This is a Lua script for FCEUX that adds some new stuff to an old game, Metroid:
• Equipment menu that lets you toggle powerups, including the Ice and Wave beams
• Maximum energy tanks raised from 6 to 7
• Start out with full health and missiles
• Minimap and large map on pause screen, with mouse interaction (tooltips / click elevators to navigate between areas)
• Clear time and item percentage
• Max missiles display
• Countdowns on broken blocks
• Popup boxes when you collect a powerup
• Mouse input on password screen
