All of the information about this project is on the class Wiki : http://wwwx.cs.unc.edu/~joat/fpga3d/index.php

My good friend Jeff Frohwein has started production of his MultiBoot Version 2 cable, which allows you to download up to 256 kbytes of code to your Gameboy Advance and test your programs on the actual hardware. I have one and I must say it is a wonderful development tool.
Update: The first batch of 50 cables sold out rapidly, but there are more batches on the horizon, check www.devrs.com/gba periodically for more information.
