About

This hack came about as part of the SMB Special on NES [1] project. During the
course of the project, it was noticed that level 4-4 seemed to have been
corrupted. This patch aims to correct this.

The restored level is belived to be exactly as Hudsonsoft intended it to be.
However, this patch has not been properly tested. A variation of the patch
which inserted the corrected level 4-4 in place of level 1-1 has been tested.
This version, which placed the corrected level in it's proper place has not
been tested by me, because I suck at SMBS so bad I can't reach 4-4.

Please report any testing results (good or bad) to me. I can be reached at
"levi at gis dot net". Additionaly, I could use some proper before and after
screenshots of the effect area. Preferably one set coming in from the tunnel
below and another comming in through the pipe above. Thanks in advance.

Installation

To install the patch onto a SMB Special disk image, use your favorite IPS
patching utility. As alway, it's recommended that you back up your image first
in case something goes horribly wrong.

Uninstallation

If, for whatever reason, you decide that to remove the patch, a reverse patch
has been provided for your convenience.

Technical Details

The short story is that the data was recovered by a combination of clever
guesswork, examining the expected compressed vs. uncompressed size of the
missing data, and the sheer luck of finding part of the missing data elsewhere
in the disk image.

For the full story, see the posts [2] I made on the subject on the SMB Special
for NES thread at RHDN.
