New Games supported or promoted from GAME_NOT_WORKING status:
-------------------------------------------------------------

Several ST-V games are probably now playable, however be warned many are very very
slow, this is not a bug, sound is still poor or non-existant in most titles, these
haven't been tested for long so could easily fail at later levels.  Games which
were marked as working in previous updates are also improved (shienryu etc.)
	[David Haywood, Angelo Salese, Olivier Galibert]

	Puyo Puyo Sun - some priority glitches, otherwise looks good
	Mausuke Ojama the World - mostly ok
	Ejihon Tantei Jimusyo - missing alpha effect on lens
	Virtua Fighter Kids - bad sprite colours, missing ground effects
	Columns 97 - miscoloured sprites, background not correctly scaled
	Cotton 2 - missing ground in places
	Cotton Boomerang - missing ground in places
	Die Hard Arcade / Dynamite Deka - missing floors / ceilings

	there might be others too, a few can certainly be watched.  this driver still
	needs a lot of work, I don't expect it to be completed soon due to the
	incredible complexity of this hardware.
