No corruption, no missing bytes, no header modifications. This is the original 512KB (524,288 bytes) dump. Use these values to verify your file: |

| Problem | Likely Cause | Solution | |---------|--------------|----------| | Emulator ignores BIOS | Wrong folder or filename | Move file to /system/ (RetroArch) or rename to exact expected case. | | Games hang on black screen | Corrupted BIOS or wrong version | Re-dump or re-verify checksum. Use 2048-byte dump. | | "SEGA" logo appears but game crashes | Cartridge header checksum mismatch (normal for homebrew) | Disable "Require Valid Checksum" in emulator options. | | Emulator requests bios_SEGA_100.bin | Different BIOS version | Some very early consoles used v1.00 (still 2048 bytes but different checksum). Renaming bios_SEGA_101.bin to bios_SEGA_100.bin often works. | ✅ Status: sega101
