[WIP] Super Mario USA 2

A remake of Super Mario Bros. 2 on the Gameboy. Rather than starting from the NES version, I used the Gameboy Advance (Super Mario Advance) as a reference. This is a mere WIP and many features aren't implemented (carry objects, stand on enemies, crouching...).

You can play with different characters (no gameplay difference at the moment):

• Toad
• Toadette
• Yoshi
