Crea una carpeta llamada ROMs dentro del directorio del emulador o en una ubicación separada.

Unfortunately, no GBA emulator for Xbox 360 supports link cable emulation. For that, you would need a PC emulator like mGBA.

For reference, your USB or HDD should look something like this:

Hdd1:\
├── Emulators\
│   └── RetroArch\
│       ├── RetroArch.xex
│       ├── cores\
│       │   └── mgba_libretro.xex
│       └── saves\
└── ROMs\
    └── GBA\
        ├── Pokemon_FireRed.gba
        └── Golden_Sun.gba

Enjoy your handheld classics on the big screen
