If you are interested, I can send the physical gerber layer for a
board I developed to run on a GBC, but later modified for GBA. The
board is 0.1 inch thick and is not inserted in a plastic case.
Instead, there a plastic cover mounted on the board, thereby avoiding
the cost of a plastic enclosure. I have added a pair of "fingers" on
each side of the board to trip the GBA microswitch to place it in GBC
compatibility mode. These fingers will not be needed for a native
GBA board. You can see photos at www.databoy.netfirms.com.
Note: I developed my PCB using the free version of the Eagle layout
editor (www.cadsoft.de).
