Hardware > GBA to USB cord diagram

is it possible that anyone could spare me a diagram of a cord that would connect my GBA to my USB or possibly my Parallel port?

Short Answer NO.

Long Answer:
It wouldn't be just a cord to interface into a USB port.

  1. USB is not an RS232 port and requires quite a bit of software to be written
  2. You need a physical interface conversion
  3. You need a USB egnine to support an isochronise protocol and handle endpoints etc.


Parallel port
Maybe
You have to use the multiboot protocol to do this, which requires some knowledge of

  1. How the GBA multiboot protocol works
  2. How the physical interface operates (IE data formating etc)
  3. How to write a boot program that will load data into the GBA to do whatever it is you want to do.

A UART communication cable is pretty easy to build. Try http://darkfader.net/gba/main.html and http://frotz.net/gbadev/ for some more info.

If you're just gonna put multiboot roms on the GBA then all you need is an Xboo cable which is very easy to build. The UART cable seems a bit tough to make, but if you're used to making that kind of stuff then go ahead. But, you'll need to have software.
