Attached are Kernal/VC Roms images that work but come up as unknown and/or doesn't accept them.

Do you know the names of the kernels? I don't know what to put into the database for them.

bluecursor commented 2 years ago

Do you need me to send them via email? The filenames are clearly marked what they are.

Not this time. Please use email next time.

I've added the Rom fingerprints for all Roms, but VC-1541_JiffyDOS.bin. This Rom is not recognized by VirtualC64 as a Rom at all. It must be some special patch, but I haven't been able to find out any details.

The "standard" JiffyDOS Roms are already supported:

   case 0xDE7F07008B787040: return KERNAL_64_JIFFY;
   case 0xA9D2AD1A4E5F782C: return KERNAL_SX64_JIFFY; 

   case 0x8B2A523E29BED889: return VC1541_II_JIFFY;
   case 0xF7F4D931219DBB5D: return VC1541_II_JIFFY_V600;

The particular Rom (VC-1541_JiffyDOS.bin) crashes the emulator. It seems to be a kernel Rom and might need a special drive Rom to work.
