Name: Blaster Master: Metafight Alpha
Function: Improvement
Author: Mister Xiado
Version: 1.0
Date: 20180905
Tools used: 
FCEUX for effecting hexadecimal changes
YYCHR and JASC Paint Shop Pro 7.04 for tile and sprite redraws
ReMaster for mapping changes
LunarIPS for extracting the IPS from the hacked ROM.

This hack for Blaster Master (NES) makes many of the graphics more similar to Blaster Master Zero (3DS, Switch), barring things that would be impossible on the NES. While many details are identical to those in Zero, palette, resolution, tile, and sprite limitations limit the similarity. Other graphical and map changes have been made to take advantage of wasted space, in the spirit of Blaster Master Zero. Some dungeons have been expanded and de-simplified, as well as some quality of life fixes in other maps.
This hack will not work with pre-existing TAS or human-play recordings due to layout changes in the maps that would place obstructions in the original maps' layouts.

How to use this hack:
Copy the original Blaster Master (US) ROM to a new location, or to a new filename in the same location, and using LunarIPS to bind the hack IPS file to the ROM.
