Aero Fighters 3 / Sonic Wings 3 ROM

(Very similar to Aero Fighters 2, with some slightly better graphics and a couple new characters.)
A humorous vertically scrolling shoot-em-up in which you can play as characters ranging from a cyborg to a talking dolphin. Each character has unique dialogue between levels, including when playing in two-player mode. After some stages is a bonus stage of sorts where you can attack loads of one hit kill helicopters to fully power-up your plane easily. Each character has a unique ending, however you have a limited amount lives no matter how many coins you have when you play the last stage, so be careful.

A good game to play with a friend or by yourself.
