Changed description to reflect this being a bugged version with the update released as a separate patch. 5667 contains the functioning reworked patch, which was made in the more functional DSPRE while this one, 5657, was made in PPRE which is prone to making bugs. This page can be deleted as needed.
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.
