Finally got to play this on original hardware! It's pretty fun but doesn't last too long. I can see myself replaying this for the trick shot mode, it was quite challenging and precise when sitting away from the TV.
In contrast, Game A was boring. You shoot one or two guys and have to wait for new ones to come on screen. Game B was alright, I liked the side scrolling environment compared to Game A because the gang members were in various places instead of a straight line.
Pretty short experience, good amount of potential replay value. If you can play this with a zapper instead of emulation, it's pretty fun!
