adding 2nd board to arduino platform

[Reefology]

Hi,

wanted to play around with programming so I bought a mega board. the problem I'm having is the platform won't allow me to select a regular arduino board, I can only choose RA or RA+ under Tools/Boards. Do I have to download another platform? if I use this one, will it mess up my libraries or folders for the RA?

any advise would be helpful.

thanks

Use RA+
