MDbtroid        PC/Mac        Infinity's End        17.3k .zip


Metroid Presented by the Metroid Database, or "MDbtroid" for short, is basically a graphical hack of the original NES game. The game has been improved upon in many different ways, including Samus's animation cycle, redrawn and enlarged bosses, a beautiful new opening title screen, new ending graphics, new Suitless Samus sprites, and all the enemies have been carefully redrawn. See the included .txt file for more details on what else has been changed.

For the full MDbtroid experience, we also recommend you play the game utilizing the Lua Script created by Neill Corlett (FCEUX is required). This script allows you to play the game with a minimap and timer in the upper left corner, adds a map and an inventory screen when you pause, and gives you the ability to turn off your items at will! It also gives you full health and missiles after death. Playing Metroid has never been this much fun!

You'll need the MDbtroid patch, an IPS patch utility , a NES emulator, and the Metroid ROM. A Readme containing instructions for use is included in the zip file.

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

用上述脚本，可以给metroid加上切换武器的功能。

此外加上了地图。
