:: I wonder if m210 is 'supposed' to represent the Namco175/340, with its simpler mirroring control (as described [http://d.hatena.ne.jp/na6ko/20110501 by naruko]). It's just close enough, and few enough games were released, that I could see how "fixed mirroring" or "correct default" might be good enough to make the games work. —[[User:Lidnariq|Lidnariq]] 12:04, 18 June 2012 (PDT)

Ok, so having looked over Naruko's notes and added them to the [[Namco 163]] description, my take is:
 
* Mapper 19 is Namcot 129/163, or an unseen variant of it without sound.
 
* Mapper 210 was originally for Namcot 175, which has hardwired mirroring, but has only one functionality conflict (register at $c000 becomes WRAM protect, but Naruko only mentions one game that has it), and so almost any game that used the Namcot 175 can probably actually be emulated safely using Mapper 19.
 
* No mapper was allocated for the Namcot 340, which uses the top bits of $e000 to select 1ScA/H/V/1ScB mirroring.
 
I think I can interpret Naruko's documentation to recommend that m210 be reallocated to the n340, and that the one n175-with-wram game be emulated as n340. —[[User:Lidnariq|Lidnariq]] 12:53, 24 June 2012 (PDT)
