1943 was one of my favourite games in the arcades and the NES port is arguably excellent. The music is ported well and the gameplay is very good and responsive. However, my only problem with this port is that when you are below 20 helath, the excellent music gets spoiled with a god-awful and extremely annoying warning music that completely ruins the game's atmosphere and also make my ears want to puke. This patch does exactly what it says and i can say that this gives at the game a much better experience. Totally Recommended!!!
