Menu "Edit/Patch program/Search & Patch"
I've made it when was analyzing corrupted binary (memory dump) to fix broken imports. Format of the Search-and-Replace hex string is the same as in IDA "Binary Search" (menu "Search/Sequence of bytes... Alt-B"). Bytes marked by question mark '?
' in replace sting be substituted by found values. You are will be asked for each replace confirmation.
