In this one, the wounds are white, and the screen flashes green (in two player, the screen flashes on the side corresponding to the player who got hit.) Sort of looks like glass being shot out.
-When you shot an enemy, they would fall backwards (or do something similar) and then flicker for a moment before disappearing. In this one, they wouldn't fall backwards, but they would still flicker and then vanish, only they would do so in the position that you shot them in.
-Shooting an innocent bystander or one of your own police comrades would result in a penalty of one life, and after every stage, if you earned any kind of promotion, you would get a demotion for however many innocent victims you shot. In this one, it's more like you're shooting AT them (or even wounding them if you will.) You will receive a penalty, but they don't die. It's more like being given a warning for shooting at an innocent.
-One of the missions dealt with a group of criminals who were attempting to smuggle illegal contraband into the country (OK, drugs, if you will!) Since drugs were a no-no by Nintendo, Konami apparently worked out a deal so that the smugglers were now illegal arms dealers.
