It'd be cool if there were a red-or-green blood toggle that enables a recoloring of the blood sprites to match their appearance in the Japanese version, similar to the violence level options in Turok 1 and 2.

Likewise, a ROM built from the Japanese version could provide a red palette for red blood mode.
