Metroid X

This is one of the earliest hacks for the original Metroid. Screens, enemy and item placement, palettes, text, and more are all changed. The primary goal was to make the game more playable - the discerning player will note the careful placement of platforms and enemies to make jumps easier. However, beating the game will not be a cinch. Items are much more difficult to get, corridors are contorted into winding mazes, and many of the energy tanks have been completely eliminated.
