				EMULATOR
```

A nearly complete NES emulator in a single 700-line C++ source file, based on [LaiNES](https://github.com/AndreaOrru/LaiNES).

```
cloc main.cpp
       1 text file.
       1 unique file.                              
       0 files ignored.

## Features
- Cycle accurate
- Extremely compact: only 700 lines in one source file with no dependencies

## Requirements
- C++11
- SDL2

## Building
### *nix systems
```sh
git clone --recursive https://github.com/Ta180m/BadNES && cd BadNES
g++ main.cpp -o badnes -std=c++11 -lSDL2main -lSDL2
```

### Windows
```sh
git clone --recursive https://github.com/Ta180m/BadNES && cd BadNES
g++ main.cpp -o badnes -std=c++11 -IC:\mingw\include\SDL2 -LC:\mingw\lib -w -Wl,-subsystem,windows -lmingw32 -lSDL2main -lSDL2
```

## Usage
```sh
./badnes [path to rom]
```

## Compatibility
BadNES implements the most common mappers, which should be enough for a good percentage of the games:
- NROM (Mapper 000)
- MMC1 / SxROM (Mapper 001)
- UxROM (Mapper 002)
- CNROM (Mapper 003)
- MMC3, MMC6 / TxROM (Mapper 004)

You can check the compatibility for each ROM in the following list:

## FAQ
### Why the name?
http://www.usaco.org/index.php?page=viewproblem2&cpid=1041

### Why did you do this?
I really like LaiNES: it's very minimal and compact -- but it has several dependencies, so I try to write the shortest NES emulator possible, in a single source file.

### There's no sound!
I'm working on it right now.

### What do you mean by "nearly complete"?
I will declare it complete once I finish implementing the APU, savestates, and maybe Mapper 7.

Special thanks to [Andrea Orru](https://github.com/AndreaOrru) for creating [LaiNES](https://github.com/AndreaOrru/LaiNES), the emulator that this project derives much of its code from.
