PHP Terminal GameBoy Emulator

Want to play Dr Mario or Pokémon on your server terminal? That's for you!

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 😄 and, come on, that's funny! 👯

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 😞

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:

  • Code standard - PSRs, please!
  • Array of functions - Maybe in PHP it's not the best approach
  • 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!
