Getting Started

Compiling pokecrystal.gbc requires a certain Pokemon Crystal rom:

Pokemon - Crystal Version (UE) (V1.0) [C][!].gbc
md5: 9f2922b235a5eeb78d65594e82ef5dde

Save it as baserom.gbc in the repository.

Windows

If you are on Windows and can't install Linux, Cygwin is a great alternative.

Installing Cygwin

Cygwin provides a virtual Linux environment on Windows systems. Just get setup.exe.

http://cygwin.com/install.html

During the install:

Keep the defaults.
Most mirrors are molasses. Use http://mirrors.kernel.org.

Using Cygwin

Launch the Cygwin terminal. Maybe you know your way around the Linux terminal, bash. If not, a crash course:

# list files in current directory
ls

# show current directory
pwd

# change directory
cd /away/we/go

Getting up and running

We need a couple more things.

apt-cyg install python make git wget

rgbds will let you compile Game Boy roms.

# download rgbds binaries
wget http://diyhpl.us/~bryan/irc/pokered/rgbds/rgbds.zip
unzip rgbds.zip
rm rgbds.zip

# make rgbds accessible for all time
export PATH=$PATH:`pwd`/rgbds
echo "export PATH=$PATH" >> ~/.bashrc

Set up the pokecrystal repository:

cd ~
git clone https://github.com/kanzure/pokecrystal
cd pokecrystal

# install python requirements
pip install -r requirements.txt

# use hexdump to diff binary files
git config diff.hex.textconv hexdump

# download the base rom

Now you should be able to build pokecrystal.gbc for the first time.

make

This ought to take between 3 and 15 seconds, depending on your computer.

If you see cmp baserom.gbc pokecrystal.gbc as the last line, the build was successful! Rejoice!

Linux

sudo apt-get install make gcc bison git python python-setuptools 

# unittest2 is required if using python2.6
sudo easy_install unittest2
sudo easy_install pip

# download rgbds source code
git clone git://github.com/bentley/rgbds.git

# compile rgbds
cd rgbds
make
sudo make install

# check if rgbasm is installed now
which rgbasm

# download pokecrystal
git clone git://github.com/kanzure/pokecrystal.git
cd pokecrystal

# install python requirements
pip install -r requirements.txt

# use hexdump to diff binary files
git config diff.hex.textconv hexdump

To compile the rom from asm source:

make

That will take between 3 and 15 seconds, depending on your computer. If you see cmp baserom.gbc pokecrystal.gbc as the last line, the build was successful! Rejoice!

Now what?

Can't find something? Contribute!
Do your own thing! The asm source is hack-friendly, and the supplementary scripts in extras/ can be used for other projects.
We'll be happy to answer any questions on nucleus.kafuka.org #skeetendo.
