so yeah there are instructions for the patch but I wasn't able to completely follow them. The relevant instructions are:
-Move your ROM, the 'Lock.dmp' file, and the appropriate script file for the game you're using into
the same folder as the Assembly Patcher.
-Rename your ROM to 'fe7.gba' if using FE7, or 'fe8.gba' if using FE8. If you can't see the .gba
extension on your ROM already, don't add it in.
-Drag the script file onto 'run.py'.
-Now a command line will ask you twice where you want to place the hack. Input the offset of the
free space you're using (without adding 0x8000000) both times.
-The offset you choose MUST be word-aligned (ie divisible by 4).
-When it's done, enter in 'quit' or close the command line.
I wasn't sure what the script file was because that was the only mention of it, but I assumed it was the other text file in the folder (which if you look at it, it definitely looks like it could be a script). So I followed the first step completely, but I couldn't drag the text file onto run.py to start the program.
So then I ran run.py by itself and typed:
and I got this message:
