NoiES is an original NES emulator for the Nintendo Switch. Created entirely from scratch by Hydr8gon, it was developed as a means to enhance skills for future projects, NoiES surpassed expectations and evolved into a full-fledged emulator, apart from some minor inaccuracies and some missing mappers.

The homebrew was entered into the GBAtemp Switch Homebrew Bounty 2018 (Emulators, 3rd place).

Installation

Place the .nro to the /switch/ folder on the SD card.

User guide

Mappers

Each ROM is associate with a mapper, which is responsible for loading distinct sections of ROM memory into the CPU memory for execution. The most popular mappers as well as a few others have been implemented in NoiES (1-4, 7, 9, 15), which should cater to a large portion of the NES game library.

Minor inaccuracies

Aside from some 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.
