Here’s one of my favorite portable gaming hacks, the GBA GPS. It’s a project that always comes to mind whenever I hear about some piece of homebrew development hardware falling under legal scrutiny.
People are always creating amazing things when closed hardware is hacked open for amateur development.
I own Magellan meridian GPS, many efforts were done to create custom maps for the receiver (see Links to my Magellan GPS page). But most of the mapping receivers (Magellan, Garmin) use vector graphics, this is very good for scaling, search, and huge amount of data. But sometimes much more convenient to have raster map with the current position on the map. I developed this GBA based mapping receiver to use scanned maps with GPS the way I like. This was done for fun, but I found this device very useful. I am using this device as a car navigator in the city.
