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.

Great! Do you have the PCBs of these particular game/title screen variants? These are the variants that still need to be studied, because they have some unique protection features.

Enforcing such requirements consists of an insensitivity in and of itself, as doing so imposes the highly idiosyncratic moral tastes of progressive Anglo-Saxons on the rest of the world.

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

Thank you, krz. A couple of points: Which bit is output to pin 27? The pin description says $5000.6, but the register $5000 description implies $5000.4. The "open bus" setting comes from the Dongda Pyramid Educational Computer PEC-9588, on which this chipset was originally used, where it selects bet...

It has been dumped already, has a mapper (#555) assigned for it, and is in the NES 2.0 XML Header Database. It will be the dumper's decision whether or when the dump will be released.

I can see that I will have to rewrite the wiki pages for mappers 162-164+558 many times to come.

There are still four more boards using this mapper blob, probably all with strange little wiring variants.

You mean $5300.1=1

That is the dump I got with $5300=$07, not $04.

Thank you. Comments: CPU A8 and CPU A9 must be swapped compared to mapper 163 as well, to make the Microwire interface appear at $5200 instead of mapper 163's $5100. * What exactly do bits 4-6 of register $5000 do? Those data pins are not wired so they don't matter Them being set by the game must be...

Now we can seriously ask, which games did not get the DPCM bits in reverse order ?

Nintendo's own games.

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