Talk:NES 2.0 submappers

I like this. I have written some ideas relating to this (as a user subpage) but your article is much better, but incomplete so we can improve it. --Zzo38 14:39, 23 September 2012 (MDT)

iNES Mapper 078

My point, although poorly represented, is that no existing game needs mapper 78 to support hard-wired mirroring. It is not necessary for original games, and it is not necessary for homebrew: User:Lidnariq/Discrete Logic Table shows that mappers 70 and 72 are equally capable. Thus there is no reason to allocate a submapper. —Lidnariq (talk) 12:14, 6 April 2013 (MDT)

MMC5

Should there perhaps be MMC5 submapper for CL and SL mode? (See also my comment on the MMC5 pinout) If there are significant differences between MMC5 and MMC5B (it says they are unknown; I am guessing there aren't any significant differences), should there also be submapper codes for this? --Zzo38 (talk) 14:11, 28 April 2013 (MDT)

No games were known released in CL mode. For the most part, I'm trying to not allocate a submapper until I can both describe the differences and describe a need for it. ... which makes me have second thoughts about the CNROM allocation; if the game cares about those diodes it'd be m185. —Lidnariq (talk) 14:27, 28 April 2013 (MDT)

Well, the mapper does support CL, even if no existing games use it; it means that a homebrew game can use CL if it ever seems useful for whatever arcane reason (even CL games would probably work fine with SL though, but maybe CL would have other effects; I don't know if it would scroll only the colors or what). --Zzo38 (talk) 18:34, 28 April 2013 (MDT)
