I'm not aware personally, but has anyone so far taken all known NES/Famicom dumps and scanned for which entries are UNIF? We could go about the process as a community to start assigning NES2 mappers and submappers for them.

It's best that the community with the most "know how" goes about collectively assigning mapper numbers (submapper numbers) who are actively writing emulators. :)

Involving ROMs, we could easily just create archive.org accounts and get our work done through safe harbor.

The following UNIF boards have been defined by FCEUX as iNES Mapper numbers:
Code:
60   BMC-D1038
90   UNL-TEK90
123   UNL-H2288
125   UNL-LH32
176   BMC-FK23C
220   UNL-KS7057
221   BMC-N625092
226   BMC-42in1ResetSwitch
238   UNL-603-5052
256   UNL-DANCE/UNL-OneBus
257   PEC-586
258   UNL-158B
259   BMC-F-15

I could immediately post Nintendulator Mapper DLL sources and descriptions for the following boards, for which I have tentatively assigned so-far unused mapper numbers:
Code:
260     BMC-NTD-03      Asder 20-in-1
261     BMC-11160       Micro Genius 6-in-1 Cartridge (MGC-023)
262     UNL-SHERO       Street Heroes/侍魂 (Shìhún, by Sachen)
263     UNL-KOF97       Boogerman II, King of Fighters '97 (by Rex Soft)
264     UNL-YOKO        Mortal Kombat II, Master Fighter VI' (by Yoko)
265     UNL-VRC7        Yoko fighting games with copyright removed
266     UNL-CITYFIGHT   City Fighter IV
512     (no UNIF board) 中國大亨 (Zhōngguó Dàhēng, a.k.a. "Millionaire II", incorrectly labelled "Chuugoku Taitei", by Sachen)
513     UNL-SA-9602B    美少女 夢工場三 (Měishàonǚ Mènggōngchǎng 3, a.k.a. "Princess Maker", by Sachen)

The following are other UNIF board names for which I have dumps, but so far not taken a closer look at:
Code:
UNL-EDU2000
UNL-Transformer
UNL-RT-01
UNL-EH8813A
UNL-MALISB
UNL-DRAGONFIGHTER
UNL-43272
UNL-DANCE2000
UNL-KS7013B
UNL-KS7016
UNL-KS7017
UNL-KS7037
UNL-AC08
UNL-BB
UNL-SMB2J
BMC-12-IN-1
BMC-411120-C
BMC-64in1NoRepeat
BMC-70in1
BMC-70in1B
BMC-810544-C-A1
BMC-8157
BMC-830118C
BMC-8-IN-1
BMC-A65AS
BMC-BS-5
BMC-FK23CA
BMC-G-146
BMC-HP898F
BMC-T-262
COOLBOY
DREAMTECH01
UNL-8237A
There are probably many others, in particular multicarts. I have also been working on a very simple UNF2NES converter that uses the above tentative mapper numbers (attached).

Very nice work! Of any of these, like City Fighter IV, would many of them be able to be assigned as submappers with "mother mappers"?

The City Fighter IV mapper is completely different from Mapper 189, used on Street Fighter II and its name hack Master Fighter II. Mappers 262, 263, 512 and 513 are MMC3 clones with enhancements, which so far have always had unique mapper numbers. 260 and 261 are simple latch-based mappers, probably using discrete chips. I haven't looked at the FCEUX ones and the long third list at all.

The only submapper candidate I see would be "UNL-YOKO" (264), which could be seen as a Cony submapper 3 (2 KB CHR ROM banks, but different than submapper 1).

I thought we were going to put newly discovered Asian games in 512-767 or something, to minimize trace conditions between the scene dumping uncommon Asian games and the homebrew development scene.

"Plane 1 (NES 2.0 mappers 256-511) is reserved for mappers used by games released outside the East Asian market". Which of the 260-266 mapper games do you know were solely released in the East Asian Market, which would justify putting them into the 512+ region?
