Dissidia NT Region Lock and Code Giveaway

Out of curiosity, does anyone know if the servers for the beta are region locked or not? For example, are people who register for NA limited to playing with NA players? I'm currently living in Japan and play the arcade version pretty regularly, but I'd like to give the closed beta a try since I was gifted a large number of NA/EU (seems to work for both sites) closed beta codes.

For those who want an NA/EU closed beta code, PM me! I have 24 remaining as of now! Also, anyone with questions with how the game works, feel free to ask as well!

Update: 5 Left

Update 2: I'm out of codes! Good luck to you all!
