GameBoy Color

The GameBoy Color is the color version of the popular GameBoy. It also has a double-speed mode and infrared port.
To start developing for the GBC, you'll need a flash cartridge/programmer...

Misc

How to start?

* Download the SDCC GameBoy compiler: gbdk-win32
NOTE: most source codes on this site rely on the non-SDCC version.
* Search for the "Everything You Always Wanted To Know About GAMEBOY" document (aka GBSPEC). There are text and PDF versions. Msg me if you can't find it.
* Try to compile some programs... note that the latest GBDK might be a little incompatable with my demos/games.
* Try to make your own l33t demos/games :P
* More instructions later... :) for now... just follow the links and read some docs

Hashcam

Modified Hash emulator to support webcam. There's no dithering, contrast or brightness control. It just converts images to GB format and maps them in memory.

Gameboy Camera

GameBoy camera test stuff... grab a GB2PP cable... disassemble GBCamera cartridge... and try to make it work for yourself...
Please notify me when you have deciphered the workings of the gbcam controller.

Movieplayer / Movieracer

Hmm.. a grayscale movie player actually runs pretty smoothly.
Also a color movie player just needs to have the palette set each frame.

sorry, no downloads

GUI examples

Samples of GUI's like Mac,Windoze... resized to GBC size

3D wireframe cube

It's a bit slow using those old GBDK library calls...

Demo's & cool stuff

Dark Intentions

My cool demo that got 2nd in the GBdev2000 compo held by Quang. (damn... I never received the prize...)
Just look at that optimized 40x38 (4x4 pixel) rotozoomer (palette map is 8x8 pixel resolution).
I know the ending is pretty slow for fast readers but don't miss the fake startup sequence and a similar pling sound :)
