is megaman 9 an actual NES ROM being played as a virtual console thing, or is it just a Wii game with a *lot* of attention to detail re: NES limitations?
@Felthry the latter, there isn't a NES ROM to extract and run on a regular emulator
@Dex Makes sense, I guess. It sure looks like it'd be possible to play on NES though!
@Felthry A NES version was apparently planned at some point going by the Wikipedia article, but they'd have needed some way of getting the new engine running on NES and the game was still far too big for standard NES carts.
@Felthry @Tathar yeah at the time of MM9’s release, FPGAs weren’t at the point they are today, and it would have been ridiculously expensive.
Now you can have SNES games with CD audio via the SD2SNES IIRC, so I assume someone would be able to make it work for a NES game the size of MM9 if the need was there.
@Dex @Tathar A memory mapper is not itself a complex device, unless you want to add extra features to it like the MMC5 had for example
you basically just have to translate memory addresses quickly, which is easily accomplished on a CPLD or FPGA--and if you had to, could be done with a fast enough (where fast enough means ~100 MHz, maybe even less) microcontroller, too, though that'd be a little obnoxious to work with
