Added patch, to change the duration of oxygen underwater, also updated the screenshots, the update was still showing images that no longer represent the current state of the hack.
On the other hand, the changes in the ROM information had not been reflected either.
The Japanese version of Mega Man 4 has an unused tile in the title screen graphics that perfectly fits into the black space at the bottom corner of the helmet’s ear. This patch uses this tile for its intended purpose.
This patch also fixes some probable mistakes and regressions from previous games:
Correct Roll’s face palette when the screen turns sepia (part of her skin was eye-colored)
For the ending, add a pixel of hair by Mega Man’s neck (match Mega Man 2)
For Mega Man’s run sprites, add back part of his shoulder and layer his face so it is under his arm (match Mega Man 1 and 2)
Fix Rush’s menu animation so his back leg bends instead of using a duplicate tile of his standing leg (match Mega Man 3)
