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to change the duration of oxygen underwater, also updated the screenshots, the update was still showing images that no longer represent the current state of the hack.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.
This is a hack of Sonic the Hedgehog 2 for Sega Genesis. It changes the frequency of music and sound effects making for a different sounding game. Some music is barely recognizable and the game can feel quite different because of it.
The patch is in xdelta format. The ROM should be in BIN format.
