How to use Amstrad CPC games in a Raspberry Pi (Reclabox or Retropie)?

Hi everybody...

My problem is this: when I try to use my Amstrad CPC ROM games in my Raspberry Pi 3 (which works with a Recalbox system), I don't know how to run the games... Simply appears the Basic 1.1 screen...

...I remember this screen when I had an Amstrad CPC 464+, 1992 perhaps... but although I type "run" command, the game don't works.
Anybody can explain me how I must do to use old Amstrad CPC games properly?.
Thanks to everybody!. :pwnd:
