Because the BIOS is Japanese, it natively boots Japanese games without needing region-patching patches or cheats. While many modern emulators can bypass region checks, using the native BIOS reduces emulation overhead, leading to a smoother experience. 3. Essential for Emulator Accuracy

This is rarely a BIOS issue and usually a CPU bottleneck. The Saturn's dual-core architecture is notoriously difficult to emulate. If your hardware is struggling, try switching from the hyper-accurate Beetle Saturn core to the more performance-friendly Kronos or Yaba Sanshiro cores.
