which allows the use of homebrew in the DS. Homebrew software is software developed by the community to be used on certain device or environment. This homebrew usually comes in the form of roms or similar.
With that said, you can use such a Flashcart to load a .rom into it, and then use your DS with that cartridge to launch the .rom. Now given that you already have a save file you want to transfer, you need to copy the save file to the Flashcart too, these files are usually placed besides the rom, by the respective emulator.
Now, following this process you cannot transfer the pokemon between your Flashcart and the X and Y games, because of some security measures implemented by Nintendo. So you need to transfer them to a previous generation game first. Which is great given that you do have the Black cartridge.
So, to transfer the pokemon between the two Black versions you need two DS with the respective cartridges, and use the Union Room to transfer the pokemon.
Once you got your pokemon into the real cartridge, you can transfer them to X and Y using Pokemon Bank.
Note: I have not done the process myself, but some time ago, I was thinking about getting X and Y, and looked up about the transfer possibilities. And i read some tutorials explaining what I stated above.
Couple ways I can think of.
- Utilizing an ActionReplay system to turn the Pokémon to code, and then transfer them to ActionReplay in your physical game
- Using a Flash cart to import your whole save file in the emulator to a new physical cartridge
- Use Pokegen to recreate your team manually. You'll need to know all the pertinent data, though, like secret ID and actual regions.

Unless you have something like this and all the set of software that it requires, you won't be able to move the save game across to the cartridge:

This 'toaster' is used to develop NDS games and can write on cartridge memory.
I would suggest to support game companies by purchasing their games and not using emulators; game developers spend a lot of time and energy to bring you good games, they should be rewarded :)
I don't know if Nintendo DS systems have a Micro SD slot, but I would put the game info on the Micro SD card and put that card in the DS. That way probably doesn't exist so the more difficult but realistic way would be to put the ROM stuff onto a Micro SD card, and then put that card into a special USB thing that reads stuff from Micro SD cards, and then put that into a computer, and then take your 3DS or DS SD card and put that into the computer, and then move the ROM stuff from the Micro SD through the computer and into the DS or 3DS SD card. Take the 3DS or DS SD card put it back in your DS and hopefully you can take out the Pokémon from the ROM black 2 and put it in the Pokémon bank and put them in the real black 2.
