Edit Chainsaw codes

I think I done right, but game still crash. I change the 2 code for Drill, and then the rest of the Chainsaw ended with EAEAEA.

I used that code for a while so it should work. Does your rom has a header? If that's the case the code is 200 bytes later with headered roms.

If you used the previous patch already, make sure all data is reverted or at least the data at C2/3E6B since that part is not modified anymore.
