NESDL

A NES emulator written in C++ and SDL2. Just a fun project to see if I could make one, nothing more! Made for Mac and PC, but a Linux build should be possible as well.

Note: this is EARLY in development! It is missing several features, such as:

(most importantly) NROM titles ONLY! That means only NTSC (US) titles from this list work.
Player 2 (the logic is in place, but no keybinds yet)
Non-standard controller support (eg. Zapper, Power Pad, and so on)
Rebindable controls
Save/load states
Cartridge save data (eg. Excitebike stages, Kirby's Adventure progress, etc.)
PAL region support

Controls

Currently, controls are hard-bound to the keyboard (mainly for me to use while development is under-way):

D-Pad - WASD
A - N
B - M
SELECT - Comma (,)
START - Period (.)

To-Do

Each action item is checkmarked to show progress (Updated 10/7/2024)

General/Misc

Basic APU support (audio)
Configuration file
- Store Player 1/2 controls
- Store audio level
Save/load state support
- Could it be cross-emulator supported - FCEUX/Nintendulator/NESTopia loads our save state? Is there an agreed-upon standard here?
Rebindable keys menu
- May be more difficult since I'm not using QT/IMGUI which would've possibly made this a breeze. Hopefully SDL has something
Famicom emulation (& PAL support)

Mappers

According to this list (source info is currently down), the following mappers make up nearly 90% of the entire NES library, in order of popularity:

Low priority:

Mapper 206 (DxROM/earlier MMC3)
Mapper 11 (Color Dreams)
Mapper 5 (MMC5) (notably Castlevania III)
Mapper 19 (Namco 129/163)

Some notable mappers I want implemented as well:

Mapper 9 (just (Mike Tyson's) Punch-Out!!)

Building

Windows and Mac build information (and builds) can be provided soon. I am currently prioritizing development as the project is so early, namely getting more titles supported and controls support.
