Upgrade from V4 to V5

Hi. Is there a custom version of V5 Retrobat? Because the one I downloaded it is the full one with no options and I don't want to install all the emulators.
I have installed the V4, if I update from this one am I going to download everything?

Thanks.

Hello
Actually if you download the V5 from the Retrobat website, you will get an installer that will place on your Retrobat folder all necessary files, but without emulators.
Emulators will be downloaded from our servers when you try to play a game that requires it, and when you start the emulator from the Retrobat system menu.

Thank you!
