+      ROMVER 0220JD20121227, the PS2 BIOS the PS3's ps2_emu carries. Cut from
+      dev_flash/ps2emu/ps2_emu.self of PS3 system software 4.90, decrypted by
+      RPCS3, from 0x12F bytes before "compatible mode" to 0x262 bytes after
+      "Parity error" and padded to 4 MiB, as firmware_bios_claim release 2
+      does. Accepted like any image with a valid romdir.
