Super Mario Flash 2
Super Mario Flash 2 is the most true emulation of Super Mario World available today. The game includes a standard overworld map that reveals more of itself as you clear each stage as well as all the familiar characters of Super Mario World like Goombas, Koopas, Mole Men, Charging Chuck (the football dude), and most importantly... Yoshi! Yoshi is true to his Super Mario World form being able to crush foes by jumping on them or collect coins by eating them and he can even breathe fire if he swallows a red shell. This is easily the best Super Mario flash game ever.
