Challenge 6 Years [TeamEurope, SSJ, Youkal3]

- moved pockchal.cpp and the new driver to a benesse folder, as benesse had many more products

- created a separate machine for the Pocket Challenge v2, the BIOS isn't dumped, but carts aren't physically compatible with a Wonderswan even if the software is.  Makes more sense to have a driver with the borrowed Wonderswan BIOS marked as BAD_DUMP than hiding everything behind the Wonderswan itself.
