Mapping the same control to two different controller buttons

Hi

I have everything working perfectly, RetroArch is such a great idea. I am using the windows version with an xbox 360 controller

Is it possible to map a button more than once, e.g. map the Mario jump button to both Y and A on an xbox controller, or in some games where a and b need to pressed at the same time, map them to a single button as well as individually?

Also is it possible to have RetroArch auto detect a core from the command line?

Many Thanks in (Game Boy) Advance.

AFAIK, the answer to all of these is no. Core detect is a function of RGUI, IIRC, and the multiple mapping stuff is avoided for complexity reasons. You can, however, use an external program like AutoHotkey to make your own macro key that enters both values.
