The existence of this specific BIOS has even been discussed in the emulation community. In one Baidu Tieba thread, a user detailed how their Batocera emulation system wouldn't accept a generic or renamed BIOS. After careful checksum verification, they identified the that worked was SCPH-90001_USA_Con_0230_20080220_v181_[7BA8763D].rom0 .
