# Waterfoul

Waterfoul is a Gameboy emulator written in Ruby-lang. It is a casual excersize by myself to learn the internals

of the device and how it works.



## Getting Started

To start the emulator:



`bundle exec exe/waterfoul start `



Make sure to `bundle install` first and install required libraries.



By default the emulator will run the boot rom, if you wish to skip it then add `--skip-boot` as an option.



## Try turning on the --jit and --enable-frozen-string-literal to get max fps

`RUBYOPT="--enable-frozen-string-literal --jit --jit-max-cache=100000 --jit-min-calls=3" bundle exec exe/waterfoul start `



## Requirements

The [sdl2](https://www.libsdl.org/download-2.0.php) library is currenty used to render pixels. Most platforms have packages avaliable, else see [here](https://wiki.libsdl.org/Installation). This library is required and needs to be installed before you can run the emulator.



## Can it play roms?

Yes! but the list of roms that i know work is very limited to just Tetris, Super Mario Land and Pokemon Red. But a lot of work is being put into making other games compatable. The device does run the internal boot program succesfully and is passing test programs sucesfully (barggs).



## Controls

The following shows the mapped keys to control the game.

## Testing

If you wish to run the test suite, download the source code (make sure to run `bundle install`) and run `bundle exec rspec`
