Common init code

I like your idea to make an MMC5 subset: it's more or less UNROM with banked PRG RAM but can be tested in any emulator with rudimentary support for MMC5 and NES 2.0. You may want to add two things: a canonical set of init code to get the MMC5 into a state where it acts like this mapper, and a caveat about writes to the RAM mirror at $1000-$1FFF. --Tepples (talk) 08:32, 11 August 2013 (MDT)
