That's an FCEUX-specific problem. I will not change the database entry for that.

That is the method Nintendo used to verify the file integrity of ROMs at its factory and included the sum16 values in its spreadsheet inventorying the Famicom and NES ROMs going through its assembly line. This spreadsheet does not include Japanese games from third parties like Konami and Namco which often or always made their own cartridges as well as unlicensed games. The sum16 method does not appear to have been used in ROM integrity checks for games for other Nintendo consoles.

Just a few more questions,
Duck (Asia) (En) (Unl) it's listed as Vs-UniSystem but I couldn't find it here: https://nintendo.fandom.com/wiki/Nintendo_VS._System, I'm wonder if has some special VS features.

About U-Force Power Games, those are using the pcb NES-GN-ROM, shouldn't those be listed as mapper 66?

Probably a shortcoming in whatever tool you're using to inspect the headers after the fact. I assume you're talking about this entry in nes20db.xml:

Code: Select all

        <game><!-- Unlicensed Taiwan&amp;Hong Kong\Duck - 醜小鴨.nes -->
                <prgrom size="32768" crc32="18663A40" sha1="6365BAA8D31149AF2D99462F17982551F968E932" sum16="3188" />
                <chrrom size="8192" crc32="33497EA7" sha1="BCFDFB43A8BC929AC2805FEA17A7BB0412B46E6B" sum16="8432" />
                <rom size="40960" crc32="0FAFC70B" sha1="686DDE8A8D6DAE037A3E34CEDB30FA5C3BB4B9DD" />
                <pcb mapper="0" submapper="0" mirroring="H" battery="0" />
                <console type="3" region="2" />
                <expansion type="1" />
        </game>
which is "Famiclone with functioning decimal mode".
NES2.0 defines setting both the "Vs. System" and "PlayChoice10" bits as meaning "look at the other table"

If other sources list it as GNROM, then suppose I should believe them and set it to mapper 66. The game only has 32 KiB of PRG-ROM however, so GNROM effectively is reduced to CNROM functionality. So it makes no difference in the end.

Updated. Apart from small additions and corrections, added the Hacker International redumps, and corrected the mapper 558 files' bank order based on recent analysis of the PCB -- which in the case of the Waixing games makes the old dumps "good" again.
