ClrMamePro calculates the crc32 of the full file. Goodtools skip possible headerinformation. So if you want to match the same files, you have to remove a possible header. Baddumps usually have to be padded with 0 bytes or truncated to some 2^x bank.

NES roms are different though. The require the header information but header information for each and the same rom can vary. The GoodNES datfile available at my page was not created on a direct database output from the goodnes.exe but on an existing collection. So you have to find the exact same roms with the exact same headers. Enjoy that ;)

The mentioned file is a baddump. Enjoy searching the correct memoryblock which matches the crc32. As mentioned...try padding with 0x00, try cutting of garbage (well..the full file is garbage) ...or simply stop collecting baddumps ;)
