It can run a Gameboy virtual machine by emulating its hardware and executing games Z80 CPU assembly code with PHP code.

The Gameboy screen is outputted to the terminal console using braille characters. Keyboard inputs are mapped to Gameboy key controls.

Why

Some people will ask me: _"Why you did that?"_

Well, a friend asked me _"What PHP can do?"_. I thought about that awhile and the idea came up. With PHP7's performance improvement now it's possible to emulate some systems :smile: and, come on, that's funny! :dancers:

It's based on the GameBoy JS Emulator.

Requirements

The following PHP versions are supported:

  • PHP 5.6
  • PHP 7
  • HHVM

You will need a good terminal! I've tested only on MacOSX and Linux. I'm sorry about that Windows guys :disappointed:

Installation

Using composer:

$ composer g require gabrielrcouto/php-terminal-gameboy-emulator:dev-master

Using PHAR:

$ wget https://raw.githubusercontent.com/gabrielrcouto/php-terminal-gameboy-emulator/master/bin/php-gameboy.phar
$ chmod +x php-gameboy.phar
$ mv php-gameboy.phar /usr/local/bin/php-gameboy

Running

Your roms are loaded from the directory you are running the php-gameboy command.

$ php-gameboy drmario.gb
$ php-gameboy pokemon.gbc

If you like to run this emulator locally, simple clone the repository:

$ git clone https://github.com/gabrielrcouto/php-terminal-gameboy-emulator.git
$ cd php-terminal-gameboy-emulator
$ composer install -o

For running roms, pass the full path to your rom or put then in the php-terminal-gameboy-emulator folder:

$ bin/php-gameboy pokemon.gbc
$ bin/php-gameboy /full/path/to/your/rom/drmario.gb

  • Left = A
  • Up = W
  • Down = S
  • Right = D
  • A = Comma (,)
  • B = Dot (.)
  • Select = N
  • Start = M

Tests

You can use the following command to run the most common checks, such as php -l, phpcs:

$ ant check

TO-DO

Converting from the JS paradigm was a lot of work, and I still need to adapt somethings like:

  • [x] Code standard - PSRs, please!
  • [x] Array of functions - Maybe in PHP it's not the best approach
  • [x] Pixel auxiliary array - Very CPU intensive to convert RGBA every time
  • [ ] Classes - Core is too big!
  • [ ] Profiling and otimizing - XHProf to find the most intensive functions
  • [ ] Save/Restore - I need to save my Pokémon, please!
