I don't know that any Neo Geo game could be ported exactly to the Genesis/SNES, pixel for pixel (and including sound).I understand it as not showcasing the capabilities of the Neo Geo hardware - I would imagine that the game could easily be ported to Mega Drive / SNES / PCE without any drop in the quality of visuals / gameplay. The fact that for the price of the GP cart when new one could probably pick up a e.g. a PCE system + a quality shoot 'em up of choice doesn't help matters much either.
It's the best shooter on the Neo.
It wipes it's ass with Strikers.
