Reducing epileptic potential of Bum Rush

It seems that the only other mention of photosensitive effects between versions is that the PlayStation has four softer white flashes for Bum Rush.  I don't know what to do to make that happen, but it could be an option for someone with more experience with timing in hex code commands.  I know the other attacks might have something of a photosensitive nature, but it's pretty telling that only Bum Rush got special treatment for it...  It's still a good idea to look into.  I haven't tested the results of my edits in different backgrounds (Can be learned at level 70, so even WoB maps and battles ought to be tested if need be) to see if there are unexpected errors or behavior but I can make a .ips later today to post.
