NoiES 1.2

NoiES for Switch

I present to you my own original NES emulator for the Switch, NoiES! This entire emulator was written from scratch by me. I started this project just to teach myself about how emulators are made so that I can work on larger projects in the future, but it went farther than I originally expected and is now pretty much a full-fledged emulator, apart from some minor inaccuracies and some missing mappers.

But there are already other NES emulators for the Switch, why use this one?
Well, no reason in particular. As I said before, this was more a learning experience for me, but I ported it to the Switch for the homebrew bounty and I might as well release it. I suppose the biggest advantage I can offer is that since I developed the entire emulator core myself I am very familiar with it and can easily dive in to fix bugs and add new features.

Minor inaccuracies?
Yes, well, aside from the missing mappers, it's mainly the audio stuff that needs work done. Most importantly the DMC audio channel, which isn't implemented at all. There are also a few minor inaccuracies in other places that shouldn't affect most things.

Right. Every ROM has a mapper; it's basically what loads different portions of the ROM memory into the CPU memory for execution. I've implemented the most popular mappers as well as a few others, which should cover a large portion of the NES library. If you have any particular games you want to play that aren't supported, tell me the mapper number (the emulator will tell you which one it is if it isn't supported) so I can place higher priority on implementing it.

Maybe you should add art boxes and title screen. And what changelog ? Thanks.
Ah sorry, I suppose there should be a changelog from the bounty release. Here you go:
-Mostly finished APU (audio) implementation
-Major PPU (graphics) fixes
-Substantial mapper optimization
-Added savestates
-Added settings menu and control remapping
-Various menu improvements

As for the game covers, it's not a huge deal for me personally, but if enough people want it I'll look into it eventually. Right now mappers are a higher priority for supporting more games!

    "earliest example of porn"
    An ivory statuette of a well-endowed woman discovered in Germany suggests that humanity's earliest art might have been of the erotic variety. Digging in a cave near Stuttgart last fall, University of Tübingen archaeologist Nicholas Conard unearthed what he says is the most ancient representation of a human female yet found--and, at more than 35,000 years old, one of the oldest sculptures ever discovered.
  • The Real Jdbye @ The Real Jdbye:
    but that isn't really porn, this might be the earliest actual porn
  • The Real Jdbye @ The Real Jdbye:
    and indeed, stone carving

    Did you just post porn?

    Yes but it mostly involves trying to get someone cancelled
