# 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.
|
|
|
|
|
|
Feel free to ask us on **[nucleus.kafuka.org #skeetendo](https://kiwiirc.com/client/irc.nolimitzone.com/?#skeetendo)** if something goes wrong!

|
|
# 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**.
|
|
|
|
* From the package selection, select **wget**.
|
|
|
|
|
|
## Using Cygwin
|
|
|
|
Launch the **Cygwin terminal**. Maybe you know your way around the Linux terminal, **bash**. If not, a crash course:
|
|
```bash
|
|
# 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 to be able to compile.
|
|
|
|
|
|
If you're feeling lazy, just paste these commands into your terminal.
|
|
|
|
|
|
**apt-cyg** lets you install new packages without running Cygwin setup.
|
|
|
|
```bash
|
|
wget http://apt-cyg.googlecode.com/svn/trunk/apt-cyg
|
|
chmod +x apt-cyg
|
|
mv apt-cyg /usr/local/bin/
|
|
```
|
|
|
|
Now we can use apt-cyg to install everything else.
|
|
|
|
```bash
|
|
apt-cyg install make git python python-setuptools unzip
|
|
easy_install pip
|
|
```
|
|
|
|
**rgbds** will let you compile Game Boy roms.
|
|
|
|
```bash
|
|
wget http://diyhpl.us/~bryan/irc/pokered/rgbds/rgbds-0.0.1.zip
|
|
unzip rgbds-0.0.1.zip
|
|
mv rgbds-0.0.1/* /usr/local/bin
|
|
rm -r rgbds-0.0.1*
|
|
```
|
|
|
|
Set up the **pokecrystal** repository:
|
|
|
|
```bash
|
|
cd ~
|
|
git clone https://github.com/kanzure/pokecrystal
|
|
cd pokecrystal
|
|
|
|
# install python requirements
|
|
pip install -r requirements.txt
|
|
```
|
|
|
|
## Don't forget baserom.gbc!!
|
|
|
|
Make sure you downloaded a base rom. Name it **baserom.gbc**.
|
|
|
|
Now you should be able to build **pokecrystal.gbc** for the first time.
|
|
|
|
This compiles a new rom from the source code, with any patches filled in from the base rom.
|
|
```bash
|
|
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!
|
|
|
|
Your first compile processes every source file at once. After that, **only modified source files have to be reprocessed**, so compiling again should be a few seconds faster.
|
|
|
|
Other **make targets** that may come in handy:
|
|
|
|
`make clean` deletes any preprocessed source files (.tx), rgbds object files and pokecrystal.gbc, in case something goes wrong.
|
|
|
|
`make pngs` decompresses any **lz** files in gfx/ and then exports any graphics files to **png**.
|
|
|
|
`make lzs` does the reverse. This is already part of the build process, so **modified pngs will automatically be converted to 2bpp and lz-compressed** without any additional work.
|
|
|
|
|
|
# Linux
|
|
|
|
```bash
|
|
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:
|
|
```bash
|
|
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?
|
|
|
|
**main.asm** is a good starting point. The structure of the source is laid out here.
|
|
|
|
* **Can't find something?** Anyone can add to the source. There's lots to be uncovered.
|
|
|
|
* **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](https://kiwiirc.com/client/irc.nolimitzone.com/?#skeetendo)**.
