yah, now when you want to create patches..this becames problematic..

first of all: better is not to use automated tools, but try clear manual unpacking;
ok, this can be too much hard for you.

than 2nd suggestion:
unpack on both W9x & Nt systems, then compare RESOLVED imports;
when you see difference, now you need in debugger confirm exact import name;

(usually RestoreLastError sux:)
