New WORKING Game

--
Hammer Away (prototype) [( Atro - from Neo-geo.com aka Rui Baptista ) ( _rm_ - from Neo-geo.com aka Ricardo Marques)  ( 1up - from Neo-geo.com aka Daniel "casebres" )]

(not extensively tested, but seems to work, needed irq0 on the sound cpu from the YM, also has more tiles than any other game, might tweak the code further)
(ROM check fails, but I assume that's just because it's a proto.)
