identification of BIOS image files

huexpress searches for the following files in the filesystem:

DD Checking for CD syscard at : /usr/share/huexpress/syscardsyscard.pce
DD Checking for CD syscard at : /usr/share/huexpress/syscardsyscard3.pce
DD Checking for CD syscard at : /usr/share/huexpress/syscardsyscard30.pce
DD Checking for CD syscard at : /usr/share/huexpress/syscardcd-rom~1.pce

(yes, that's actually what it prints. there's likely a bug and this should be /usr/share/huexpress/syscard/xxx.pce)

so there are 4 bios rom files with no identification other than some DOS-era short file name. i've only been able to get a hold of "syscard3.pce" via a websearch (and a syscard1.pce which i suppose is syscard.pce) to compare it's CRC against the list in romdb.c:

{0x3F9F95A4, "[BIOS] CD-ROM System (v1.0)", "NEC", __ID, __DATE, JAP | CD_SYSTEM},
{0x52520BC6, "[BIOS] CD-ROM System (v2.0)", "NEC", __ID, __DATE, JAP | CD_SYSTEM},
{0x283B74E0, "[BIOS] CD-ROM System (v2.1)", "NEC", __ID, __DATE, JAP | CD_SYSTEM},
{0x51A12D90, "[BIOS] Games Express CD Card", "Games Express", __ID, __DATE, JAP | CD_SYSTEM},
{0x6D9A73EF, "[BIOS] Super CD-ROM System (v3.0)", "NEC", "PCE-SC1", __DATE, JAP | CD_SYSTEM},
{0x2B5B75FE, "[BIOS] TurboGrafx CD Super System Card (v3.0)", "NEC", __ID, __DATE, USA | CD_SYSTEM},
{0xFF2A5EC3, "[BIOS] TurboGrafx CD System Card (v2.0)", "NEC", __ID, __DATE, USA | CD_SYSTEM},

so from what i've gathered via random web downloads is the following corresponding CRCs: (output from hucrc tool, where available)

syscard.pce; CRC=3f9f95a4; [BIOS] CD-ROM System (v1.0)
syscard3.pce; CRC=6d9a73ef; [BIOS] Super CD-ROM System (v3.0)
syscard30.pce - unknown
cd-rom~1.pce - unknown

if anyone can confirm this list and fill in the blanks, this would be most helpful.
