To build the GP2X version, run the script buildall.gp2x.sh

Note: ports/gp2x/Makefile contains the location of the SDK, I use oopo's toolchain.  If you don't change the compiler name and SDK path in the Makefile

To install:
1) Copy the Powder2X directory from port/gp2x to your SD card. 
2) Copy the executable powder from port/gp2x to Powder2X/pdata on the SD card.
3) Copy the gfx and rooms directories to Powder2X/pdata on the SD card.
