Xbox Questions

Hi all,

Been using Retrobat for a few years but recently decided to add some Xbox games. Went through the forums but couldn't find the answers I needed:

Does Retrobat have a built-in Xbox emulator or do I need to manually add one?
What format do the games need to be in? I currently have ISO and XISO, do they need to be concerted to XBE or something else?
Also, are any other files like MCPX or hard disk images required?

Thanks for any help!

Yeah, just setup xemu like you're using it by itself. All RB does is launch it for you, all your setting and such nonsense will be there.
