Flashcart Recomendation

Hello, I have been wanting to buy a flashcart, especifically the DSTWO. And I have a few questions for people who own the card. I currently own a DSi with version 1.4.4U I believe.- Will my DS support the flashcart?
- Does this flashcart run Pokemon Black/White 2 (English Patched)
- Can I transfer my saves from my computer (using Desmume) onto the flashcart and continue my game on my DS?Thank you in advance. :)

Yes.
Yes.
Yes, though, you may need to convert the saves, though, I think just renaming them works for DeSmuME saves.

Thank you so much for your answers, really appreciate them. :D

About that converting what save file desmuds of how it is called uses?
