As a result, editing the palette itself changes the monster from purple to red as well as the blood on the Game Over screen. The problem with this is that the palette is not exclusive to the blood sprites and is used by other things, including the big purple monster that the player character can transform into after drinking a potion. There is an earlier version of this blood mod by DackR, who changed the blood drips from purple to red by directly editing the colour palette used by the sprites. To use both together, you can simply apply either one of the two patches to your source ROM, then take your newly patched ROM and apply the second patch to that to get a final ROM with both mods activated! If you like this mod, you can combine it with Stanley_Decker & sloat’s Reverse Inventory Cycling to further enhance your game.

This patch exists to do one thing and one thing only: uncensor the purple blood of the Game Over screen in the US SNES version of Zombies Ate My Neighbors to closer match the red blood seen in the Mega Drive / Genesis release.
