Emulation
Although I have not actually tried it, looking at the FCEUX source codes seems to not emulate PRG RAM in UNROM. There are some games that require it to be absent and some might require it present, this is a mess... you should fix FCEUX; if there are some games that require the absence of PRG RAM in some mappers, then for those mappers you could make it enable PRG RAM only if the battery bit is turned on, even if the game isn't actually using the battery; that seems the clearest way to do it without using NES 2.0. --Zzo38 (talk) 16:05, 25 June 2013 (MDT)
