They both have a "twin", that only differs on the m3 and m6 part. The first ones listed are in uppercase, these ones are in lowercase. Suggestion is to make the second ones uppercase as well, and add [a] to them both. This way they are in same case but can coexist in windows. As is now, they will be separate files in linux but in windows they will owerwrite each other. Plus it makes no sense that one is lowercase m and the other one us uppercase. Unless of cource that is how they present in the game, which I doubt.
