First, find the old Nurse Joy script. Now, convert it all to dynamic offsets: ex change #org 0x800000 to #org @offset1.
Remember to find where all of the pointers and such go to and change those also.
When you are done with that, go into the documentation provided for JPAN's hack and look at the section on how the sethealingplace command has changed. Rewrite the sections of the script that contain it to match.
With this method, you only need to deal with the set healing place and nothing else.
Also, is this your hack? LoA? Did you just erase all of it?
