Xbox Games on Nintendo DSi: Not Compatible

Impossible. Fundamental mismatches:

• Hardware: Xbox (x86 CPU, NV2A GPU, 64MB RAM) vs DSi (ARM9/ARM7, 16MB RAM, no GPU).
• OS: Xbox Dashboard vs Nintendo proprietary OS.
• Media: Xbox = DVD/Digital; DSi = Cartridge / DSiWare (SD).
• Binary Format: Xbox .xbe vs DSi .nds/.dsi – zero compatibility.

No emulator, port, or adapter bridges this gap. Play Xbox games on Xbox; DSi games on DSi/3DS.
