Enter – the only open-source, cross-platform original Xbox emulator capable of running commercial games with high accuracy. But unlike emulators for cartridge-based systems (like SNES or Genesis), Xbox emulation has a unique hurdle: the BIOS.
Some emulators (like Cxbx-Reloaded) use HLE (High Level Emulation) to bypass the BIOS entirely. Xemu chooses – executing the real BIOS code cycle-accurately. This is why Xemu is slower but more accurate.
Be a responsible member of the emulation community. Do not share your BIOS files. Dump your own, keep the hobby legal, and celebrate game preservation.

It will check the hash of your BIOS. If it is a bad dump (corrupted or modified by a modchip like an Xecuter 3), Xemu will crash. Therefore, if you acquire a file, you must verify its integrity.
