The Complex BIOS automatically bypasses region locking, allowing North American (NTSC), European (PAL), and Japanese (NTSC-J) games to boot seamlessly.
xemu allows you to increase the internal rendering resolution. While 4x or 8x looks incredibly sharp, scaling down to 2x resolution preserves the retro aesthetic while massively boosting performance on mid-range hardware.

The result is widely considered the best Xbox emulator available today, boasting more playable titles and better performance than its predecessors.
