The 6693BD20 PRG ROM has been moved into the Bad Dumps category, because it had a few bytes in a long FF section replaced with garbage.

The directory names in the XML comments are subjective commentary and not part of the database content proper.

That being said, so far there has been no evidence of the reproduction ROM content being modified in any way.

I have added mapper 4 submapper 5 per my indicated intention. For nes20db, this deprecates the scrambled mapper 249 dumps, and makes the unscrambeld dumps, denoted as mapper 4 submapper 5, the "good" dumps, allowing them to run in emulators that do not emulate the address scrambling at all...

I have corrected that omission on the wiki.

That is nice, though a bit superfluous, as an official PRG1 revision of the game has since been found and included in No-Intro that no longer has this requirement.

(Edit: spelling error corrected)

All right. So the only remaining question is: is it even worth allocating a submapper (5 would be the next) for mapper 4 just to denote the 43-319 PCB that powers on with scrambling enabled, even as the games immediately write to disable it?

And here are the complete PRG and CHR scrambling patterns for all eight $5000 values. As before, I assume that $5000=$02 is the unscrambled bank order. Assume a different value as being the unscrambled bank order only requires resorting the rows in each table. For PRG banks, only $5000.0-1 are consi...

Since lidnariq indicated that D2 is also connected to the mystery blob, I checked and found out that there are eight, not just four, scrambling patterns, all selected via $5000. Only one seems to have ever been used by any known game though.

Yes, I can look at FCEUX source code myself. I think I would want to do the following: preserve mapper 249 ROM files as legacy dumps, but consider the 5000=02 bank order as the true unscrambled bank order, for the reasons stated above, and define the "good" dumps as mapper 4 with a new sub...

We finally obtained a circuit board of Mapper 249 , used on original Waixing games from 1996. It is basically TKROM/TLROM but with an additional register at $5000 taking values from 0-3 that select one of three patterns in which the PRG and CHR ROM address lines are scrambled. I am focusing only on ...

Yes, you have the 72-pin version, I have the 60-pin version.

The PRG ROM content is identical to my dump. The correct NES 2.0 header is:The full title on my cartridge label is "1992 劃面選關 1050-in-1".

Finished dumping the 1050-in-1, along with a 400-in-1 using the same mapper 354. I have updated the wiki article accordingly. The ROM image file will be released in a more appropriate place early next year. If you need the file earlier than that, you can always run my script with your own cartridge....

I did not look at pictures depicting any links between chips; I was merely debugging the menu code to produce my modified script. You keep asking 500,000 questions instead of just trying the script again.
