Mapper 71 makes the game work in FCEUX all right, but breaks it in Nestopia. As the game writes to $8000 and there is no register at $8000 on real Mapper 071 boards, this is not Nestopia's fault.

It's the kind of thing that at this point in time will have absolutely no benefit, yet is the 'right' thing to do, so I would say 'yes', especially since I know of no emulator that is bothered by this.

(Background info: My custom Nintendulator Mapper DLL does honor the submapper field. If you were to set the submapper to 2, indicating the presence of bus conflicts, you would get the same result as in FCEUX. Which proves that the bus conflicts explanation was the correct explanation. There is at least one game (Cybernoid by Acclaim) that requires bus conflicts to be emulated, which is why emulating them is not just nitpicking.)

Famicom/NES / Nestopia Plus! R230 - Publicly Available!!!
« on: August 18, 2017, 04:20:06 PM »
Could someone please upload the current release (R348)?

I suppose one would have to register at that nesbbs website and download it as a message board attachment. Unfortunately, as I understand it, the message board requires two-factor authentification for registration, requiring the installation of a Chinese smartphone app, which is highly undesirable.

The reason FCEUX won't play it is that FCEUX always assumes bus conflicts, which original Nintendo UOROM boards suffer from, but the Kkachi board does not. One could use a NES 2.0 header and set the submapper to 1, indicating the absence of bus conflicts. Unfortunately, FCEUX ignores submappers, so doing this does not help either.

Famicom/NES dumps / Impossible/hard-to-run ROM images

ROM CRC32=032ae837, GoodNES 3.23b's "Street Fighter II - The World Warrior (Unl) [a3][!]". Starts with an unknown write to $6808, and has a bad NMI vector. If it weren't for the [!] tag, I would assume this was some kind of multicart rip.[/quote]It is definitely a multicart rip, as the end of PRG ROM still has menu code in it.

Nestopia Plus! runs it under Mapper 189. It does so by assuming that when bit 7 of the PRG bank register is set, the two 8K PRG banks at $8000 and $A000 do come from the MMC3; NESDev's Mapper 189 description says that the MMC3's PRG bank registers are always ignored. The title screen actually says "Master Fighter III" with a 1993 date credited to nobody.

It was originally from a 4-in-1 cart that had "Street Fighter III" (probably this one), "Home Alone 2", "Double Dragon 3" and "Alien" (?) on it. I haven't found such a multicart in my collection, but that may not mean much, since I don't collect multicart ROM images that diligently.

At the moment, it is only supported in Nintendulator with a custom mapper set.[/quote]Here is that custom mapper set, and attached is the updated source code for mapper 116 with added submapper support:
Code:
 
  Submapper 0: Huang-1, board config "P": most games unless specified otherwise
   Submapper 1: Huang-1, board config "W": Garou Densetsu Special (Gouder release), Somari (W version), Kart Fighter
   Submapper 2: Huang-2: AV Jiuji Majiang II (Gouder release)
   
   Note: Only Garou Densetsu Special (Gouder release) seems to really need "W" board behavior, in order to not crash at the end of a round.

That's a UNIF file that just has a .NES extension, not an actual .NES file. Here's an actual .NES format file of the game (cah4e3's UNIF format image converted to .NES):

Famicom/NES / Gouder versus Ge De
« on: August 16, 2017, 04:12:44 PM »
Maybe I'm being Captain Obvious here, but is Gouder Ltd. (of Street Fighter IV fame) just the anglicized name of Ge De Industry (哥德有限公同), or are they supposed to be separate companies?

Attached find Kazzo dumping scripts for mappers 115 and 116, verified by MLX to work.

Both Somaris do a strange write sequence at the beginning, which I am now replicating. That could be just a normal MMC1 serial register load, but that is usually done with one value and an LSR loop, not five unique 7-bit values. Of course, only the Somaris do this; the other Mapper 116 games just go straight into MMC3 mode, so I may be on to nothing at all. In any case, try this with Somari-P.

Both scripts returns were complete 0xFF with the Somari P cart.[/quote]That indicates that there is some kind of protection that is not replicated by emulators, and not described on the wiki page, because it isn't necessary to run the games once one is in possession of a ROM image. I can try some more, or you can tell me that you've had enough, and I'll stop. :) You could also ask CaH4e3 for dumping instructions.

As for Contra Fighter, it's listed on nesdev wiki and cites CaH4e3 as the source. [/quote]Then the existing dump must be from a different cart.

Famicom/NES dumps / KingPepe's Palace of ROMs
« on: August 16, 2017, 01:30:02 PM »
Thank-you, KingPepe.

Some emulators claim Mapper 136 support that however only works with one game: the Chinese version of Metal Fighter µ. Use this set of Mapper DLLs together with the latest "unstable" build of Nintendulator for full Mapper 136 support (source code), including the unhacked Chinese versions of Galactic Crusader and Mahjong Trap.

(Supposedly, Nestopia Plus! also has full support, although I have never been able to download that emulator because one apparently has to create an account with that bulletin board.)

AVJiu, a Somari (P config, which is 116), Contra Fighter [/quote]Wait: The Contra Fighter ROM I have uses Mapper 238. Do you assume that your Contra Fighter uses a different mapper?

Tested mapper 116 script with AVJiu, a Somari (P config, which is 116), Contra Fighter and it didn't work.[/quote]Then I have no idea.

It doesn't know Mapper 71 at all[/quote]Mapper 71 is basically an UxROM variant. Try the attached script, which is a modified UOROM script.

Maybe someone has a script for dumping mapper 116 games and we could make sure?)[/quote]As I understand the emulator sources, mapper 116 should be dumpable by the Mapper 4 script once you write value 0x01 to address 0x4100, which sets it into MMC3 mode. Try the attached script (untested).
