yenatch 4bc2564a6b VBlank and dependencies
VBlank has seven different modes. The one that sees the
most use is mode 0, which performs all basic display and
audio functions. The purpose of the others is unknown.

VBlank relies on the following functions:

-joypad
-cgb palette update
-dmg -> cgb pal conversion
-bg map update
-vram tile update
-tile animations
-serial request
-game timer

Tile animation is large enough to warrant its own commit.

Pokémon Crystal

This is a hand-crafted disassembly of Pokémon Crystal.

The source code in this project successfully converts back into a ROM image. All source code is meticulously commented.

Base ROM

The following ROM is required for compiling:

Pokemon - Crystal Version (UE) (V1.0) [C][!].gbc

md5: 9f2922b235a5eeb78d65594e82ef5dde

Eventually this will not be necessary.

Installing

Simple.

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

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

# 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 https://github.com/kanzure/pokecrystal.git
cd pokecrystal

make clean && make

Also, there are Windows installation instructions.

Assembling

  • To assemble, first install RGBDS and put it in your path. The version of RGBDS needed is rgbds-linux.

  • Next, copy the Pokémon ROM to this directory as "baserom.gbc".

  • Then run "make" in your shell.

  • This will output a file named "pokecrystal.gbc".
