Last weeks' Japanese charts aren't in just yet, but based on VGChartz preliminary numbers, Shooting Star Rockman 3 is pretty much dead sales wise.
Pictured is the preliminary Nintendo DS sales chart. Notice the cut off at Higurashi no Nakukoru ni Kizuna: Dai-Ni-Kan? Anything below that game most likely brought in less than 11,000 or so units. Based on SSR3's position last week....well, let's just say the game might be in the thousands by now. Not too good at all.
Still, these are just preliminary numbers, nothing official yet. The "real" sales numbers should be up and out sometime tomorrow.
