| Compatibility-wise...I wouldn't really know...but it'd probably be around the lines of FCE Ultra, I would think. | |||

I'm only vaguely sure what you're talking about, but I can assume the answer is likely FCEU.  |

Each NES game uses a different mapper. Some use mapper 0 (no mapper?) like the old Nintendo games, but every game has their own mapper. Some correspond to chips (MMC-1, MMC-5) but others are just off the charts.  |

| Probably NEStopia, as it supports 137 mappers. FCEU supports something like 129. | |||

| Not every game uses a different one. A mapper is basically a memory bank controller, for accessing more memory than the NES can access directly. (IIRC, cartridge ROM is mapped somewhere at like 8000-FFFF, this only gives you 32K. A bigger ROM needs to use a memory bank contoller to swap in different parts of the data to those addresses. Say it's set to bank 3, that means when it tries to access $8123 it really gets $8123+($8000x3).) It also controls things like mirroring, saved games, etc. Many games use the same chips, in particular most of Nintendo's, but then there's a lot of third-party and even moreso pirate games that have come up with their own crazy concotions, each of which needs to be emulated a different way. (Sorry if I'm wrong about any of this, I'm not really an NES expert.  ) |

Oh, but that's what I meant.  Every game uses a different mapper - you can't just take 10 games and think that they all use the MMC-1 (Mapper 1) chip. Then again, some mappers are rare and are only used for pirate games or rare Japanese games, and those aren't exactly priorities when building an emulator from the ground up. |
