You don't need to do all that, PPSSPP supports memory searching. Just click in the memory window and hit ctrl+s, put in the hex of what you're looking for (text isn't supported) and it'll find it. So just copy a bunch of the m3000.bin, and then find it in memory. It only gets loaded when the game needs it, so you won't find it when on the main menu, and it's gone after you finish that second cutscene and you go over to the train scene, where it gets replaced by the script for that train scene.
I listed 2 locations for you to go to in the disassembler though: 0880A004 and 089477BC. Put those in the box in the top-left and hit enter, and then double click on where it takes you to. Doing that memory searching for the file is how I found those places to begin with, and I know there's a few more, not sure why there needs to be multiple though.
