Just so everyone knows this game runs wonderfully with the Mesen emulator. In Mesen you can use a thumb or joystick to emulate what it would feel like if played in an actual arcade.
I would only suggest adding additional graphics modes such as mono and modes for people with visual impairments and color blindness. Things like adding darker boarders/better contrast in the background scenes especially in the buildings as they would appear washed out to someone with low vision.
