CRC32
Calculating the CRC32 checksum for the ROM data of a UNIF file (NES)
shouldn't be done with ucon64_fcrc32(). nes_init() uses crc32().
The CRC32 checksum is used to search in the DAT files, but at the time
of this writing (Februari the 7th 2003) all DAT files contain checksums
of files in only one format. This matters for SNES and Genesis ROMs in
interleaved format and Nintendo 64 ROMs in non-interleaved format. The
corresponding initialization functions calculate the CRC32 checksum of
the data in the format of which the checksum is stored in the DAT
files. For these "problematic" files, their "real" checksum is stored
in ucon64.fcrc32.
