I found this thread by doing a forum search, but I must have misunderstood what the "painful chainsaw" patch does. I applied it manually (triple checked that I did it right) using the non-headered code posted by Warrax above (on a non-headered rom of course). Now it seems that the chainsaw NEVER does the instant death move - even against monsters that don't have immunity to instant death. Basically, the chainsaw is now just a more powerful Drill. I was under the impression the chainsaw was still supposed to perform the instant death move 25% of the time, but cause damage if it cannot kill? I attacked with the chainsaw nearly a hundred times to make sure I wasn't missing the special move, but it never happened.

Edit: Here is all the code I edited. There is nothing I am supposed to add in addition to the code posted by Warrax, is there?

Yes, but I just now tried on a vanilla 1.0 ROM with the same results (I made the same exact changes listed above). Has anyone actually verified that the instant death move works for them?

Edit: Even the original Painful Chainsaw ips (with the bugged drill) applied to a vanilla 1.0 rom does not seem to work. I attacked dozens of times with the chainsaw with no instant death move.

to ignore the animation: any times where an enemy with Current HP above the displayed damage perishes anyway?

Nope, I tested by giving several monsters 65,000 HP and attacked them about 30 times with the chainsaw.  They never perished until their HP ran out. It was a normal attack each time. This was with a vanilla 1.0 rom.

looks like the code posted in this thread is missing the edit to the C2/3DCD Special Effect Pointer table:

Code:
C2/3E6B: 8C 38
==>
Code:
C2/3E6B: 3B 2B

That seems to fix it! You actually pointed to the Scimitar slice effect instead of the normal chainsaw death - but I actually like it far better.  It makes more sense to have a monster sliced up after being attacked by a chainsaw...

no prob.  both the pointer change and the call to the Scimitar/X-Kill weapon function are actually part of the patch.  it's just that the former was omitted in Warrax's post, so the latter never got called for you.

I actually think it was missing from the original painful chainsaw patch in general, since I had the same issue with the ips patch on the web site. Either way, thanks for your help!
