Never rename other BIOS files to dc awbios.zip . The emulator checks for specific internal hashes. If the CRC32 values do not match what the emulator expects, it will reject the file.
If you cannot find or create a legitimate dc awbios.zip , you have two alternatives:
docs/docs/library/flycast.md at master · libretro/docs - GitHub
: If the emulator reports a CRC error, the BIOS file is likely corrupted or from an outdated set. You will need to source a BIOS verified for the specific version of the emulator you are using.
