For the most stable emulation experience, Xemu developers and community members recommend using rather than strict, unedited retail dumps. Modified BIOS files bypass early hardware initialization checks that are unnecessary or problematic in an emulated environment. The most widely supported BIOS versions for Xemu include: Complex 4627 Xecuter2 (e.g., X2 4981 or X2 5035) iND-BIOS (e.g., iND-BIOS 5003) EvoX M8+ When setting up Xemu, you will encounter two
