SNES Opcode Searcher

SNES Opcode Searcher will find assembly instructions using only memory addresses. Just give it a ROM file and memory address (ROM or RAM) such as 7E1D00, and it will search for instructions like LDA $7E1D00, CMP $1D00,X, and even EOR $1D00! New version 0.1.4b adds everybody’s favorite INC, DEC, STZ, and more.
You can provide a single address, or a range of addresses (start and end). It supports 16 bit (short) and 24 bit (long) addresses. But that’s not all. It tells you where in the file it was found, even accounting for those pesky SNES ROM headers. This tool will help even an assembly beginner track down assembly code locations, which can then be edited using a hex editor, xkas, or Asar.
Bonus: for those of you interested in ancient and antiquated scrawl, phonymike has also included the C source code.
